Intended Use / Indications for Use
The reticONE™ SYSTEM for EPICS® XL™ Flow Cytometry Systems combines a reagent kit consisting of a Coriphosphine-O dye and a Biological Calibrator, and software for automated analysis of reticulocytes in whole blood using EPICS® XL™ Flow Cytometry Systems with SYSTEM II™ Software. The system is intended "For In Vitro Diagnostic Use" and allows identification and enumeration of reticulocyte percentage and absolute count.
The reticulocyte count is diagnostically useful in discriminating between normal erythropoiesis. It can be useful in the diagnosis or detection of anemal hemorthaging, hemoglobinopathies and certain nutritional or vitamin deficiencies. Decreased or defective red cell production may result in a lower reticulocyte count such as in aplastic anemias. Elevated reticulocyte counts may be observed in clinical conditions where red cell destruction is increased (for example, hemolytic anemias and hypersplenism) or where there is increased red cell production (for example, erythropoietin drug therapy and a response to treated anemia).
Since the kidneys are a primary source of erythropoietin (a hormone that regulates erythroid development), the reticulosyte count is also affected in individuals with renal disease. In cases of renal atrophy, the reticulocyte count will be decreased. In cases of malignancy or hypersplenism, the reticulocyte count will be elevated.
Reticulocyte counts are also used as an indicator of bone marrow recovery following intensive or a bone marrow transplantation. Increased reticulocyte counts in these patients are indicative of bone marrow regeneration.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
**Product testing to assess the performance of the reticONE™ SYSTEM is described below. Studies were Product Testing: designed in line with instructions for use given in the reticONE™ SYSTEM Guide, Package Inserts, Product Manuals, and performance specifications. Specimens were assayed with Retic-COUNT™ for comparison purposes. The results of product testing demonstrate that the retic-ONE™ SYSTEM meets all performance specifications and provides reticulocyte percentage and absolute count values comparable to those of Retic-COUNT™.
1. Stability Studies:
Three studies were carried out to demonstrate whole blood specimen and sample stability claims for the reticONE™ SYSTEM.
a. Stored (Unstained) Whole Blood Specimens Held for 72 Hours at 2-8 ℃: Normal whole blood specimens (n = 3) were collected by venipuncture into K,EDTA and ten replicate samples prepared for each specimen for each of four time points: 0-hours; 48-hours; and 72-hours; and 72-hours after collection. The 0-hours samples were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The remaining samples were stained and analyzed for reticulocyte percentage after either 24-hours; or 72-hours of storage at 2-8°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
b. Stored (Unstained) Whole Blood Specimens Held for 6 Hours at 20-25 ℃: Normal whole blood specimens (n = 10) were collected by venipuncture into K,EDTA and ten replicate samples prepared for each specimen for each of two time points: 0-hours after collection. The 0hours samples were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The remaining samples were stained and analyzed for reticulocyte percentage after 6-hours of storage at 20-25°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
C. Stored Prepared (Stained) Samples Held for 6 Hours at 20-25 ℃: Normal whole blood specimens (n = 5) were collected by venipuncture into K.EDTA and ten replicate samples prepared for each specimen. The samples (0-hours) were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. These same stained samples were reanalyzed for reticulocyte percentage after 6-hours of storage at 20-25°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
The results for the three stability studies clearly demonstrated that the reticONE™ SYSTEM meets stability claims for both stored (unstained) whole blood specimens and prepared (stained) samples under the storage times and temperature conditions studied.
2. Carryover Study:
Carryover percent was evaluated on two EPICS® XL-MCL™ flow cvtometers by the approved NCCLS procedure for high-to-low carryover testing in a reticulocyte flow cytometric analysis system [NCCLS Document H44-A]. The High Level and the Low Level of the Streck Laboratories, Inc® multiple-level Reticulocyte Control product, Retic-Chex, were used in place of a whole blood specimen with an elevated RBC count and a whole blood specimen with a low RBC count. A single sample was prepared for each Level and stained with the COULTER® reticONE™ Reagent Kit. The stained High Level samples were then analyzed for reticulocyte percentage in three successive runs (Runs: 1), I, 1, 1, using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The stained Low Level samples were next analyzed in the same manner (Runs: J, J, J.). All sample staining and analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. Carryover percent was calculated using the following equation: Carryover Percent (%) == [{J ] - J x 100] == [(1} - J}). The results for the carryover study clearly demonstrated that the reticONE™ SYSTEM exhibits minimal carryover compared to the Flow Cytometer Specification.
3. Linearity Study:
Two (n = 2) whole blood specimens were collected by venipuncture into K,EDTA and serially diluted (n = 10 data points: low, high and 8 serial dilutions in between) to achieve a defined range of 0.2% to 12.5% reticulocytes. A sample was prepared for each data point and stained with the COULTER® reticONE™ Reagent Kit. Three replicate measurements of reticulocyte percentage were then made for each stained sample using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. All sample staining and analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. The results were analyzed in terms of regression and correlation analyses for recovered versus expected reticulocyte percentage. The results for the linearity study clearly demonstrated linearity over the defined (reportable) range for the reticONE™ SYSTEM.
4. Precision Study:
Three studies were carried out to demonstrate the reproducibility of the reticONE™ SYSTEM.
a. Within Run (Intralaboratory) Precision: Measurements were made on sample [normal or abnormal] whole blood specimens for each of five levels of reticulocyte percentage using one EPICS® XL-MCL™ flow cytometer. All measurements were made in replicates of ten determinations. Results were analyzed in terms of mean reticulocyte percentage, standard deviation (± 1 SD) and coefficient of variation (%CV).
b. Interlaboratory Precision: Measurements were made on samples from a single [normal] whole blood specimen for one level of reticulocyte percentage on the same day by three laboratories using different EPICS® XL-MCL™ flow cvtometers. All measurements were made in replicates of ten determinations. Results were analyzed in terms of mean reticulocyte percentage, standard deviation (± 1 SD) and coefficient of variation (%CV).
C. Site Precision: Measurements were made on sample [normal or abnormal] whole blood specimens for each of five levels of reticulocyte percentage using one EPICS® XL-MCL™ flow cytometer. All measurements were made in replicates of ten determinations. Results were analyzed in terms of mean reticulocyte percentage, standard deviation (± 1 SD) and coefficient of variation (%CV).
The results for the three precision studies clearly demonstrated the reproducibility of the reticONE™ SYSTEM.
5. Accuracv Study:
Normal and abnormal whole blood specimens were collected from geographically diverse populations of males and females unselected as to race and ranging in age from 18 to 85 years. Specimens were divided, processed and assayed in parallel with reticONE™ SYSTEM and Retic-COUNT™. Reticulocyte percentage (%) and absolute count (cells/uL) values were determined with EPICS® XL-MCL or FACScan™ flow cytometers (as applicable). Red blood cell counts were obtained using a COULTER® STKS™ Analyzer. The results were analyzed in terms of minimum, maximum, mean, standard deviation (± 1 SD), confidence intervals with 95% limits, regression and correlation analyses, and analyses of variance. The results for the accuracy study clearly demonstrated that the reticONE™ SYSTEM and Retic-COUNT™ identify and enumerate comparable numbers of reticulocytes in whole blood specimens.

Product testing to assess the performance of the reticONE™ SYSTEM is described below. Studies were Product Testing: designed in line with instructions for use given in the reticONE™ SYSTEM Guide, Package Inserts, Product Manuals, and performance specifications. Specimens were assayed with Retic-COUNT™ for comparison purposes. The results of product testing demonstrate that the retic-ONE™ SYSTEM meets all performance specifications and provides reticulocyte percentage and absolute count values comparable to those of Retic-COUNT™.
1. Stability Studies:
Three studies were carried out to demonstrate whole blood specimen and sample stability claims for the reticONE™ SYSTEM.
Stored (Unstained) Whole Blood Specimens Held for 72 Hours at 2-8 ℃: a.
Normal whole blood specimens (n = 3) were collected by venipuncture into K,EDTA and ten replicate samples prepared for each specimen for each of four time points: 0-hours; 48-hours; and 72-hours; and 72-hours after collection. The 0-hours samples were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The remaining samples were stained and analyzed for reticulocyte percentage after either 24-hours; or 72-hours of storage at 2-8°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
Stored (Unstained) Whole Blood Specimens Held for 6 Hours at 20-25 ℃: b.
Normal whole blood specimens (n = 10) were collected by venipuncture into K,EDTA and ten replicate samples prepared for each specimen for each of two time points: 0-hours after collection. The 0hours samples were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The remaining samples were stained and analyzed for reticulocyte percentage after 6-hours of storage at 20-25°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
Stored Prepared (Stained) Samples Held for 6 Hours at 20-25 ℃: C.
Normal whole blood specimens (n = 5) were collected by venipuncture into K.EDTA and ten replicate samples prepared for each specimen. The samples (0-hours) were stained and analyzed for reticulocyte percentage within 30 minutes of specimen collection using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. These same stained samples were reanalyzed for reticulocyte percentage after 6-hours of storage at 20-25°C. All analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. The results were analyzed in terms of reticulocyte percentage and standard deviation (± 1 SD) for each donor.
The results for the three stability studies clearly demonstrated that the reticONE™ SYSTEM meets stability claims for both stored (unstained) whole blood specimens and prepared (stained) samples under the storage times and temperature conditions studied.
2. Carryover Study:
Carryover percent was evaluated on two EPICS® XL-MCL™ flow cvtometers by the approved NCCLS procedure for high-to-low carryover testing in a reticulocyte flow cytometric analysis system [NCCLS Document H44-A]. The High Level and the Low Level of the Streck Laboratories, Inc® multiple-level Reticulocyte Control product, Retic-Chex, were used in place of a whole blood specimen with an elevated RBC count and a whole blood specimen with a low RBC count. A single sample was prepared for each Level and stained with the COULTER® reticONE™ Reagent Kit. The stained High Level samples were then analyzed for reticulocyte percentage in three successive runs (Runs: 1), I, 1, 1, using the reticONE™ SYSTEM and EPICS® XL-MCL™ flow cytometer. The stained Low Level samples were next analyzed in the same manner (Runs: J, J, J.). All sample staining and analyses were carried out at 20-25° using the procedures described in the reticONE™ SYSTEM Guide. Carryover percent was calculated using the following equation: Carryover Percent (%) == [{J ] - J x 100] == [(1} - J}). The results for the carryover study clearly demonstrated that the reticONE™ SYSTEM exhibits minimal carryover compared to the Flow Cytometer Specification.

INDICATIONS FOR USE
199032
510(k) Number (if known): Not Yet Assigne
reticONE™ SYSTEM for EPICS® XL™ Flow Cytometry Systems Device Name:
Indications For Use:
The reticONE™ SYSTEM for EPICS® XL™ Flow Cytometry Systems combines a reagent kit consisting of a Coriphosphine-O dye and a Biological Calibrator, and software for automated analysis of reticulocytes in whole blood using EPICS® XL™ Flow Cytometry Systems with SYSTEM II™ Software. The system is intended "For In Vitro Diagnostic Use" and allows identification and enumeration of reticulocyte percentage and absolute count.
The reticulocyte count is diagnostically useful in discriminating between normal erythropoiesis. It can be useful in the diagnosis or detection of anemal hemorthaging, hemoglobinopathies and certain nutritional or vitamin deficiencies. Decreased or defective red cell production may result in a lower reticulocyte count such as in aplastic anemias. Elevated reticulocyte counts may be observed in clinical conditions where red cell destruction is increased (for example, hemolytic anemias and hypersplenism) or where there is increased red cell production (for example, erythropoietin drug therapy and a response to treated anemia).
Since the kidneys are a primary source of erythropoietin (a hormone that regulates erythroid development), the reticulosyte count is also affected in individuals with renal disease. In cases of renal atrophy, the reticulocyte count will be decreased. In cases of malignancy or hypersplenism, the reticulocyte count will be elevated.
Reticulocyte counts are also used as an indicator of bone marrow recovery following intensive or a bone marrow transplantation. Increased reticulocyte counts in these patients are indicative of bone marrow regeneration.
