Intended Use
The RAMP Reader is a general use fluorometer that analyzes results produced by immunoassays that use a fluorophore having an excitation wavelength at 560 nm and an emission wavelength of 610 nm. The RAMP™ Myoglobin Assay is an immunochromatographic test for the quantitative determination of myoglobin in human EDTA whole blood, using the RAMP Reader.
Device Description
The RAMP Myoglobin Assay is an immunochromatographic test for the quantitative determination of myoglobin in human EDTA whole blood, using the RAMP Reader. Diluted EDTA whole blood is applied into the sample well of the Test Cartridge. The red blood cells are retained in the sample pad, and the separated plasma migrates along a strip, through a contact zone where it interacts with fluorescent latex particles. Latex (test) particles, coated with mouse monoclonal anti-myoglobin antibodies bind to myoglobin in the sample. The sample moves by capillary action towards the end of the strip. As the sample migrates to the detection zone, myoglobin anti-myoglobin particles are immobilized at the detection zone. and additional particles are immobilized at the internal control zone. The RAMP Reader then measures the amount of fluorescence emitted by the complexes bound at the detection zone and at the internal control zone. Using a ratio between the two fluorescence values, a quantitative reading is calculated.
More Information

No
The description details a standard immunochromatographic assay read by a fluorometer, with calculations based on fluorescence ratios. There is no mention of AI/ML terms, image processing, or training/test data sets typically associated with AI/ML algorithms.

No
The device is used for diagnostic purposes by quantitative determination of myoglobin, not for treatment or therapy.

Yes

Explanation: The device is used for the quantitative determination of myoglobin in human EDTA whole blood, which is a clinical measurement used for diagnostic purposes, such as in suspected acute myocardial infarct (AMI).

No

The device description explicitly states it uses a "RAMP Reader," which is described as a "general use fluorometer." This is a hardware component used to analyze the results of the immunoassay. The device is not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the RAMP Myoglobin Assay is for the "quantitative determination of myoglobin in human EDTA whole blood". This is a test performed in vitro (outside the body) on a biological sample (whole blood) to provide information about a patient's health status (myoglobin levels).
  • Device Description: The description details a process of analyzing a biological sample (diluted EDTA whole blood) using an immunochromatographic test. This is a common method used in IVD devices.
  • Performance Characteristics: The document includes sections on "PERFORMANCE CHARACTERISTICS" and "CLINICAL PERFORMANCE," which are standard requirements for demonstrating the analytical and clinical validity of an IVD device. These sections describe studies performed on biological samples (standards, bovine calf serum, healthy individuals, patients suspected of AMI).
  • Predicate Devices: The mention of predicate devices (K973126 Triage Cardiac Panel®; Myoglobin Assay; K000196 ACCESS® Myoglobin Assay) which are known IVD devices, further supports that this device falls under the IVD category.

The RAMP Reader itself is described as a "general use fluorometer," but its use in conjunction with the RAMP Myoglobin Assay, as described, makes the system (RAMP Reader + RAMP Myoglobin Assay) function as an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

PERFORMANCE CHARACTERISTICS
PRECISION: The intra-assay and the inter-assay precision of the RAMP Myoglobin Assay were determined by one operator assaying duplicates of each standard (50, 100 and 200 ng/mL myoglobin standards) twice each day over 10 days. The mean, standard deviation and % CV were calculated for the predicted myoglobin at each concentration. Within run precision ranged between 13.0 to 6.5%. Between run precision ranged from 9.1 to 13.8%. Total precision ranged from 10.6 to 14.3%.

LINEARITY: Discrete myoglobin antigen concentrations of 10, 50, 75, 100, 150, 200 and 350 ng/mL were prepared in bovine calf serum. The linearity is determined by assaying five replicates of each standard. The mean, standard deviation and % CV were calculated for the predicted myoglobin at each concentration. Linear regression analysis of expected myoglobin concentration versus actual myoglobin concentration results with an R = 0.998 and a slope of 1.07 with an offset of 1.143.

HOOK EFFECT: There is no high dose hook effect in the RAMP Myoglobin Assay up to the highest level tested (8000 ng/mL myoglobin).

ANALYTICAL SENSITIVITY: The lower limit of detection (LLD) is defined as the analyte concentration corresponding to the mean (n=20) plus 2 standard deviations of the zero. The LLD is 2.36 na/mL myoalobin levels in excess of 400 ng/mL are reported as greater than (>) 400 ng/mL.

ANALYTICAL SPECIFICITY: Samples containing rheumatoid factor at levels greater than 1300 Rf IU/mL may interfere with the test and cause erroneous results. If this occurs, another specimen should be obtained and tested by an alternate method.

INTERFERENCE: Potentially interfering substances were evaluated by spiking different concentrations of interferents in blood with 100 ng/mL of myoglobin added. Different blood samples were used for each interferent. Interference was evaluated by calculating the myoglobin concentration of interferent-spiked blood, expressed as a percentage of the myoglobin concentration of the unspiked (no interferent) blood sample. No evidence of crossreactivity or interference was observed for hemoglobin (Hb), triglyceride, bilirubin, cholesterol, or coumidin at levels exceeding the highest expected physiological concentration of up to 2000 mg/dL, 3000mg/dL, 60 mg/dL, 2000 mg/dL, and 200 ug/mL, respectively. No trend was observed in the myoglobin predictions as the concentration of interferent was increased.

CLINICAL PERFORMANCE
EXPECTED VALUES: Whole blood samples from 196 healthy individuals, (92 males and 104 females) were assayed. The lower (LLN) and upper (ULN) limits for normal range were defined as the 5" and 95" percentile values, respectively. The normal range of the RAMP Myoglobin Assay was found to be from 19.15 ng/mL to 99.3 ng/mL in the normal population studied. Each laboratory should establish its own expected values.

PRECISION STUDY: Of 179 subjects tested in duplicate, 77 were normal individuals (40 males and 37 females) and 102 were suspected of acute myocardial infarct (AMI) based on the individual hospital criteria (63 males and 39 females). The samples were selected randomly from those obtained during the Method Comparison Study. The samples were stored refrigerated for up to five days between analyses. Data were winsorized (ACCESS values>400) to adjust for differing reportable ranges between the methods and two outliers excluded.

METHOD COMPARISON: Of the 415 subjects compared. 196 were normal individuals (92 males and 104 females) and 219 were patients suspected of AMI based on the individual hospital criteria (131 males and 88 females). An EDTA whole blood sample was obtained for each of these subjects. These samples were tested in RAMP Myoglobin Assay and results compared to those obtained with the Beckman ACCESS Myoglobin Assay. Data were winsorized (ACCESS results >400) to adjust for differing reportable ranges between the methods and three outliers excluded. These results are comparable to correlations of the Biosite Triage Myoglobin Assay verses other clinical analyzers, (N=112) 1.25x+38.8; = 943 and (N=108) 1.31x+17.0; r=.877.

4. Description of the Device:

The RAMP Myoglobin Assay is an immunochromatographic test for the quantitative determination of myoglobin in human EDTA whole blood, using the RAMP Reader.

Diluted EDTA whole blood is applied into the sample well of the Test Cartridge. The red blood cells are retained in the sample pad, and the separated plasma migrates along a strip, through a contact zone where it interacts with fluorescent latex particles. Latex (test) particles, coated with mouse monoclonal anti-myoglobin antibodies bind to myoglobin in the sample.

The sample moves by capillary action towards the end of the strip. As the sample migrates to the detection zone, myoglobin anti-myoglobin particles are immobilized at the detection zone. and additional particles are immobilized at the internal control zone.

The RAMP Reader then measures the amount of fluorescence emitted by the complexes bound at the detection zone and at the internal control zone. Using a ratio between the two fluorescence values, a quantitative reading is calculated.

Comparison of Technological Characteristics ട്.

The RAMP Myoglobin Assay, Triage Cardiac Panel - Myoglobin; and ACCESS Myoglobin Assay are for the quantitative measurement of myoglobin in human whole blood (RAMP and Triage) or plasma (Triage and ACCESS). All three immunoassays utilize the binding of myoglobin to specific antibodies and utilize light in their respective detection systems. Both the RAMP and Triage assays measure light production from a fluorescence reaction using a fluorometer while the ACCESS Test measures light production from a chemiluminescent reaction using a luminometer. Both the RAMP Myoglobin and the Triage Cardiac Panel -Myoglobin are quantitative immunochromatographic tests, whereas the ACCESS Myoglobin test is an enzyme immunoassay.
