The device description and performance studies focus on the stability and reproducibility of a control material for reticulocyte counting, with no mention of AI or ML technologies.
No
The device is described as an assayed control for evaluating the accuracy and precision of reticulocyte counting methods, not for treating a condition or disease.
No
The device is described as an "assayed control" used for evaluating the accuracy and precision of reticulocyte counting methods, not for directly diagnosing medical conditions in patients.
No
The device description clearly states it is a suspension of stabilized human red blood cells and simulated human reticulocytes packaged in plastic vials, indicating it is a physical control material, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for "evaluating the accuracy and precision of automated, semi-automated and manual methods of reticulocyte counting." This is a diagnostic purpose, as it's used to assess the performance of tests that measure a component of blood.
- Device Description: The device is a "suspension of stabilized human red blood cells and simulated human reticulocytes." This is a biological material designed to be used in vitro (outside the body) for testing purposes.
- Context: The device is a "control" for reticulocyte counting. Controls are a fundamental part of IVD testing, used to ensure the reliability and accuracy of the test method.
- Predicate Device: The predicate device listed (Retic-Chex® Linearity) is also an IVD control product, further supporting the classification of this device as an IVD.
Therefore, based on its intended use, composition, and function as a control for a diagnostic test, this device fits the definition of an In Vitro Diagnostic.

Device Description
Retic-Chex for Cell-Dyn is a suspension of stabilized human red blood cells and simulated human reticulocytes packaged in plastic vials containing 1.0ml volumes. The device consists of two levels of reticulocyte percentage range. Control I reticulocyte percent range will be 1.5 - 2.0. Control II reticulocyte percent range will be 3.9 - 5.8. Closures are injection molded polypropylene screw-top caps. The vials are packaged in vacuum molded clam-shell box.

§ 864.8625 Hematology quality control mixture.
(a)
Identification. A hematology quality control mixture is a device used to ascertain the accuracy and precision of manual, semiautomated, and automated determinations of cell parameters such as white cell count (WBC), red cell count (RBC), platelet count (PLT), hemoglobin, hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC).(b)
Classification. Class II (special controls). Except when intended for use in blood components, the device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.

Description:
Retic-Chex for Cell-Dyn is a suspension of stabilized human red blood cells and simulated human reticulocytes packaged in plastic vials containing 1.0ml volumes. The device consists of two levels of reticulocyte percentage range. Control I reticulocyte percent range will be 1.5 - 2.0. Control II reticulocyte percent range will be 3.9 - 5.8. Closures are injection molded polypropylene screw-top caps. The vials are packaged in vacuum molded clam-shell box.
Intended Use:
Retic-Chex for Cell-Dyn is an assayed control for evaluating the accuracy and precision of automated, semi-automated, and manual methods of reticulocyte counting. It is designed for use on the following automated reticulocyte counting. It is designed for use on the following reticulocyte analyzers: Abbott Cell-Dyn 4000, 3700, 3500, and 3200,
Comparison with Predicate Device:
Like Retic-Chex Linearity, Retic-Chex for Cell-Dyn is a multi-level device intended for validation of reticulocyte analysis on a variety of automated hematology instruments. Both devices contain stabilized human red blood cells and simulated human reticulocytes, which properly mimic human whole blood on the intended use analyzers.
Testing Performed:
Three studies of Retic-Chex for Cell-Dyn were conducted: 1) Closed Vial Stability: 2) Open Vial Stability; and 3) Manual Count Closed Vial Stability. Study results showed Retic-Chex for Cell-Dyn to be consistently reproducible and stable for the entire product dating.
Conclusions Drawn from the Tests:
Study results show Retic-Chex for Cell-Dyn to be consistently reproducible, substantially equivalent to the predicate product, and stable for the entire product dating. Retic-Chex for Cell-Dyn is a safe and effective product, which fulfills its intended use when used as instructed in the product package insert.

In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
