The document describes a control sample for flow cytometry and does not mention any AI or ML components.
No.
The device is described as a control sample for evaluating the binding of monoclonal antibody using flow cytometry in a clinical laboratory setting, and not for direct therapeutic intervention on a patient.
No
This device is described as a control sample/specimen used for evaluating and validating the binding of monoclonal antibodies in flow cytometry, specifically for CD34 stem cell enumeration. It is a "procedural control" and "control material," not a device that directly diagnoses a patient's condition.
No
The device description clearly states it is a stabilized suspension of human placental blood packaged in glass 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 is a "control sample for evaluating the binding of monoclonal antibody using flow cytometry" and is used by a "clinical laboratory performing quantitative stem cell analysis" as a "control specimen for verifying the measurement process." This aligns with the definition of an IVD, which is used to examine specimens derived from the human body to provide information for diagnostic purposes. While this specific device is a control, it is used in conjunction with diagnostic tests (CD 34 stem cell enumeration) to ensure their accuracy.
- Device Description: It is a "stabilized suspension of human placental blood containing red blood cells and white blood cells," which are biological specimens.
- Intended User / Care Setting: It is intended for use in a "Clinical laboratory," which is a typical setting for IVD testing.
- Performance Studies: The summary of performance studies describes testing related to stability and reproducibility, which are standard evaluations for IVD control materials.
- Predicate Device: The mention of a predicate device (CD Chex Plus RBC) further suggests it falls under the regulatory framework for IVDs.
While it is a control and not a test that directly diagnoses a condition, its function is to ensure the reliability and accuracy of a diagnostic test (CD 34 stem cell enumeration). Therefore, it is considered an IVD control.

Intended Use / Indications for Use
CD Chex CD 34 is designed as a control sample for evaluating the binding of monoclonal antibody using flow cytometry. It is intended to be used with Becton Dickinson ProCount Progenitor Cell enumeration kit and with systems using ISHAGE protocol for CD 34 stem cell marker.
A clinical laboratory performing quantitative stem cell analysis needs a control specimen for verifying the measurement process. CD Chex CD 34 is such a specimen. It consists of stabilized placental blood containing a population of CD 34 positive stem cells. It is used as a procedural control for monitoring monoclonal antibody binding in flow cytometry methods. Users of Becton Dickinson ProCount Progenitor Cell Enumeration Kit or ISHAGE protocol can validate their CD 34 results by controlling the procedure with CD Chex CD 34.

Description: CD Chex CD 34 is a stabilized suspension of human placental blood
containing red blood cells and white blood cells. It is packaged in glass
vials containing 1 ml of product. Closures are polyproplylene screw
caps. The package contains two vials of a single concentration and an
assay sheet stating the expected values.
Intended Use: CD Chex CD 34 is designed as a control sample for evaluating
the binding of monoclonal antibody using flow cytometry. It is intended
to be used with Becton Dickinson ProCount Progenitor Cell enumeration
kit and with systems using ISHAGE protocol for CD 34 stem cell marker.
Comparison with Predicate Device: CD Chex Plus RBC is a an immunophenotyping
control for several clinically useful cell surface markers. CD Chex CD 34
is assayed only for the CD 34 marker. They are both procedural controls
for monitoring reagents and the instrument.
Discussion of Tests and Test Results: Studies were conducted on three(3) Pilot lots
to assess the performance of CD Chex CD 34. These were:
1.) Long term stability, 2) Open vial stability, 3) Within-run and Site to
Site reproducibility.
The studies verified that the product performed to specifications and is
useful as a control material for CD 34 measurement procedures.
Conclusions Drawn from Tests: CD Chex CD 34 is an effective control for CD 34
immunophenotyping when used according to instructions in the package
insert. Extensive raw material testing assures the user of a safe product.
