Flow Cytometric Reagents And Accessories.

Page Type
Product Code
Definition
To identify and classify cells or other particles in suspension by their inherent physical properties or associated fluorescent molecules in order to provide information about the distribution or number cells in suspension or their level of protein expression. These characteristics may aid in the diagnosis of conditions such as immunodeficiency and cancer.
Physical State
May include flow cytometers, monoclonal antibodies, lysis reagents, processing reagents, automated processing devices or pipetting devices.
Technical Method
Particles in suspension may be treated with fluorescent conjugated antibodies or fluorogenic compounds followed by interrogation in a flow cytometer that enumerates and characterizes each particle based on its physical and fluorescent characteristics.
Target Area
Peripheral whole blood specimens, lymphoid biopsies, and neoplastic tissues.

CFR § 864.5220 Automated differential cell counter

§ 864.5220 Automated differential cell counter.

(a) Identification. An automated differential cell counter is a device used to identify one or more of the formed elements of the blood. The device may also have the capability to flag, count, or classify immature or abnormal hematopoietic cells of the blood, bone marrow, or other body fluids. These devices may combine an electronic particle counting method, optical method, or a flow cytometric method utilizing monoclonal CD (cluster designation) markers. The device includes accessory CD markers.

(b) Classification. Class II (special controls). The special control for this device is the FDA document entitled “Class II Special Controls Guidance Document: Premarket Notifications for Automated Differential Cell Counters for Immature or Abnormal Blood Cells; Final Guidance for Industry and FDA.”
