Pima™ CD4

Pima cartridge



The Pima CD4 cartridge is a unique and breakthrough technology in the enumeration of T-helper cells in whole blood samples. Requiring only 25μL of capillary whole blood and with all test reagents sealed within the disposable cartridge, obtaining a CD4 count is now easier than ever.

Insertion of the Pima CD4 cartridge into the Pima analyser automatically begins the testing process providing you with a direct CD4 measurement in 20 minutes.
