Streck, La Vista, Neb, introduces Cell-Chex, a manual spinal and body fluid control.
It includes calcium pyrophosphate dihydrate (CPPD) crystals along with distinct white blood cell and red blood cell populations for manual cell counts.
When stained in the same manner as a patient sample, the white blood cells can be differentiated.
The multilevel control is assayed for manual cell counts, the five-part white blood cell differential, and the two-part polymorphonuclear and mononuclear differential.
CPPD crystals are present in Level 1-CC, urate crystals are present in L1-UC, and Level 2 has no crystals. Both urate and CPPD crystals are easily identified and do not interfere with cell counting.
Cell-Chex offers a 6-month closed-vial stability and 30-day open-vial stability when stored at 2° to 10°C.
