Hematology Control

Para 12 Extend is a hematology control with three distinct populations of lymphocytes, mononuclears, and granulocytes. Varying percentages are also offered in the low abnormal, normal, and high abnormal levels to test the accuracy and precision of the reported white cell populations. Values are recovered for all parameters ensuring requirements are met for complete laboratory quality control.

Para 12 Extend is available in plastic cap-pierceable vials which allow for autosampling by an analyzer.

Streck offers STATS®, a free Interlaboratory Quality Control program for our customers.
