What Coagulation Control, normal does
Coagulation control is lyophilised plasma with assigned values for the clotting times it covers, and the normal level demonstrates that the analyzer and reagent together reproduce an expected result in the range most patients fall in. It has one characteristic that distinguishes it from other quality control material: reconstitution matters a great deal. The volume of diluent must be exact and the reconstituted plasma must be allowed to stand and be mixed as the insert directs, because the assay measures a clotting time and anything that alters the concentration alters the time. A control failure on this bench is as often a reconstitution problem as an instrument one.
How Philippine laboratories run it
Run at the frequency the laboratory quality control policy sets and after each reagent lot change, which on a coagulation bench is frequent because reconstituted reagent has a short working life. Philippine laboratories supporting elective surgery should note that a coagulation control failure stops PT reporting and therefore stops theatre lists, so cover for this material is not a back-office concern. It is ordered in step with the abnormal level, and the two should never be allowed to run out of alignment.

Delivered with the other control and calibrator materials for that bench, on the same schedule as Coagulation Control, normal.
Storage and handling
Refrigerated, reconstituted with the exact volume the insert specifies, allowed to stand and mixed as directed.
Buying Coagulation Control, normal in the Philippines
Coagulation Control, normal is supplied for the C2000-2 / C2000-4 and C3100. We deliver it with Coagulation Control, abnormal and PT Reagent, because a run held up waiting on a separate order costs the same shift a stock-out does. Delivery is scheduled against how fast your bench actually gets through it, which for a consumable is set by workload rather than by a calendar. How we plan coagulation supply.
Questions about Coagulation Control, normal
Why do coagulation controls fail so often after reconstitution?
Because the assay measures a clotting time, so anything that changes the concentration of the reconstituted plasma changes the result. An inexact diluent volume, insufficient standing time or inadequate mixing will all produce a failure that looks like an instrument problem. Reconstitution technique is worth checking first when a coagulation control fails.
