Our September 2021 Quick Question attracted only 14 responses, perhaps reflecting the minimal communication between the central laboratory and the anesthesiology service in most operating rooms. Our question was "What is the favorite near-patient viscoelastic test of US anesthesiologists?" Here are your answers: Rotational thromboelastometry [ROTEM ]: 14% [2] Resonance sonorheometry [Quantra]: 7% [1] Activated clotting time [ACT ]: 0% Thromboelastography [TEG ]: 79% [11]

From Deanna Miller, Children's Hospital of Alabama. Do you have any good references for diluted thrombin and utilization of this test?  What dilution is best? 1:1 or 1:3?

From Alan Neal, Pathlab, NZ. Just wanted a private conversation about the January 11, 2018 Fritsma Factor entry, "POC and Plasma-Based PT/INRs." I do not agree with the comments made within this article and challenge the logic used. Essentially, if monitoring an enzymatic pathway such as coagulation, with the 'detector' being used is fibrinogen to fibrin, then that rate of reaction will be dependent on the substrate concentration, i. e., fibrinogen, and the sensitivity of the analyser to detect the end point. So if no or reduced fibrinogen or dysfibrinogen, then reduced Vmax and hence PT/INR will be more prolonged than test system using a clot based end point detection.
