💐Mixing Test💐 💐The mixing test is used to evaluate whether a prolonged clotting time is due to a coagulation factor deficiency or the presence of an inhibitor. 🍁Principles🍁 🔸The mixing study involves combining patient plasma with normal pooled plasma (NPP) and measuring the clotting time, which was initially prolonged. 🔸In factor deficiency: NPP provides sufficient clotting factors to compensate for the deficiency, resulting in correction of the clotting time toward normal. 🔸In the prese
