Interpreting the lupus anticoagulant panel can be hard. It becomes easier when you recognize that it is one big mixing study. Hematologist, Dr. Toyosi Onwuemene, helps us with the interpretation.

Mixing studies help us distinguish coagulation factor deficiencies from inhibitors. But how do we interpret the results? Hematologist, Dr. Toyosi Onwuemene, walks us through the interpretation.

So the activated partial thromboplastin time (aPTT) is normal; but the prothrombin time (PT) is prolonged. How do you work it up? Hematologist, Dr. Toyosi Onwuemene, reviews the evaluation.

What do you do when both the prothrombin time (PT) and activated partial thromboplastin time (aPTT) are prolonged? For starters, you think about what information the prolonged aPTT and the PTT give you about the coagulation cascade (Are you feeling anxious yet?). Hematologist, Dr. Toyosi Onwuemene, walks you through the evaluation.

When the activated partial thromboplastin time (aPTT) is prolonged; but the prothrombin time is normal, that narrows down the possibilities to a deficiency or inhibitor of the intrinsic pathway. In this video, hematologist, Dr. Onwuemene walks us through the evaluation.

Anemia is so common that we don’t respect it. We guess at the reason for anemia and hope for the best. In this video, hematologist, Dr. Toyosi Onwuemene, discusses three essential tests for anemia that you should order every time.

The presence of microcytosis may indicate iron deficiency vs. hemoglobinopathy. But before all the tests are back, can you distinguish between the two? Hematologist, Dr. Toyosi Onwuemene, shows us a way to make a quick educated guess.

When you review the complete blood count (CBC), what is the significance of the MCV, MCH, MCHC, RDW, and NRBC? How can you differentiate between them? Hematologist, Dr. Toyosi Onwuemene, introduces us to the CBC’s less popular members.

When the Consult Service is called about a patient with B-symptoms and monocytosis, it is easy to jump immediately to the bone marrow biopsy. Before the bone marrow biopsy, hematologist, Dr. Toyosi Onwuemene, discusses why a broad differential should be considered.
