What lab tests are essential to be drawn STAT for a patient experiencing postpartum hemorrhage?

In the context of postpartum hemorrhage, it is crucial to quickly determine the patient's blood type and ensure the availability of compatible blood for potential transfusion. Therefore, drawing a type and cross-match is essential. This allows for a rapid response in the event the patient requires blood transfusions due to excessive blood loss.

Measuring hemoglobin levels is also vital, as it helps assess the severity of the hemorrhage and guides treatment decisions. Monitoring platelet counts can be important, particularly if there are concerns about coagulopathy or platelet disorders, which can complicate the management of bleeding.

Other lab tests, such as glucose and electrolytes, while useful in some situations, do not address the immediate concerns of hemorrhage management. A complete metabolic panel and thyroid function tests might provide additional information but are not critical in the acute context of postpartum hemorrhage. Similarly, coagulation studies and liver function tests may have their place in evaluating underlying causes of bleeding or future management but are not as immediately essential as the core tests focusing on blood type and hemoglobin levels in this scenario.
