Question: 1 / 400

What common lab tests are performed during trauma evaluation?

CBC, coagulation profile, and basic metabolic panel

The most relevant and commonly performed lab tests during trauma evaluation include a complete blood count (CBC), a coagulation profile, and a basic metabolic panel.

The CBC provides essential information about the patient's hemoglobin levels, white blood cell count, and platelet count, all of which can indicate blood loss or infection. The coagulation profile is critical in assessing the patient's ability to clot, which is particularly important in trauma cases where bleeding may be a significant concern. The basic metabolic panel checks for electrolyte levels, kidney function, and blood glucose, providing a comprehensive view of the patient's metabolic state, which can be affected by trauma.

These tests are essential in forming an initial evaluation and guiding further medical management, making them standard in trauma settings.
