What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

Coagulation factor VIII activity and inhibitor panel - Platelet poor plasma by Chromogenic method

Coagulation factor VIII activity & inhibitor panel

This panel contains results for factor VIII activity levels and the presence inhibitors directed against coagulation factor VIII. Factor VIII inhibitors are IgG antibodies that when present can lead to the development of possibly life-threatening hemorrhages. These antibodies most commonly are found in patient with Hemophilia A, elderly patients, postpartum mothers, and autoimmune deficient patients.
