Activated Partial Thromboplastin Time (aPTT) Blood Test
This test investigates a marker or pathway involved in blood clotting. Depending on the specific assay, it may support assessment of coagulation or investigation of a possible bleeding or clotting disorder.
Results may be affected by medicines, recent illness, and other factors. They should be interpreted by a healthcare professional alongside clinical history and related coagulation tests.
Please confirm the required specimen, any medication-related instructions, and turnaround time with the laboratory before collection.
