CBC / Hematology
Also known as: PTT, intrinsic pathway coagulation factor profile
No common urgent flag from this test alone
This test checks how fast your blood clots. It looks at special proteins in your blood that help it clot.
Your doctor orders this test for a few reasons. They might want to find out why you have bleeding or bruises that don't make sense. They also use it to check medicines that thin your blood, like heparin. Sometimes, they order it to see if you have any blood clotting problems before you have an operation.
Reference ranges for aPTT tests can vary by laboratory and may depend on factors like age, sex, and specific clinical conditions. Your doctor will interpret your results in context.
