You may have other blood tests to measure how quickly your blood clots. A blood test called activated partial thromboplastin time (APTT) is often done as a backup to the results of the ACT test. What do my test results mean? Test results may vary depending on your age, gender, health history, and other things.

The aPTT is 1 of several blood coagulation tests. It measures how long it takes your blood to form a clot. Normally, when 1 of your blood vessels is damaged, proteins in your blood called clotting factors come together in a certain order to form blood clots and quickly stop bleeding.

Thrombin time is one of several tests that check if your blood is clotting normally. Blood clotting (coagulation) is needed to help stop bleeding when you have an injury. Proteins in the blood called clotting factors help specific blood cells stop bleeding.

point and measuring the time it takes for fibrin for-mation. The usefulness of a clotting time for drug monitoring depends on where along the cascade the reaction is started as well as the concentration of reagent used to push the reaction forward. A typical activated clotting time (ACT) uses kaolin, glass, or sim-

Cardiac Biomarkers (Blood) Does this test have other names? CK, CK-MB, cardiac troponin T, troponin I, myoglobin, cardiac enzymes . What is this test?

Screening tests of clotting times. These are called prothrombin time (PT) and activated partial thromboplastin time (aPTT) Mixing studies with certain clotting factors added. This is done to see if the clotting time (aPTT) corrects. This clarifies if there is a deficiency.

Your healthcare provider may order different types of blood-clotting tests. These may include: Activated partial thromboplastin time (aPTT) test. This shows the activity of several substances involved in blood clotting. Prothrombin time (PT) test.) This measures how long it takes your blood to form a clot. Platelet count.

Your healthcare provider may ask you to provide a sample at a specific time of day, such as first thing in the morning. Or you may collect a sample at random. For this test, you may also need to collect all the urine you make over a certain period, such as 24 hours. For this sample, you empty your bladder completely first thing in the morning ...
