Blood enzyme testing come in a variety of forms.
When a person has muscle damage, particularly damage to the heart muscle, blood levels of troponin increase. Chemicals called enzymes to aid in regulating chemical reactions in the body. In addition, when the heart (cardiac) muscle is damaged, an enzyme called CK-MB is released into the blood. Blood enzyme test may be used to look for heart attacks. Tests for heart attacks include those for troponin and creatine kinase (CK). High blood levels of CK-MB can indicate that you've had a heart attack.
According to the American Board of Internal Medicine, reference ranges for the troponin test are expressed in nanograms per milliliter (ng/mL) as follows:
Troponin I: 0 to 0.04 ng/mL
Troponin T: 0 to 0.01 ng/mL
The range of acceptable reference values for serum CK-MB is three to five percent (percentage of total CK) or 5 to 25 IU/L.

Two examples of such medications are heparin and warfarin.
Doctors frequently order blood clotting tests (coagulation tests) such as:
D-dimer test
Detects D-dimer in the blood (a protein fragment formed in the body when a blood clot dissolves)
A normal D-dimer is considered 0.50
As D-dimer is a screening test, a positive D-dimer is a positive screen. An INR is a calculation based on PT test results.
PT: 11 to 13.5 seconds
INR: 0.8 to 1.1
Activated partial thromboplastin time test
PT test determines how long it takes for a blood clot to form in a blood sample. Blood clotting tests look for proteins in your blood that affect how your blood clots. An INR is a calculation based on PT test results.
A normal range is between 21 and 35 seconds.Levels that are abnormally high or low could indicate that you're in danger of bleeding or getting blood clots in your blood vessels. There is no critical level for a D-dimer.
Prothrombin time (PT)/INR test
PT test determines how long it takes for a blood clot to form in a blood sample. Blood clotting tests are also used to track the health of people who take medications to reduce their risk of blood clots.
