If you've been told in the past that you cannot wear contact lenses because of an irregular cornea or other problems, you may want to get a second opinion and ask your eye doctor about scleral contact lenses.
Blood enzyme tests. Enzymes are chemicals which help to regulate a number of chemical reactions, and that take place in the body. Blood enzyme tests can be used to measure the levels and activity of certain enzymes. Some blood enzyme tests assess the liver enzymes and others test for damage to the heart. Creatine kinase. Creatine kinase is an enzyme which is produced by the majority of muscle cells.
Cardiac enzyme studies measure the levels of the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT) in the blood. Values and units for reporting the results of cardiac enzyme tests vary considerably. The normal values listed here-called a reference range-are just a guide.
