CPK blood test range

If you have undergone the CPK blood test the laboratory may have provided you with a set of values. Any decent laboratory should provide the range of normal values with it. But sometimes they may not. Then you may be wondering before going to a doctor “what is the CPK blood test range? “ For you reference herewith I am providing you with the CPK blood test range. Blood please remember CPK normal values are always laboratory specific so there can be a slight deviation of the normal values I have provided here from the normal values of your laboratory.

Creatine kinase (CPK)

• Female 24-170 U/L
• Male 20-260 U/L
• CK-MB fraction

There is another thing. Any value outside the normal range is not necessarily abnormal. Any value outside this range has a higher probability to be abnormal. So some values outside the normal range can be perfectly normal for some people.

INR test PT/INR test

INR test
If you are currently on warfarin your doctor may request for a PT/INT test or you may see one of your relatives getting done a PT/INR test. But what is it? You may wonder. Warfarin is an anticoagulant mainly given to patients who at increased risk of the development of intravascular blood clots. For this discussion we will restrict our patient category to patients with prosthetic heart valves. Patient with prosthetic heart valves at increased risk of development of blood clots. These clots can cause various catastrophic events. E.g.: strokes, Myocardial infarctions, Peripheral vascular disease and etc. To reduce this an anticoagulant is given. But this has side effects. Major side effect of our interest is excessive bleeding. To balance this risk and benefit anticoaguability of the warfarin PT/INT test is used. Actually the PT part is the test. PT is the abbreviation for prothrombin time. INR means international normalized ratio. Due to diversity of the chemical manufacturers different laboratories get different result for the PT test. But the manufacturer of that particular chemical compound gives the data to convert it to the universally accepted INR. This value doesn’t change from the laboratory. So is a single patient’s blood checked by two laboratories the INR test value should be equal.
