If you ve had a heart attack both ck mb and the ratio of ck mb. Following a heart attack these enzymes will increase.
You may need to have repeated tests to see if you ve had a heart attack.
Ck ck mb ratio calculator. The ck mb lab test is part of a group of tests that examine cardiac enzymes. A high ck with a very low relative index suggests that other muscles were damaged. Levels of ck mb do not rise in your blood within the first 4 to 6 hours after a heart attack.
100 x ck mb in ug l ck in u l. Additionally the ck mb to total ck ratio was markedly higher in advanced stage malignancy than in early stage 1 37 0 26 vs. 1 29 0 31 p 0 014 and significantly higher in liver metastasis.
Ck mb test also known as creatine kinase mb test plays a significant role in detecting whether you have a heart attack a second or subsequent heart attack or not. If ck mb is elevated and the ratio of ck mb to total ck relative index is more than 2 5 3 then it is likely that the heart was damaged. This ratio indicates how much muscle damage is related specifically to the heart muscle as opposed to other muscles in the body.
A ratio of less than 3 is. Regenstrief loinc part description lp15513 2 creatine kinase. You may need to have repeated tests to see if you ve had a heart attack.
A high ck with a relative index below this value suggests that skeletal muscles were. Version 2 68 49136 5creatine kinase mb creatine kinase total ratio in serum or plasmaactive term description sometimes called ck mb mass total ck activity ratio this parameter is now often referred to as the relative ck mb index. The relative index calculated by the ratio of ck mb mass to total ck can assist in differentiating false positive elevations of ck mb arising from skeletal muscle.
If you ve had a heart attack both ck mb and the ratio of ck. Levels of ck mb do not rise in your blood within the first 4 to 6 hours after a heart attack. If the ratio of ck mb to total ck relative index is more than 2 5 3 the heart is the likely muscle damaged.
Creatine kinase ck is a dimeric enzyme occurring in four different forms. The ck mb ratio is calculated through a simple mathematical equation. A mitochondrial isoenzyme and the cytosolic isoenzymes ck mm skeletal muscle type ck bb brain type and ck mb myocardial type.
It is also used to distinguish between skeletal muscle and heart muscle damage. The parameter is now reported as percent.
