Monitoring specific biomarkers during blood tests, such as Creatine Kinase (CK), which can provide valuable insights into your muscle health, allows for a better understanding of your overall health and wellbeing.
The role of CK in maintaining proper muscle function should be understood, and in this article, we will explore CK in depth, including what it is, why it is important, and how to monitor it, to ensure that you’re taking the best possible care.
Types of Creatine Kinase
There are three main types of Creatine Kinase enzymes, the majority that is found in your blood comes from your skeletal muscles.
- CK-MM: Skeletal Muscles
- CK-MB: Heart Muscle
- CK-BB: Brain Tissue
Risks of Low Creatine Kinase Levels:
Reduced CK levels can be a cause for concern, as low levels of Creatine Kinase can be a sign of an underlying condition, such as a muscle or nerve disorder.
What causes low levels?
Because CK is in proportion to your total muscle mass, individuals who are older, or are unable to move as frequently, will have a lesser amount, those with autoimmune disorders can also suffer from reduced CK levels.
Managing Creatine Kinase Levels
What are normal CK levels?
Normal ranges in adults can vary due to several factors such as sex, ethnicity, and the amount of physical activity completed.
The normal level of Creatine Kinase approximately ranges between:
- Women: 25-200 U/L
- Men: 40-320 U/L
We offer blood tests such as a Sports Performance Blood Test, that measures Creatine Kinase alongside other markers, more related tests are available below.
Are Creatinine and Creatine Kinase related?
While both Creatinine and Creatine Kinase are related to the functions of muscle and metabolism, they are not directly related to each other. Creatinine is a waste product of Creatine, a molecule that helps to supply energy to the muscles during exercise. Therefore, Creatinine is produced by a breakdown of Creatine in the muscles and is removed by the kidneys.
Whereas Creatine Kinase is an enzyme, found in muscle tissue, that is responsible for the breakdown of creatine phosphate to produce energy during muscle contraction. Elevated levels of CK in the blood can be an indication of muscle damage, injury, or certain medical conditions.
Creatinine and CK are also measured differently, and have separate reference ranges, Creatinine is measured in blood or urine tests, while CK is typically measured through a blood test.
