Creatine Kinase (CK)
What is analysed?
Creatine Kinase (CK) analysis involves measuring the levels of CK enzyme in the blood to assess muscle damage or heart-related conditions.
What does the result mean?
The result indicates the level of CK enzyme in the bloodstream. Elevated CK levels may suggest muscle injury, heart attack, or other medical conditions.
Why undergo the analysis?
CK analysis is performed to diagnose muscle damage, monitor heart health, evaluate the effectiveness of treatment in conditions like heart attacks or muscular dystrophy, and assess adverse effects of certain medications.
When to undergo the analysis?
CK analysis may be recommended when there are symptoms suggestive of muscle injury, heart problems, or conditions affecting CK levels. It is also routinely performed in certain medical assessments.
What sample is required?
A blood sample is required for CK analysis.
Is any prior preparation necessary?
No specific preparation is usually necessary before CK analysis. However, patients should inform their healthcare provider about any medications they are taking, as some drugs may affect CK levels.
How is it used?
CK levels are used to diagnose and monitor muscle damage or heart-related conditions. The results help healthcare providers determine appropriate treatment and management strategies.
What are the normal values?
Normal CK levels vary depending on factors such as age, gender, and muscle mass. In adults, normal CK levels typically range from 22 to 198 international units per litre (IU/L).
Creatine Kinase (CK) levels reference table
| CK Level (IU/L) | Interpretation |
| Less than 22 | Generally considered within normal range |
| 22 - 198 | Normal range for adults |
| Above 198 | Elevated CK levels, suggestive of muscle injury, heart problems, or other conditions |
This table provides a reference range for CK levels, aiding healthcare professionals in interpreting CK test results accurately.
What do altered values signify?
Elevated CK levels may indicate muscle injury, heart attack, muscle disorders, or other medical conditions. Lower-than-normal CK levels are less common and may also have diagnostic significance.
