Creatine Kinase (CK) Blood Test


* This is not a home test kit. You will need to visit a local lab for testing.


Blood levels of CK rise when your muscle or heart cells are injured. Your doctor may request measurement of CK (along with tests for other substances, particularly the CK-MB form) if you have chest pain to see if you may have had a heart attack.

In the first 4 to 6 hours after a heart attack, CK in blood begins to rise. It reaches its highest level after about 18 to 24 hours, and returns to normal in about 2 to 3 days.

The test for CK can also indicate if your other muscles are damaged.

Recommended For:

Those experiencing muscle weakness, muscle aches, and/or dark urine; Those who have suffered from a muscle injury.

Special Notes:

Avoid exercise before providing blood sample.
