Final answer:
The normal range for cardiac troponin T is generally considered to be less than 0.04 ng/mL. Elevated levels may indicate heart muscle damage or injury.
Step-by-step explanation:
The normal range for cardiac troponin T, a protein found in the heart muscle, is generally considered to be less than 0.04 ng/mL. Elevated levels of cardiac troponin T in the blood indicate heart muscle damage or injury, which can be a sign of a heart attack or other cardiac condition.
For example, if a person has a Troponin T level of 0.1 ng/mL, it is considered to be elevated and may indicate heart muscle damage. On the other hand, a Troponin T level of 0.02 ng/mL would be within the normal range.
