What This Entry Means
The slug appears to merge "coronary," a general reference to the heart's blood vessels, with "Act FAST," a public stroke-awareness mnemonic. The "deprecated" prefix signals that this item has been retired and is not an active test.
Why It Is Not a Real Lab Test
"Act FAST" is a symptom-recognition tool for stroke (Face drooping, Arm weakness, Speech difficulty, Time to call emergency services), not a blood or laboratory measurement. Combining it with "coronary artery" does not map to a recognized analyte, specimen, or method.
Method and Specimen Ambiguity
No specimen type, measurement unit, or analytical method can be reliably decoded from this slug. Because the abbreviation is ambiguous and deprecated, no specific specimen or methodology should be assumed.
Safe Interpretation Guidance
If you encounter this term, treat it as an invalid or retired code rather than a clinical result. Do not use it to make health decisions; consult a qualified healthcare professional or laboratory for any actual test information.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinically, this slug has no standing as a laboratory test and carries no diagnostic significance. Coronary artery health is assessed through other means such as lipid panels, imaging, and cardiac markers, while stroke symptoms warrant emergency evaluation, not a lab result.
