ORDERING

SPECIMEN

PROCESSING

RESULTS

This test CANNOT be shared with or added onto other existing orders (e.g., CBC, tacrolimus, HbA1c).

Test Code

SHC TEST CODE LPCH TEST CODE
LABHSTNI LABHSTNI

Specialty

General Chemistry

Synonyms

troponin, tni

Useful For

Used to identify myocardial infarctions.

Clinical Utility

The hs-TnI assay allows for more accurate and precise troponin I results at very low concentrations, thereby shortening the time interval required to identify myocardial injury and permits for the use of an accelerated chest pain algorithm for rapid rule-out/rule-in of acute myocardial infarction (AMI).

CPT Code

84484
Collection Instructions

Collect blood following standard venipuncture collection procedures.

Container Type
Lavender top tube

Specimen Quantity and Stability

VOLUME TEMPERATURE
SPECIMEN TYPE CONTAINER REQUESTED (OPTIMAL) MINIMUM (PEDIATRIC) ROOM TEMP REFRIGERATED FROZEN
Whole blood Lavender top tube containing K2EDTA 3 mL 1 mL 8 hours Unacceptable Unacceptable
Causes for Rejection

Only K2EDTA (lavender-top) tubes are acceptable. No other blood collection tube type is acceptable. The test WILL BE CANCELLED if collected in other blood collection tubes like red-top, mint-top (PST), gold-top (SST) tubes. Hs-TnI test CANNOT be shared with or added onto other existing orders (e.g., CBC, tacrolimus, HbA1c).
