MessageAbbott I-Stat
Test Code
POCT TROPONIN I
CPT Codes
CPT 84484
Minimum Volume
95 µL (2-3 drops)
Instructions
Collect a green top Lithium heparin tube and place three drops of blood , into the Cartridge well, snap closed, and insert into reader
Transport Temperature
Room Temperature
Specimen Stability
There is no long term storage for specimens. All specimens must be tested within 30 minutes. Arterial specimens should be tested within 10 minutes to avoid samlples being affected by extended exposure to ambient air contamination. Samples for pH, PCO2,
Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
"Anticoagulants such as EDTA, citrate, or oxalate must not
be used for ACT or cTnI testing. Plastic syringes or tubes
are the only collection devices acceptable! Skin puncture
is not acceptable for performing an ACT or cTnI."

Methodology
enzyme-linked immunosorbant assay (ELISA) method.

2. No fungal elements noted
Limitations
The frequency of suppressed results is affected by atmospheric pressure. Suppressed result rates may increase with higher elevations (decreased barometric pressure) and may become persistent if testing is performed at more than 7500 feet above sea level. Where unavailability of results is unacceptable, i-STAT recommends having an alternate test method available.
Reference Range
Less than or equal to 0.034
Clinical Significance
Biochemical cardiac markers, including cTnI, are useful for both the diagnosis of myocardial infarction and the risk stratification that can help guide the choice of therapeutic options.
