Immunoassay
Reference Interval
Female: < = 14 ng/L
Male: < = 22 ng/L
Delta:
0 HS to 1 HS: < = 2 ng/L
0 HS to 3 HS: < = 5 ng/L
Critical Value:
Female/ Male: > = 52 ng/L
Interpretive Data
Serial high sensitivity troponin measurements within the normal range may still be clinically significant if repeat levels are rapidly increasing. Specifically, a change in high sensitivity troponin level of > = 3 ng/L in the first hour or > = 6 ng/L over the first 3 hours after the initial test may be indicative of myocardial injury. Nonetheless, high sensitivity cardiac troponin results should always be used in conjunction with the patient's clinical presentation.
Sample should not be taken from patients receiving therapy with high biotin doses
(> 5mg/day) until at least 8 hours after the last biotin administration.
Can this test be added to a previous specimen?
Only if collected in green lithium heparin tube within 24 hours.
