Please inactivate test code TROP at that time. Specimen requirements remain the same (one PST green lithium heparin tube) .  \nThe new reference range is ≤15 pg/ml for females and ≤20 pg/ml for males; results above these values indicate the possibility of myocardial infarction and require additional patient evaluation. An elevated and actionable value of hs TnI is > 100 pg/mL for males and > 75 pg/mL for females, and indicates an increased likelihood of myocardial damage.  \nIn addition to the troponin values, a Delta value (change from previous result, represented by Δ) will be calculated and presented as a positive or negative change measured in pg/mL. For evaluation of chest pain patients, an initial (time 0) and a repeat (3 hour) troponin value are indicated to assess the Delta value. Patients presenting with a high or critical Delta value at the 3 hour troponin repeat indicates ongoing cardiac damage. Suggested patient management algorithms can be found here: hs Troponin I Interpretation and  Patient Management Algorithms  \nThe troponin values should be evaluated in the context of the patient’s Heart Score to aid in clinical management (See Tables 1 and 2) .  \nNote: Elevations of Troponin-I may be seen in congestive heart failure, pulmonary embolism, hypertension, sustained tachycardia, myocarditis/pericarditis, renal failure, cocaine abuse and hypothyroidism\". The assay should not be used to evaluate patients younger than 21 of age (e.g. children, teens, etc). These patients will typically present with elevated but unchanging troponin values over time.  \nOrderCode OrderName ResultCode ResultName ResultUnits LOINC CPT  \n\n| \u003Cbr>HSTROP | CARDIAC TROPONIN I | HSCTN | HIGH SENSITIVITY CARDIAC TROPONIN | ng/L | 89579-7 | 84484 |\n| --- | --- | --- | --- | --- | --- | --- |\n| HSTROP | CARDIAC TROPONIN I | DELTA | DELTA | ng/L |  |  |\n\nIf you have questions or concerns about this change, please contact Dr. Sam Pirruccello (phone: 402-559-7707  \nor 402-763-3157, pager: 402-888-1640, e-mail: [spirrucc@unmc.edu](spirrucc@unmc.edu)) .  \n24/7 Client Services 1-800-334-0459  \nTable 1.
