What is troponin stat test?
A troponin test measures the levels of troponin T or troponin I proteins in the blood. These proteins are released when the heart muscle has been damaged, such as occurs with a heart attack. The more damage there is to the heart, the greater the amount of troponin T and I there will be in the blood.
What is high specificity troponin assay?
High-sensitivity (hs) cardiac troponin (cTn) assays expedite the evaluation of patients with possible acute coronary syndromes (ACS) in the emergency department. Rapid screening protocols with hscTn have been proposed for patients for whom ruling-in or ruling-out acute myocardial infarction (AMI) is the primary issue.
What’s the normal troponin level?
The normal levels of troponin in the blood are very low. Usual results are 0 to 0.04 nanograms per milliliter. Such low levels are difficult to measure accurately with standard testing.
What is a positive troponin I level?
The level of troponin that indicates a heart attack is the level above the reference range. For example if the normal reference range is listed as 0.00 – 0.40. Then 0.41 is technically positive although very weakly so, and 10 is very positive.
What causes high troponin?
Many diseases, such as sepsis, hypovolemia, atrial fibrillation, congestive heart failure, pulmonary embolism, myocarditis, myocardial contusion, and renal failure, can be associated with an increase in troponin level. These elevations may arise from various causes other than thrombotic coronary artery occlusion.
What is a high troponin number?
TnI levels are typically considered elevated if they’re above 40 ng/L in a high-sensitivity test. TnT levels may be considered high if they’re above 14 ng/L for women and 22 ng/L for men in a high-sensitivity test.
What is high troponin level?
Very high levels of troponin are a sign that a heart attack has occurred. Most patients who have had a heart attack have increased troponin levels within 6 hours. After 12 hours, almost everyone who has had a heart attack will have raised levels. Troponin levels may remain high for 1 to 2 weeks after a heart attack.
What is normal range for troponin T?
Troponin test result ranges They are: Troponin I: 0 – 0.04 ng/mL. Troponin T: 0 – 0.01 ng/mL.
What is the difference between architect Stat hstnl and cTnI?
The ARCHITECT STAT High Sensitive Troponin-I (hsTnl) test is run in a lab setting. The cardiac troponin-I (cTnI) test is run at a person’s side, with Abbott’s i-STAT, which is a handheld, portable device used to perform a broad range of blood tests.
Is the Abbott architect Stat HS-TNI assay high sensitive TN test?
The new ARCHITECT STAT hs-TnI assay with improved analytical features meets the criteria of high sensitive Tn test and will be a valuable diagnostic tool. European multicenter analytical evaluation of the Abbott ARCHITECT STAT high sensitive troponin I immunoassay
What is the correlation coefficient of the architect stattroponin-I assay?
The ARCHITECT STATTroponin-I assay is designed to have a correlation coefficient (r) of ≥ 0.90. A study was performed where lithium heparin plasma specimens were tested in replicates of one using the ARCHITECT Troponin-I assay with two reagent lots on two instruments and compared to a commercially available diagnostic kit (Comparison Assay).
How do I install the architect stattroponin-I assay file?
• The ARCHITECT STATTroponin-I assay file must be installed on the ARCHITECT iSystem with STATprotocol capability from the ARCHITECT iAssay CD-ROM Addition B prior to performing the assay.
