  • cutoff
  • This cutoff for the "normal" level of troponin T was determined by looking at several studies of patients who were "apparently healthy" (no heart complaints) and had this level of troponin T in the bloodstream as a baseline. (medicinenet.com)
  • undetectable
  • In healthy people, troponin levels are low enough to be undetectable. (healthline.com)
  • In the first study -- a 3,546-person cohort study in Dallas led by de Lemos -- the adjusted hazard ratio for all-cause mortality was 2.8 (95% CI 1.4 to 5.2) for individuals with troponin T levels of 14 pg/mL and 1.7 for those with levels in the 4.4 to 6.7 pg/mL range, compared with participants with undetectable troponin T.

  • Absolute, unadjusted rates of heart failure and cardiovascular deaths ranged from 1.6 and 1.1 per 100 person-years, respectively, for participants with undetectable troponin T to 6.4 and 4.8 per 100 person-years among those in the highest quartile of the biomarker. (medpagetoday.com)
  • STAT
  • Roche Diagnostics Operations sent an "Urgent Medical Device Removal" letter to all of its customers known to have received the affected lots of Elecsys Troponin I or Elecsys Troponin I STAT. The letter described the product, the problem, and the actions to be taken. (newsinferno.com)
  • help diagnose
  • Since the first use of troponin testing, several generations of more refined and more reliable tests have been developed and used to help diagnose heart attack more rapidly and accurately. (medicinenet.com)
  • results
  • With the change in reporting units to ng/L, Troponin T results will be increased numerically by a factor of 1000 and the results will be reported in whole numbers. (sgh.com.sg)
  • With certain types of plasma samples, doctors may receive a falsely low result that can be up to a maximum of 50% lower than the actual concentration of Troponin I. These incorrect results may cause serious adverse health consequences, which include death. (newsinferno.com)
  • tissue
  • Immunohistochemical analysis of paraffin embedded Human colon carcinoma tissue, labeling Troponin T1 using ab155028 at 1/500 dilution. (abcam.com)
  • Please note: Troponin-I is very susceptible to proteolytic breakdown within cardiac tissue and it is difficult to isolate undegraded native human cardiac troponin-I. This product is greater than 70% intact and hence proteolytic fragments can be observed. (abcam.com)
  • detection
  • Until recently, the lower detection limit for troponin T -- released by stressed cardiac myocytes -- was 10 pg/mL, with relatively poor quantitative accuracy near this extreme. (medpagetoday.com)
  • reversible
  • Injury is usually considered irreversible (cell death), but definitive proof that cell death is always the cause when troponin is released, without possible contributions from reversible other mechanisms, is not available. (uptodate.com)
  • Reversible left ventricular dysfunction associated with raised troponin I after subarachnoid haemorrhage does not preclude successful heart transplantation. (springer.com)
