TROP T Sensitive rapid assay Myocardial assessment
Saves valuable time! The TROP T Sensitive rapid assay is easy to use, and the result is easy to read. The one-step test requires anticoagulated venous blood. It gives a reliable “yes/no” result within a 15 minute reaction time.7 Herkner H., Hirschl M.M., Laggner A.N., et.al (1997)
TROP T Sensitive rapid assay Reveals damage that other markers miss When myocardial damage is suspected, every minute counts. The TROP T Sensitive rapid assay allows rapid determination of the cardiac marker Troponin T from a single whole blood sample. A qualitative result is available within minutes – saving you precious time in emergency situations.
Troponin T is a highly specific and sensitive marker of myocardial damage. Numerous studies have confirmed this. 1–5 Determination of troponin T in the patients’ blood does not only allow detection of acute myocardial infarction but also recognition of minor myocardial damage (MMD). MMD is often missed using traditional diagnostic methods.5, 6
A positive troponin T test in a patient without characteristic ECG changes indicates increased medium- to long-term risk of a serious coronary event. This makes Troponin T an excellent prognostic indic ator of increased risk for further cardiac problems.3, 6, 8–12 > 0.1 ng/mL) Patients with an elevated troponin T value (− therefore require further testing, even if the ECG is unremarkable and symptoms are not clear-cut. Research has shown that the same seems to be true for patients with chronic renal insufficiency.16–18
Allows diagnosis even after several days Many patients only seek medical attention hours or even days after the onset of chest pain, especially on weekends. With the TROP T Sensitive rapid assay
you can make a diagnosis even after several days (up to 10 –14 days) after myocardial damage occurs.
Evaluation of test results from patients with chest pain and suspected myocardial infarction*: Emergency hospital admission with physician in attendance
Typical symptoms or ECG clearly positive
Atypical symptoms, ECG inconclusive
when TnT positive
Emergency hospital admission with physician in attendance
Atypical symptoms, ECG inconclusive
when TnT negative
Repeat ECG and TnT after 6 hours. If ECG normal, TnT negative and symptoms atypical: further outpatient investigation

Troponin T as criterion for making a therapy decision > 0.1 ng/mL) can be used Elevated troponin T levels (− to select therapy for unstable angina. In patients with refractory unstable angina, it has been shown that treatment with a platelet aggregation inhibitor (GPIIb/ IIIa inhibitor)13, 14 or low molecular weight heparin11 is most effective in patients with increased troponin T values.
Further investigations show that using troponin T tests for determining treatment with a GPIIb/IIIa inhibitor is costeffective.15
TROP T Sensitive How to perform the test Remove the strip from the package and place it on a flat surface. Use either EDTA or heparinized venous blood!
Obtain the blood sample
Draw up 150 µL (± 15 µL) blood into the dispensing aid
Apply the sample to the test strip and read result after 15 minutes
or
a) Single line (control line) = negative test result (troponin T concentration < 0.1 ng/mL)
b) 2 lines (control and signal line) = positive test result (troponin T > 0.1 ng/mL). concentration − c) no control line = invalid test (repeat test)
