Randox Launches High Sensitivity Troponin T Control

Troponin T is used in the assessment of Myocardial Infarction (MI), where even small elevations in its level indicate damage to the heart. The European Society of Cardiology (ESC) and the American College of Cardiology (ACC) recommend use of a highly sensitive Troponin assay with excellent precision (less than 10% CV) at the 99th percentile of the reference range.

Until now, suitable control material for high sensitivity Troponin T, with target values sufficiently close to the 99th percentile of the reference range (14ng/L), were unavailable. However, the recent launch of the Randox Acusera High Sensitivity Troponin T Control has changed this and now laboratories are able to more accurately monitor and assess the performance of their high sensitivity Troponin T assays.

The ultra low Troponin T levels found in the Randox control are significantly lower than those found in other manufacturers QC material. Target values for the Randox control are generally around 16.5ng/l (range 12.4 – 20.6ng/l) and are closest to the 14ng/ml cut off. The Acusera control has a shelf life of up to 4 years so the same lot of control material can be used for longer, reducing the problems associated with lot crossovers. A reconstituted stability of 5 days at +2- +8oC or 4 weeks at -20oC minimises unnecessary waste and provided significant cost savings.

Randox also manufacture a liquid cardiac control with assayed values for an impressive 10 cardiac markers including BNP, CK-MB, D-dimer, Digoxin, Homocysteine, hsCRP, Myoglobin, NT-ProBNP, Troponin I and Troponin T. As the name suggests the control is liquid ready to use for added convenience and ease of us. Three levels are available spanning the complete clinical range with cut off levels for both Troponin I and T in line with international recommendations.
