Antihepca™- HRRS

Find out fast : simply repeat the APTT test with Antihepca™-HRRS as the recalcifying solution. A prolonged APTT due to heparin contamination will correct.

Find out for less : cost effective and practical sizing of kits, 200 tests per 10ml, 1000 tests per kit. Based on use in hospital laboratory settings. Economical pricing

Find out easily : Antihepca™-HRRS is a ready-to-use liquid reagent that integrates smoothly into your workflow.

Find out reliably : Long stability, shelf life of 5 years at 2-8°C.

Compatible with all Automated analyzers : simply replace CaCl₂ with Antihepca™-HRRS to neutralize UFH up to 1.0U/ml.

Heparins are widely used in hospitals as anticoagulants. Unfractionated heparin is usually monitored using APTT and thrombin time tests. Often plasma samples are not identified as containing heparin and it may be present as an unexpected contaminant. Thus the reason for prolonged APTT or KCT tests may not be apparent and laboratory diagnosis may not be simple. Laboratories may find it useful to have a simple method for confirming the presence of heparin before going on to other investigations as may be required.

​Several methods are available to remove heparin including heparinase enzyme (expensive), adsorbing agents such as ECTEOLA cellulose (not so simple) and specially treated filters. Some polymers have also been widely used to neutralise heparin, however, in excess, they can interfere with contact activators used in most APTT reagents. Thus it is more reliable to add the heparin neutralising agent in the calcium chloride solution after the contact activation stage in APTTs or KCTs. Antihepca™ HRRS is a simple and unique product which we believe will play a regular role in routine coagulation testing.
