2. Manufacturer


Takeda production site in Linz, Austria, holder of  EN ISO 13485:2016+AC:2009 certifications for Medical Devices.



3. Categorisation of therapeutical area


Collagen Reagens HORM® can be categorized as a diagnostic product widely used in haematological laboratories and/or blood preservation institutions. It is a suspension of native collagen fibrils acting as inductor of platelet aggregation.



Blood coagulation is a highly complex and sophisticated system to maintain vascular integrity. In case of injuries, platelet adhesion to vessel wall collagen plays a fundamental role in initiating complex interactions that in the end lead to formation of platelet aggregates. These can be considered a “peg” that consequently tightens the injured vessel.


  • Disorders in the hemostasis system may lead to a series of severe conditions, such as myocardial infarction, strokes and peripheral arterial diseases.


  • Platelet and coagulation associated diseases comprise among others
    • Abnormal platelet counts (thrombocytopenia or thrombocytosis)
    • Different syndromes (Bernard Soulier syndrome, Glanzmann’s thrombasthenia, von Willebrand disease)
    • Drug induced malfunctions
    • Age induced malfunctions


4. Description of product


Collagen Reagens HORM® is a suspension of native equine tendon collagen (type I). It is classified an in-vitro diagnostic medical device used for the determination of platelet aggregation capacity. Collagen fibrils act as an inductor of platelet aggregation - the product  may therefore be used to


  • assess platelet function
  • detect von Willebrand disease/differentiate subtypes
  • predict possible risks with cardial interventions
  • monitor antithrombotic therapies (e.g. ASA [Aspirinâ])


5. Advantages and characteristics:

  • Can be used with different analytic equipments (types of aggregometers)
  • Different analytical methods (turbidimetric, electric impedance method)
  • Individual dilutions possible – no pre-fabricated cartridges
  • Equine origin
  • Native fibrillar structure
  • Suspension manufactured by a unique and very smooth process
  • Delivered directly


6. Packaging sizes


KRH is available as

  • set presentation composed of 1x4 ml reagent plus 4x10 ml diluting solution
  • diluting solution 5x10ml

9. Frequently Asked Questions


Q: How is the adjustment of a pH-value between 2,7-2,9 done for the isotonic glucose solution (SKF solution)?

A: The adjustment is done with lactic acid.


Q: Do you have any antibody that reacts well with Collagen Reagens Horm?

A: No


Q: What are the dimensions of the standard box?

A: Collagen Reagens Horm, Takeda ref: 1130630  (1 vial collagen + 4 ampoules SKF solution) packed in polystyrol: 12 x 13,5 x 5 cm. Weight of the standard box: 109 grams


Q: What is the origin of Collagen Reagens Horm?

A: Country of origin is Austria.


Q: What type of collagen is Collagen Reagens Horm?

A: Collagen Reagens Horm is produced from equine tendons. The predominant collagen in tendons is Type I. We do not test our Collagen Reagens Horm batches specifically for their compositions of collagen types. As it is known from literature Collagen Reagens Horm contains a mixture of approximately 95% Collagen Type I and 5% Collagen Type III. (see literature reference Nr. 10: Favaloro E.J; Thromb. Haemost. 2000; 83: 127-135)


Q: What is the recommended shipping temperature?

A: Shipping temperature = storage temperature: + 2 to + 8 °C.


Q: Details of any temperature cycle assessments, i.e. permitted number of excursions from the specified shipping / storage temperature?

A: Maximum allowable cumulative time of temperature excursion +8 to + 25 °C = 1 day. No excursions below + 2°C allowed.
