What are the biocompatibility tests?

An integral part of biological risk assessment, biocompatibility testing assesses the compatibility of medical devices with a biological system. It studies the interaction between the device and the various types of living tissues and cells that are exposed to the device when it comes into contact with patients.

1970s. 1971. The founding name of ‘Science Associates’ was changed to ‘North American Science Associates, LLC’ (NAMSA); the company moved to its current corporate headquarters in Northwood, Ohio. 1976.

Does namsa test on animals?

By far most common method that NAMSA uses, the guinea pig maximization test, is also the most widely recognized. Typically done with 15 guinea pigs per extract (10 with the test extract, five with the control).

What is in vivo biocompatibility?

Abstract. An in vivo method is described for screening polymeric materials for biocompatibility. The test is based on grading acute and subacute tissue reactions at 7 and 28 days, respectively, following implantation in rats.

How is biocompatibility measured?

Cell culture assays are used to assess the biocompatibility of a material or extract through the use of isolated cells in vitro. These techniques are useful in evaluating the toxicity or irritancy potential of materials and chemicals. They provide an excellent way to screen materials prior to in vivo tests.
