There are various types of biocompatibility tests depending on the type of therapy the material is involved in delivering. One of the most important is cytotoxicity test that goes hand-in-hand with hemocompatibility. Cytotoxicity tests check for sustenance and maintaining the health of all the tissues in the body post administration of the drug. It differs for different applications: for example as biomaterials in contact with the uterine tissue need to pass the uterine tissue biocompatibility tests and biomaterials in contact with the neural tissue and so on. However, for orthopedic implants, apart from biocompatibility and hemocompatibility tests, one has to test the structural strength of the implant as each implant is custom made according to the demographics of the patient. It is important to check the strength and stability of the orthopedic implant to ensure its long-term usefulness and effectiveness.
