How do you test for metal sensitivity?

The lymphocyte transformation test (LTT) is a blood test that can detect if the patient has a metal hypersensitivity (immunological memory to metal-haptens). The lymphocyte transformation test has been available for over 25 years and was first used as a test to detect drug hypersensitivity reactions.

Which of the tests is recommended in suspicion of metal allergy?

Listen to patient’s concerns about metal allergy if the concern arises. Patch testing is probably the best pre- and post-implant screening test. Post-implantation testing is controversial and even positive LTT or patch test does not definitively diagnose morbidity from a metal allergy.

What is lymphocyte proliferation assay?

The lymphocyte proliferation assay (LPA) is a technique to determine T-lymphocyte functions in vitro. To determine whether whole blood composing between heparinized blood and ACD blood could be substituted for standard LPA using PBMC.

Can you be allergic to titanium hip replacement?

Total hip and knee replacement surgery using metal alloy devices is common. Type IV allergic reactions to these implants occur, though infrequently.
