That’s why we continue to expand the breadth of our testing through leading diagnostics in a wide range of specialties, including our exclusive LRP4 antibody testing for myasthenia gravis (MG).
While MG most commonly involves either acetylcholine receptors (AChR) or muscle-specific kinase receptors (MuSK) that ultimately inhibit muscle contraction, some patients with the disorder will test negative for these antibodies.
For these cases, Quest provides another solution: LRP4 antibody testing. LRP4 antibodies are believed to be the third-leading cause of MG and were found in 13% of patients testing negative for other MG antibodies.1 With LRP4 antibody testing, we help you get the diagnosis you need to focus on treatment and patient care.
