[IgM in the diagnosis of syphilis: results on the use of the IgM solid-phase hemadsorption test].

IgM-SPHA test was improved for IgM treponema-specific determination. The test can find routinary application because it does not require for its execution special equipments, and is very easy. With this test 160 sera of luetic subjects were examined 103 were treated and 57 were affected by lues at different stages and untreated. The test is rather sensitive in the secondary and latent lues and in the reinfections, while the results are paradoxically less satisfactory in the primary syphilis. The test can be a precious diagnostic tool since, beside allowing to decide the recovery from the disease from an immunological point, finds further applications in the connatal and neurological lues.
