PCT No. PCT/US94/12228 Sec. 371 Date May 6, 1996 Sec. 102(e) Date May 6, 1996 PCT Filed Oct. 27, 1994 PCT Pub. No. WO95/12685 PCT Pub. Date May 11, 1995There is described an assay for the diagnosis of a mental disorder in an individual. A blood sample, a platelet-containing fraction thereof, or a fraction containing platelet-associated antibodies (PAA) shed from the platelets is withdrawn from the individual to be diagnosed. The withdrawn sample is contacted with an anti-human immunoglobulin antibody lacking the Fc domain (Fc-less anti-hIg antibody) and the degree of binding thereof to the PAA is determined. A degree of binding above that found in normal individuals indicates that diagnosed individual has a high likelihood of having a mental disorder.
