The use of TORCH titers.
Of 603 patients undergoing serologic tests for Toxoplasma, syphilis, rubella, cytomegalovirus, and herpes simplex (TORCH tests) during a 4-year period, 381 (63%) were infants younger than 6 months and 110 (18%) were either the mothers of those infants or pregnant women. The remaining 112 (19%) were older infants and children, male adults, or nonpregnant female adults. Of 381 infants less than 6 months of age who were tested, 323 (85%) had only a single TORCH test. Of 35 (9%) infants who had follow-up titers, 16 (46%) had a specific titer requested whereas in 19 (54%) the entire TORCH battery was repeated. Follow-up titers were infrequently (25%) requested when initial titers were elevated. Infection with a TORCH agent was not confirmed serologically in any of the 603 patients. The pattern of TORCH test use has a poor diagnostic return.
