OBJECTIVE To compare the performance of the MONO-LEX system to that of the MONO-TEST in detecting infectious mononucleosis (IM) heterophil antibodies. METHODS Baptist Regional Laboratories, Memphis, Tennessee. METHODS Not applicable. PRODUCT COMPARISON: The MONO-LEX system, manufactured by Trinity Laboratories, Raleigh, North Carolina, distributed by Gull Laboratories, Salt Lake City, Utah, and the MONO-TEST kit, manufactured by Wampole Laboratories, Cranbury, New Jersey, are agglutination assays that show visible agglutination when reagents are mixed with serum or plasma containing IM heterophil antibodies. METHODS Accuracy in detecting heterophil antibodies in the study specimens, ease of interpreting test results, and cost-effectiveness. RESULTS Of the 139 specimens tested, 132 produced the same results using both products and seven produced discrepant results. The possibility that the MONO-TEST produced a "prozone effect" was eliminated. Titration of sera that tested positive for heterophil antibody by both methods revealed titers as high as 1:152 by the MONO-LEX compared with 1:128 by the MONO-TEST. A total of 31 specimens that tested positive for IgM antibodies to Epstein-Barr virus nuclear antigen by enzyme immunoassay were assayed using the two methods; MONO-LEX detected heterophil antibodies in eight sera while the MONO-TEST detected antibody in only four samples. CONCLUSIONS The MONO-LEX surpassed the MONO-TEST in sensitivity, cost-effectiveness, and ease of interpretation.

UI	MeSH Term	Description	Entries
D007244	Infectious Mononucleosis	A common, acute infection usually caused by the Epstein-Barr virus (HERPESVIRUS 4, HUMAN). There is an increase in mononuclear white blood cells and other atypical lymphocytes, generalized lymphadenopathy, splenomegaly, and occasionally hepatomegaly with hepatitis.

D007841	Latex Fixation Tests	Passive agglutination tests in which antigen is adsorbed onto latex particles which then clump in the presence of antibody specific for the adsorbed antigen.

D000910	Antibodies, Heterophile	Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies-specific antigens, the best known of which are Forssman, Hanganutziu-Deicher (H-D), and Paul-Bunnell (P-B). Incidence of antibodies to these antigens--i.e., the phenomenon of heterophile antibody response--is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification.

D012680	Sensitivity and Specificity	Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)	Specificity,Sensitivity,Specificity and Sensitivity
