A Hemagglutination-Inhibition Test for Mycoplasma meleagridis Antibodies
Avian Diseases, 1969A hemagglutination-inhibition test for demonstrating antibodies to Mycoplasma meleagridis is reported. Antigen used in the test was prepared from a hemagglutinating strain of M. meleagridis isolated from a turkey embryo. The antigen, suspended in phenolized saline, could be stored at 50C for weeks and still be effective. Examination of serums from both

Hemagglutination-Inhibition Test for Methamphetamine Excreted in Human Urine
Journal of Forensic Sciences, 1979Abstract Recently radioimmunoassay (RIA) methods have been developed for the determination of nanogram levels of methamphetamine in urine [1–3]. These methods are suitable for rapid screening but require expensive instrumentation.

Simple hemagglutination inhibition test for the diagnosis of toxoplasmosis
Journal of Clinical Microbiology, 1985A simple hemagglutination inhibition (HI) test for the serological diagnosis of toxoplasmosis has been developed and evaluated. A total of 84 human and 120 mouse serum samples were tested by the newly developed HI test and compared with an immunoglobulin G-indirect fluorescent antibody test. Statistical analysis of serum titers obtained by using the HI

Preparation of Newcastle Disease Virus Hemagglutination-Inhibition Test Antigen
Avian Diseases, 1975A method of preparing antigen for Newcastle hemagglutination-inhibition (HI) tests is described; polyethylene glycol precipitation is used for the virus concentration. The virus was inactivated with either formalin or beta-propiolactone. Glycerin was used to stabilize the hemagglutinin activity of the antigen.

Use of Turkey Erythrocytes for Vaccinia Virus Hemagglutination and Hemagglutination-Inhibition Tests
American Journal of Clinical Pathology, 1974Turkey erythrocytes are uniformly susceptible to agglutination by vaccinia virus hemagglutinin prepared from the chorioallantoic membrane of the chick embryo and from primary rabbit kidney tissue cell cultures. Forty-seven lots of erythrocytes were tested and all were agglutinated by vaccinia virus.

SUMMARY A satisfactory hemagglutinating (HA) antigen was produced from isolate WVU 1853 of M. synoviae grown in a mycoplasma broth formulated by Frey. The HA antigen, employed in the HI test, showed good specificity in differentiating M. synoviae from M. gallisepticum infection.

Rubella Hemagglutination-Inhibition Test Using Erythrocytes from Albino Pigeons
American Journal of Clinical Pathology, 1971The use of pigeon erythrocytes for the quantitation of rubella hemagglutinin and for titration of antibody is described. Results are compared with those obtained with erythrocytes from freshly hatched chicks. Both hemagglutinin titers and hemagglutination-inhibition antibody titers using pigeon cells were similar to those observed with day-old chick ...
