Hemagglutination is the use of this property to test for blood types; anti-A Ab anti-B Ab, and a mixture of anti-A and anti-B Ab are added to aliquots of a blood sample, and the clumping (agglutination) indicates the blood type.
The indirect antiglobulin test is also called an antibody screen.
In this test, a few drops of patient serum is placed in a small test tube with a drop of reagent red blood cells and checked to see if there is an antigen-antibody reaction.

Isolation rates have been as high as 86% in patients not receiving antibiotics at the time of culture, with as little as 5 ml of blood incubated at a high (1:4) blood-to-broth ratio in an unsupplemented broth bottle.
Because seropositivity reflects evidence of infection rather than actual disease, complement fixation, hemagglutination, and fluorescent antibody tests are primarily used for confirmation of the clinical diagnosis.
The indirect hemagglutination (IHA) test is considered to be more specific than the complement fixation tests.

In some patients titers of IgG increased markedly between 2 and 4 months after onset of illness and remained readily demonstrable by indirect immunofluorescence 3 years after infection.
Techniques for demonstrating antibody were (in order of decreasing sensitivity) enzyme-linked immunosorbent assay, reversed passive hemagglutination-inhibition, indirect immunofluorescence, fluorescent-focus reduction, complement-fixation, and immunodiffusion.

In both groups older animals had a significantly increased frequency of such antibodies, but the titer was age-independent.
The specificity of natural antibodies for MHC-encoded antigens was investigated in indirect immunofluorescence tests including absorption experiments with RBC and white blood cells (WBC).

In the remaining cases, a straightforward diagnosis of hydatid disease could not be made either because surgery was not done or results of surgery were not available.
The indirect hemagglutination (IHA) test has been preferred since its introduction by Garabedian and associates by virtue of its simplicity and sensitivity and is a valuable method for the serodiagnosis of HD.

 Hardy Diagnostics: Glossary
Indirect fluorescent antibody; test that detects antibody by allowing an antibody to react with its substrate and adding a second fluorescein dye-labelled antibody that will bind to the first.
In addition to improved specificity with the removal of operator subjectivity, the quantifiability of results through computer data analysis of color, intensity and concentration has only begun to be realized.
However, in the indirect IP instead of fluorescent dye-antibody conjugates, enzyme-antibody conjugated (principally peroxidase enzymes) are reacted with their corresponding substrates to produce a product which can be seen with a light microscope, eliminating the requirement for costly fluorescent microscopic equipment.

The direct and indirect fluorescent antibody tests are the most effective of the various serological methods for identifying most mycoplasmas (27).
Acute cases caused by Mccp rarely show positive titres to the organism before death (21, 25, 36), perhaps because antibodies are 'eclipsed' by circulating mycoplasma antigens (25).
Seroconversion to Mccp in experimentally infected animals is observed by the complement fixation (CF) test and indirect haemagglutination (IHA) test to start 7-9 days after the appearance of clinical signs, to peak between days 22 and 30, and to decline rapidly thereafter (25).

 Serodiagnosis of Chronic Chagas Infection by Using EIE-Recombinant-Chagas-Biomanguinhos Kit
Evaluation was performed with 368 serum samples collected from individuals living in an endemic area for Chagas disease: 131 patients in the chronic phase with confirmed clinical, epidemiological, and serological diagnosis (indirect immunofluorescence, indirect hemagglutination or enzyme-linked immunosorbent assay) and 237 nonchagasic seronegative individuals were considered negative control.
Diagnosis of chronic Chagas disease is based on the detection of parasite by indirect parasitological methods (xenodiagnosis and hemoculture) or more usually on the detection of IgG antibodies against T.
The methods based on detection of the parasite, although highly specific, are of limited sensitivity, because parasites are detected in only 20-50% of individuals known to be infected, resulting in many false negative results (Gomes 1997).

In the study of antibody decay, serum samples from the 27 patients were divided into two groups: 14 (group A) were assayed by 8 types of immunofluorescence (IF) tests and the remaining 13 (group B) by the indirect hemagglutination (IHA) test because of the low volume of serum available.
The overall serologic data showed that all 14 patients in group A presented antibody decay for at least one of the 8 tests, 4 (29%) of them presented antibody decay in one or two tests, 7 (50%) in 4 to 6 tests, and 3 (21%) in 7 or 8 tests.
