The IHA test with monkey erythrocytes sensitized with measles virus hemagglutinin (HA) and fixed with glutaraldehyde was reported to be specific and sensitive for anti-measles antibodies (Ghyka et.
The IHA test was similar in principle to the hemagglutination inhibition (HI) test, as both tests exclusively determined the level of antibody directed to the HA spike of MV.
The antibody profile of all vaccinated and challenged animal were assessed through IHA test.
Post vaccinated and post challenged antibody response was detected through IHA test.
In the present study, the geometric mean titer (GMT) against IBD measured through IHA test
Eosinophilia and IHA test
were positive in 3 of these 4 suspected cases.
is an easily-available test, although its seroposi-tivity is about 50% in cases having lung cysts.
The serum from each of the blood sample was separated and stored in properly labeled vials at -40 0C for antibody titration through VN and IHA test
as described by Lewis et al, (1991) and Das et al.
However, we cannot exclude amebic liver abscess in these 2 patients because IHA test
results can be negative in HIV-infected patients (2).
has increasingly been used to demonstrate antibodies (Armstrong, et al.
The antibody titer of hyperimmune serum was calculated by using an IHA test
After 2 weeks, IHA tests
for Fasciola hepatica and Echinococcus granulosus were repeated, which were again positive at 1/5120 (normal: <1/160) and 1/320 (normal: 1/160), respectively.
