Patients tested after 5 days of the onset of symptoms might have tested negative via RT-PCR, but could have tested positive for Zika through serology and plaque reduction neutralization test
10) Neutralizing antibodies, detected by plaque reduction neutralization tests
(PRNTs), become detectable concurrently with IgM but persist for years.
Comparison of measles antihemolysin test, enzyme-linked immunosorbent assay, and hemagglutination inhibition test with neutralization test
for determination of immune status.
Comparison of an enzyme-linked immunosorbent assay with serum neutralization test
for serodiagnosis of porcine epidemic diarrhea virus infection [J].
perfringens strains were then typed for their toxigenicity and typing by the mice neutralization test
and dermonecrotic test in guinea pigs (Murray et al.
The article by Chen and Kaplan in this issue of Clinical Chemistry (2) found a high frequency of weakly positive HBsAg results with 2 lots of reagent sets from one manufacturer; most of these weakly positive results were falsely positive (negative neutralization test
Blood samples from 480 bovine were collected for detection of antibodies against BHV-1 by viral neutralization test
2% of 141 nestling red-tailed hawks (Buteojamaicensis), and 12% of 73 nestling great horned owls (Bubo virginianus) tested positive for WNV antibodies by the constant virus-serum dilution neutralization test
The test revealed presence of immunoglobulin M in serum by antibody-capture enzyme-linked immunosorbent assay and was confirmed by a positive plaque reduction and neutralization test
for WNV and a negative plaque reduction and neutralization test
for other flaviviruses.
We retested samples exhibiting [greater than or equal to]25 Vienna units/mL by using virus neutralization test
(VNT) as described previously (6).
Bovine Viral Diarrhea Virus (BVDV) antigens and antibodies in samples were investigated with Antigen Capture ELISA (ACE) and Serum Neutralization Test
