However, serologic testing is not useful for patients with previous infections.
2.
Most commonly serologic testing and PCR amplification are used.
3.
Serologic testing looks for the presence of antibodies against the adult schistosome in the blood.
4.
PCR may be at least as serologic testing.
5.
Serologic testing has also been used to diagnose the presence of botfly larvae in human ophthalmomyiasis.
6.
Serologic testing is not recommended for pet rodents, as it has been unreliable in detecting antibodies in animals with active infections.
7.
Retrospective serologic testing subsequently demonstrated that up to 230 soldiers had been infected with the novel virus, which was an H1N1 strain.
8.
Since detectable antibody responses require about a week after infection to develop, serologic testing may be falsely negative early in the disease course.
9.
Diagnosis of West Nile virus infections is generally accomplished by serologic testing of blood serum or cerebrospinal fluid ( CSF ), which is obtained via a lumbar puncture.
10.
It is common in serologic testing for cross-reactions to occur among flaviviruses such as dengue virus ( DENV ) and tick-borne encephalitis virus; this necessitates caution when evaluating serologic results of flaviviral infections.
