Detection of biological false positive syphilis serum reactions.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
A comparative evaluation of reagin tests (Wassermann, VDRL, RPR) and fluorescent treponema antibody absorption tests (FTA-ABS) performed on blood specimens from 5 271 persons (2 493 pregnant women, 1 130 apparently healthy prospective employees, 1 345 newborn babies and 303 leprosy patients) showed that 17,2% of the pregnant women, 11,95% of the ...

Optimization of TaqMan-based quantitative PCR diagnosis for Entamoeba histolytica using droplet digital PCR.

PLoS Neglected Tropical Diseases
BackgroundTaqMan-probed quantitative PCR (qPCR) is highly valued for diagnosing Entamoeba histolytica infections (amebiasis). However, unclear cycle threshold (Ct) values often yield low-titer positive results, complicating interpretation.

Comparative study of immunoassays, a microelectromechanical systems-based biosensor, and RT-QuIC for the diagnosis of chronic wasting disease in white-tailed deer

BMC Veterinary Research
Background Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy in cervids. The disease is caused by a pathogenic prion, namely PrPSc. Currently, diagnosis of CWD relies on IHC detection of PrPSc in the obex or retropharyngeal
