BACKGROUND The chemiluminescent microparticle immunoassay (CMIA) is widely used for the quantitative determination of B-type natriuretic peptide (BNP) in human ethylenediaminetetraacetic acid plasma. Rheumatoid factor (RF) is usually thought to result in a positive interference in immunoassays, but it is not clear whether its presence in plasma can lead to(More)
BACKGROUND Rheumatoid factor (RF) can interfere both positively and negatively in immunoassays. It remains unclear whether the negative interference is an exceptional phenomenon or a denominator of immunoassays and which RF subgroup plays a key role in its causation. METHODS Serum models comprising hepatitis B envelope antigen (HBeAg) and RF were made by(More)
The shipment and storage conditions of clinical samples pose a major challenge to the detection accuracy of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Ureaplasma urealyticum (UU) when using quantitative real-time polymerase chain reaction (qRT-PCR). The aim of the present study was to explore the influence of storage time at 4°C on the DNA(More)
