background the occult hepatitis b infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the sera or in the liver biopsy and the absence of hepatitis b surface antigen (hbsag) by serological test. objectives the current study aimed to evaluate the occult hbv infection by polymerase chain reaction (pcr) and determine hbv genotyping among the patients with abnormal alanine t...

BACKGROUND The safe transfusion of patients with warm autoimmune hemolytic anemia requires an efficient and time-saving assay to detect alloantibodies underlying autoantibodies. Methods used include RBCs treated with ZZAP reagent, proteolytic enzyme, or untreated RBCs in the presence of PEG. We propose a method using LISS, which presents some advantages over previous methods. STUDY DESIGN AND...

background: the most reliable indicator of vitamin d status is circulating concentration of 25‑hydroxycalciferol (25(oh) d) routinely determined by enzyme‑immunoassays (eia) methods. this study was performed to compare commonly used competitive protein‑binding assays (cpba)‑based eia with the gold standard, high‑pressure liquid chromatography (hplc). methods: concentrations of 25(oh) d in sera ...

An automated immunonephelometric assay was developed to measure vitamin D-binding protein (DBP) in serum. The assay is described for the Behring Nephelometer System, which uses rabbit anti-DBP antiserum and purified human DBP. The detection limit is 0.05 g/L (0.86 mumol/L), and the working range is less than or equal to 1.60 g/L (27.59 mumol/L). Intra- and interassay CVs of 2.0% and 2.8-3.8% co...

Autoantibodies to components of the nucleolus are a unique serological feature of patients with scleroderma. There are autoantibodies of several specificities; one type produces a speckled pattern of nucleolar staining in immunofluorescence. In actinomycin D and 5,6-dichloro-beta-D-ribofuranosylbenzimidazole-treated Vero cells, staining was restricted to the fibrillar and not the granular regio...

Human heterophilic hemagglutinin to rabbit erythrocytes was quantitatively determined by the hemagglutination test and enzyme linked immunosorbent assay (ELISA) using rabbit erythrocyte pentaglycosyl ceramide (CPH), Gal (a 1-3) Gal (fl 1-4) GlcNAc (fl 1-3) Gal (fl 1-4) Glc-Cer as the antigen. The antibody levels in sera from 74 Hanganutziu-Deicher (H-D) antibody-positive patients were significa...
