Objective: To analyze the laboratory results of a Sjögren’s syndrome combining autoimmune hepatitis (SS-AIH) with double negative of SSA and SSB (SSASSB). Methods: 10 ml venous blood was collected from the patients, and the blood routine, biochemical and immunological indices were respectively detected. Results: The values of WBC, neutrophiles, ESR, ALT, AST, CRP, IgA and IgG were beyond the co...

Reference ranges and control limits are used in many settings – for example, to assess a person’s health or monitor the stability of manufacturing process. Such established based on baseline sample what is considered normal data, but it not possible always avoid few outliers being present even this sample. If, as common, range calculated using statistics, such mean standard deviation, which cou...

The quantification of neurotransmitters or their metabolites in cerebrospinal fluid (CSF) can provide valuable clues for the detection of (often treatable) genetic disorders or their biosynthesis or salvage pathways. These analyses are technically demanding since the concentrations to be assessed are in the nanomolar range. To date, only a few laboratories worldwide offer these analyses. Since ...

OBJECTIVE The purpose of this study was to establish longitudinal reference ranges for fetal ultrasound biometry measurements and growth parameters in twin pregnancies. METHOD A total of 200 uncomplicated twin pregnancies before 21 weeks of gestation were recruited for this prospective, longitudinal study. Women who abandoned follow-up, pregnancies with unknown outcomes or pregnancies with co...

It has been suggested that an increase in serum alanine transaminase (ALT) activity in blood donors may identify infection with non-A, non-B hepatitis. To facilitate identification of such donors, the reference range for ALT was measured on a Technicon SMAC 1 Analyser, using serum from 364 blood donors and 567 plasmapheresis donors. The distribution of ALT activities displayed a positive skewne...
