A response to "Serum-ethanol determination: comparison of lactate and lactate dehydrogenase interference in three enzymatic assays".
Gas chromatography is considered to be the reference method for ethyl alcohol determination. However, enzymatic ethanol assays have been developed for use in the clinical laboratory by several commercial vendors. Essentially, these assays utilize the oxidation of ethyl alcohol to acetaldehyde with concurrent reduction of nicotinamide adenine dinucleotide (NAD) to NADH while monitoring the incre...
متن کاملTransient appearance of lactate dehydrogenase (LDH)-linked immunoglobulin and thyroid dysfunction at the postpartum period.
Here, we report a 28-year-old woman who transiently showed lactate dehydrogenase (LDH)-linked immunoglobulin during postpartum thyroiditis. She demonstrated high levels of serum LDH (794 IU/l) and thyroid hormones 7 months after delivery. Electrophoretic isoenzyme analysis of LDH showed an abnormal broadband caused by LDH-linked immunoglobulin (IgG-kappa). Transient thyrotoxicosis due to postpa...
متن کاملSensitivity and specificity of viral immunoglobulin M determination by indirect enzyme-linked immunosorbent assay.
Four sources of error associated with virus-specific immunoglobulin M (IgM) determination by indirect enzyme-linked immunosorbent assay were recognized and analyzed. First, competitive inhibition due to specific IgG was demonstrated by experiments involving addition and subtraction of rubella-specific IgG. Second, the interference due to rheumatoid factors (RFs) of the IgM class (IgM-RFs) was s...
متن کاملHemolytic Events in Rh Positive Neonates Born to Rh Negative Mothers
Background One of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including Rh incompatibility. The aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in Rh positive neonates born to Rh negative mothers. Methods In this retrospective study from March 1998 to February 2003, 60 icteric Rh positive newborns that were born to Rh negative m...
متن کاملPositive interference in Radioimmunoassay determination of serum total T3
Introduction: Determination of thyrotropin, total and free thyroxine and triiodothyronine are widely used as diagnostic methods for thyroid function evaluation. There have been numerous reports of interferences in thyroid hormone immunoassays. Herein, a prominent positive interference is reported for a radioimmunoassay kit of total triiodothyronine. Materials and Methods: In this study, a total...
