Background: Beta-human chorionic gonadotropin (beta-hCG) is secreted in small amounts by all cells and since the hormone is largely excreted by the kidneys, its levels can be elevated in non-pregnantdialysis patients.
Case presentation: A 27-year-old...
Objective: In this study we aimed to calculate the median levels of free β-hCG and PAPP-A levels of pregnant women in our area and to search the relationship between the pregnancy complications and these medians.
Material and Methods: The serum free...
Aim: A number of recent reports have investigated the origin of false-positive hCG results. This case report demonstrates a slightly high true positive hCG in a young female patient with chronic kidney disease.
Materials and Methods: The patients serum...
Aim: The uncertainty of measurement is an important indicator for both the expediency of a method and the reliability of analytical results obtained in a laboratory. Accreditation processes such as ISO 15189 also expect laboratories to have a defined method for measurement...
Objective: Combine test (between the 11 th and 14th weeks of gestation) and triple test (between the 16 th and 18th weeks of gestation) are being used for trisomy 21 and trisomy 18 screening. We have investigated the precision of fetal nuchal translucency (NT), free β HCG...
Objective: The aim of this study is to determine the new median values of biochemical analytes used in double and triple prenatal screening tests and to compare these values with the median values of the package program used in screening tests.
Materials and...
Objective: First trimester screening tests are widely used for the diagnosis of chomosomal anomalies. In our study, we investigated the effect of maternal smoking on first trimester screening tests in pregnant women who applied to our laboratory.
Material and...
Aim: Sigmametric methodology is used as a quality management tool that predicts variables can be controlled and targets zero error.In this study, sigmametrics were calculated for some fertility function tests to pick the suitable quality control tools and approach for...
Aim: To determine the current median values for hormone parameters used in first trimester screening test for Kayseri province and to compare the median values with those in the software used for reporting of screening test and those detected for other regions found with...
Objective: The purpose of this study is to determine the median values of the double test screening parameters in Bursa region and to reevaluate the test results positive risky pregnancies according to previous computer programme.
Materials and Methods:...
Aim: The Intra-laboratory Turnaround Time (IR-TAT) serves as a significant measure of overall laboratory efficacy. This study sought to augment laboratory operational productivity and diminish IR-TAT by instating a Total Laboratory Automation (TLA) system, executing stat...
Background: First trimester prenatal screening gives the risk rates associated with aneuploidies. Measurement uncertainty is defined as a magnitude showing distribution of the measured values. The aim of this study is to investigate the effects of measurement uncertainty on...
Objective: The purpose of this study is to determine the median values of the triple test screening parameters in pregnancy in Bingöl region, and to compare the median values determined for the currently used programs and some other provinces.
Material and...
Objective: The purpose of our study was to determine the median values of the triple test screening parameters in pregnancy in our region.
Material and Methods: In this study we evaluated the serum alpha feto protein (AFP), unconjugated estriol (uE3)...
