Analytical performance of Bayer Immuno 1 estradiol and progesterone assays.
We evaluated the analytical performance of new estradiol and progesterone assays performed on the Bayer Immuno 1 system. Within-run and between-day CVs for estradiol at concentrations of 116.8-6645.8 pmol/L were < or = 6.4% and for 5.54-103.95 nmol/L progesterone were < or = 7.7%, thus meeting published analytical goals. The detection limits (2 SDs from mean of zero calibrator) were 27.1 pmol/L...
متن کاملSerum bioavailable testosterone: assayed or calculated?
BACKGROUND Bioavailable testosterone (BT), circulating testosterone not bound to sex hormone-binding globulin (SHBG), is thought to easily penetrate cells. We compared BT measurements obtained by assays with those obtained by calculation with different testosterone association constants. METHODS We obtained sera from 2 groups of hypogonadal men [group 1 (G1), 1421 samples; group 2 (G2), 170 s...

15 صفحه اولThe role of albumin in the calculation of free and bioavailable testosterone in women with hyperandrogenemia.
BACKGROUND The aim of this study was to assess the role of albumin in the calculation of free testosterone (cFT) and bioavailable testosterone (cBT). PATIENTS AND METHODS Ninety-two healthy women, who presented at our fertility center for evaluation of possible hyperandrogenemia, were included in the study. Total blood testosterone (TT), free testosterone (FT) and sex hormone-binding globulin...
متن کاملImplementation of Automated Calculation of Free and Bioavailable Testosterone in Epic Beaker Laboratory Information System
BACKGROUND Automated calculations by laboratory information system (LIS) are efficient and accurate ways of providing calculated laboratory test results. Due to the lack of established advanced mathematical functions and equation logic in LIS software, calculations beyond simple arithmetic functions require a tedious workaround. Free and bioavailable testosterone (BT) calculations require a qua...
