Optimization of a pre-MEKC separation SPE procedure for steroid molecules in human urine samples.
Many steroid hormones can be considered as potential biomarkers and their determination in body fluids can create opportunities for the rapid diagnosis of many diseases and disorders of the human body. Most existing methods for the determination of steroids are usually time- and labor-consuming and quite costly. Therefore, the aim of analytical laboratories is to develop a new, relatively low-c...
متن کاملSeparation of Fastidious Bacteria in Aging Women Urine Samples
Objectives: Urinary tract infections are today counted aging as one of the infectious and hospital related disease with high especially in aging women. As we know the infection would be identified in urine sample based on KASS scale while in spite of valuable usage of this method the culture results of a significant number of patients appear to be negative while there may be symptoms of infecti...
متن کاملBiomedical Evaluation of Cortisol, Cortisone, and Corticosterone along with Testosterone and Epitestosterone Applying Micellar Electrokinetic Chromatography
The validated micellar electrokinetic chromatography (MEKC) was proposed for the determination of five steroid hormones in human urine samples. That technique allowed for the separation and quantification of cortisol, cortisone, corticosterone, testosterone, and epitestosterone and was sensitive enough to detect low concentrations of these searched steroids in urine samples at the range of 2-30...
متن کاملCOMPARATIVE EVALUATION OF QUANTITATIVE PROTEIN MEASUREMENTS IN 8-12 AND 24 HOUR URINE SAMPLES FOR DIAGNOSIS OF PRE-ECLAMPSIA
ABSTRACT Background: In this study our purpose was to determine whether 8 and/or 12 hour urine total protein values correlate with the 24 hour value to confirm the diagnosis of pre-eclampsia. Methods: The study population included 70 inpatients with hypertensive disorders of pregnancy. Patient's urine was collected over 24 hours with the first 8 hours, next 4 hours, and remaining 12 hours in s...
