BACKGROUND: Although colonoscopy-based screening has proven to be highly effective in detecting colorectal cancer (CRC), participation rates remain disappointing. Development of CRC is associated with a number of genetic or somatic mutations. New, non-invasive stool tests are currently being developed based on the detection of these alterations. We investigated if a non-invasive stool assay can offer sufficient sensitivity and specificity to supplement colonoscopy-based screening. METHODS: We compared a combined stool assay, which incorporates fecal occult blood testing (FOBT), quantification of human DNA (hDNA) as well as detection of genetic mutations of KRAS and BRAF (Combined DNA stool assay), with commercially available FOBT and M2-PK tests in a multi-centric six-armed pre-clinical case cohort study...

BACKGROUND: Gonadotropin-releasing hormone stimulation test is a gold standard for evaluating the function of the hypothalamic-pituitary-gonadal axis (HPGA) in children. These tests are usually uncomfortable because of multi-venipunctures. A urine specimen is a good alternative because it is noninvasive and convenient. More studies have shown the correlation between sera and urine LH and FSH levels under different physiological and pathological conditions. METHODS: The study investigated the dynamic trends of urine LH (uLH) and FSH (uFSH) assayed by immunochemiluminometric assays (ICMA) during triptorelin stimulation tests in girls...
