Introduction 24-hour urine hormone testing has long been established as a reliable method for evaluating the production of steroid hormones and their metabolites. In clinical practice, these levels correlate well with symptoms as well as with doses of exogenous hormones and symptom control. (1-3) Serum hormones are limited in their utility by comprising only a
• Xanthurenic acid (XA)—a tryptophan metabolite—is high in serum in gestational diabetes • Xanthurenic acid binds insulin, impeding it’s action • Vitamin B6 lowers xanthurenic acid levels to normal • In two 1970s research studies, 86% and 100% of women with gestational diabetes normalized their blood sugar in two weeks by taking vitamin B6 •

Objective To compare type II collagen degradation using a new urinary specific marker in patients with rapidly destructive and those with slowly progressive hip OA. Methods Twelve patients with rapidly destructive and 28 patients with slowly progressive hip OA were included in a prospective, cross sectional case-control
May 1st, 2018 Meridian Valley Lab now measures Xanthurenic and Kynurenic Acids to provide clinical information regarding the patient’s inflammatory and vitamin B-6 status. The function of the Kynurenine Pathway, which generates Xanthurenic and Kynurenic Acid, is affected by hormone status. A deeper understanding of both of these biomarkers, provided at MVL, provides an “early
