Physicians Lab is a state-of-the-art clinical testing laboratory, offering the most comprehensive, advanced, accurate and convenient assessment of a patient’s hormones, hormone metabolites and other essential bio-markers. Physicians Lab employs state of the art laboratory instrumentation and testing methods. Our intricate instrumentation are the finest available to quantitatively measure and distinguish analytes of similar structures, masses and binding behaviors. Physicians Lab uses Liquid Chromatography-Tandem Mass Spectrometry (LC-MS-MS) technology. LC-MS-MS offers healthcare providers and patients the most accurate, precise and reproducible testing methods and results. Urinary testing has emerged as a preferred method of assessing a patient’s hormones, their downstream metabolites and an integral cornerstone to assess and monitor hormone replacement therapy protocols. Physicians Labs’ unique 24 hour, 5-point patient collection method is an easy approach to normalize the fluctuations most patients experience in their hormone levels, throughout the day. Hormones and their downstream metabolites can only be measured in urine and cannot be assessed in blood or saliva. Through hormone metabolite testing, Physicians Lab affords healthcare providers genetic and lifestyle bio-markers that allow for personalized and precise therapies, lifestyles and hormone balance that is specific, to each individual patient’s needs. Physicians Lab has developed the first At-home Myostatin / Follistatin lab test. We deliver step by step guidance, from the comfort and convenience of each patient's home. Once each patient’s urine samples are collected and returned to our lab, we operate under the highest standards of quality control to guarantee precise, accurate and timely results are delivered to their healthcare provider.
