This test measures the electrical activity of the muscles when they are working to contract and when they are at rest. EMG testing is used to diagnose conditions that cause muscle tissue damage or damage to the junctions between the muscles and nerves. We perform these on-site.
This test is also known as a spinal tap. A needle is inserted into the spinal canal, to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and spine. We perform these lumbar punctures here in the office on-site.
We have a small laboratory on-site that collects blood tubes for research studies. We are able to process these specimens and ship them for analysis. Our staff members are IATA certified and our laboratory has a CLIA waiver.
As part of our research studies, we collect urine specimens for routine analysis.
