Dr Advait Kulkarni (Neurologist in Bengaluru) How is it diagnosed? CIDP is difficult to diagnose. It’s a rare disorder, so doctors may rule out more common diseases or disorders first before they reach a CIDP diagnosis. To reach the diagnosis, your doctor may use several tests and exams. First, your doctor will likely take a detailed medical history and ask you to explain in as much detail as possible when symptoms started, and how or if they’ve changed. For a CIDP diagnosis, you must experience symptoms for at least eight weeks. In addition, your doctor may order some tests to examine other parts of your body. A nerve conduction test can let your doctor see how quickly nerve impulses move through your body. This reading can help in the future to determine if your impulses are improving or growing worse. Likewise, a spinal fluid analysis and blood or urine tests can help your doctor rule out other possible causes for your symptoms. To know more click the link below http://www.dradvaitkulkarni.com
