There are many medical tests that may be necessary when a doctor is trying to figure out what is wrong with a patient. Some of these medical procedures can be uncomfortable but ultimately save the person's life. However, these tests must be undertaken with care to avoid doctor error. When doctors make mistakes, the results of the test can be inaccurate, or accurate results may be misread, causing a patient to suffer.
A spinal tap, or lumbar puncture, for example, is a common procedure that can present problems. Through this procedure, a doctor is able to analyze a person's cerebrospinal fluid to diagnose variety of conditions. The test utilizes a hollow needle, placing it between vertebrae in a person's spinal cord and drawing out the fluid.
