Inflammatory diseases, infections and chemical imbalances can result in similar symptoms, providing a red flag but also a false alarm. On top of this, many of these disorders can be effectively treated through medication and other treatments. Although a spinal tap, or lumbar puncture, can be uncomfortable, it is an essential step in diagnosing MS. This test involves the removal of a small sample of fluid from the spinal canal that is taken for analysis in a laboratory. The spinal tap is often a component in how to diagnose multiple sclerosis, because the fluid may show abnormalities in white blood cells or proteins that may indicate a malfunction of the body's immune system and the presence of the disease.

That's because patients can still register a normal MRI and still have MS. As doctors are learning more about how to diagnose multiple sclerosis, this test is providing additional information to get an accurate determination of the disease. The procedure is painless and involves the use of visual or electrical stimuli to measure the electrical... 

Now, please write a short abstract for it in Indonesian. Abstract:
