Lyme Disease Testing 2

The Western Blot has traditionally been used to confirm the first (IgM) test if that one is positive. However, it reveals certain important information on its own. Keep in mind that the Centers for Disease Control and Prevention (CDC) has criteria for diagnosing Lyme based on the Western Blot. However, scientists for the CDC and others contradict these criteria and it’s not based on science, as you may think. It’s a good idea to check in with someone who is familiar with Lyme disease, and who is a member of the ILADS (International Lyme and Associated Disease Society) who can appropriately read your lab test. If ANY of the bands of the Western Blot come back positive, further testing may be necessary.
