Available blood tests are antibody-based for Lyme disease and do not accurately diagnose Lyme disease in the first few weeks of infection. False negative tests are a problem in acute Lyme disease. Therefore, early Lyme disease is a clinical diagnosis. Recognizing signs, such as the rash, and symptoms can be vital to receiving appropriate early treatment.
