How to Find a Lab to Test for Filariasis

Globalization has allowed once rare parasitic diseases to increase in range and frequency, and many individuals traveling to and from certain countries find themselves in search of laboratory testing to confirm or exclude a number of possible diagnoses. One such parasite, Wuchereria bancrofti, is the nematode (roundworm) responsible for lymphatic filariasis, or elephantiasis, a devastating disease that obstructs lymph channels and results in severe swelling, particularly of the lower extremities. Fortunately, this disease is treatable if the offending parasite is identified in a timely fashion.

Instructions

• 1

  Recognize the symptoms. The symptoms of filariasis infection include extremity swelling, lymph node swelling, breast swelling, scrotal swelling and, more rarely, wheezing, coughing or shortness of breath.

• 2

  Find a physician. A good option is to begin with your regular family doctor. Explain your symptoms and, if applicable, your travel history or other unusual exposures. She should be able to draw blood samples or refer you to a laboratory that can.

• 3

  Understand the other testing options. Diagnostic measures include blood testing to detect the parasite or an immune response to the parasite; lymph node aspiration to identify the parasite; and medical imaging to identify parasitic calcium deposits. The preferred option is antigen testing via a blood sample.

  Follow up on your test results. Be proactive regarding your health care. If you do not hear back from your physician, call her office. Understand that testing can take time, but never be afraid to follow up. It can be crucial to receiving quality care.
