What is the standard range of Lyme disease?

Borrelia burgdorferi antibody enzyme immunoassay (Lyme index value) : < 0.9 = negative. 0.91-1.09 = equivocal.

What is the best clinical marker of Lyme disease?

Enzyme-linked immunosorbent assay (ELISA) test. The test used most often to detect Lyme disease, ELISA detects antibodies to B. burgdorferi. But because it can sometimes provide false-positive results, it’s not used as the sole basis for diagnosis.

How accurate is a Lyme titer?

In the first three weeks after infection, the test only detects Lyme 29 to 40 percent of the time. (The test is 87 percent accurate once Lyme spreads to the neurological system, and 97 percent accurate for patients who develop Lyme arthritis).

What is the gold standard test for Lyme disease?

Serologic tests are the gold standard Direct tests lack sensitivity for Lyme disease; hence, serologic tests remain the gold standard. Currently recommended is a standard 2-tier testing strategy using an enzyme-linked immunosorbent assay (ELISA) followed by Western blot for confirmation.

What are the 5 bands of Lyme disease?

Some Lyme specialists and scientists believe that there are five very specific bands on the Western blot test that are highly indicative of Lyme disease: band numbers 23, 31, 34, 39 and 93. If any of these bands are positive and the patient is experiencing symptoms of Lyme disease, they may feel treatment is warranted.

What is band 93 Lyme specific?

Optimal Result: 0 – 0.001 Units. Two types of antibodies are detected in the Western blot test. This particular marker is called 93 KD (IGG) Band and hence is a IgG antibody marker. IgG antibodies are a sign of an older infection.

How long do Lyme titers stay positive?

In the absence of treatment, IgM titers usually peak 6-8 weeks after infection and disappear within 4-6 months, although levels sometimes remain elevated for several months or years. IgG antibodies are typically detectable within 6-8 weeks after infection, peak within 4-6 months, and remain elevated indefinitely.

What is the most accurate Lyme disease test?

A blood test does not only detect Lyme disease; it is the most accurate and preferred test for diagnosing the disease. If a patient with Lyme disease shows signs that the central nervous system has been affected by the disease, western blot testing on the cerebrospinal fluid (CSF) can be performed.

Is Stage 3 Lyme disease curable?

Stage 3 (late disseminated) Lyme disease is also treated with various antibiotics: For Lyme disease that causes arthritis, 28 days of oral doxycycline, amoxicillin, or cefuroxime is prescribed. Additional courses of antibiotics may be necessary, depending on the severity and persistence of your symptoms.

Can Stage 2 Lyme disease be cured?

Using Antibiotics to Treat Lyme Disease If you already have stage 1 (localized) or stage 2 (early disseminated) Lyme disease with the telltale bull’s-eye rash but no other significant symptoms, your doctor will most likely treat you with oral doxycycline, amoxicillin, or cefuroxime for 14 to 21 days.

How many bands have to be positive for Lyme?

In addition to testing for antibodies, it reports reactivity against a panel of 10 different proteins found on the Lyme bacteria. According to the CDC, 5 of the bands must be positive for an overall positive, reportable Western blot test result.

How many bands do you need positive for Lyme?
