Can a positive Lyme disease western blot strip test be mistaken for another disease?

Can a positive Lyme disease western blot strip test be mistaken for another disease?

Yes!: No lab test is perfect, including the westen blot for lyme. There is an approximately 4% chance of a positive being a "false positive" test. There is also an approximately 20% chance of false negatives, someone with lyme not having a positive western blot. This is why lyme is ultimately a clinical diagnosis, with labs used to support a diagnosis. Other tests may also be useful. Please see comment:. ...Read more

You have to reach a certain 'threshold' with Lyme testing because there could be some cross-reactivity coming from these other types of bacteria. The immune system is extraordinarily complex ...Read more

Not enough info: This test is not evidence of lyme but also not proof you don't have it! ultimately lyme is a clinical diagnosis. 20-30% of those who have it never have a positive western blot. It's really important that the test include the 31 & 34 bands & most labs don't check it- igenex is the best lab for a thorough test. See a doc who uses igenex as that is someone able to make a proper diagnosis.See comment:. ...Read more

Tested positive for Lyme disease IgM but my western blot test came back negtive?

Tested positive for Lyme disease IgM but my western blot test came back negtive?

Then it's not Lyme: Lyme disease can be tricky -and you want to make sure you see someone like an Infectious Diseases doctor who knows how to treat it. The diagnosis is actually based on clinical findings, and the lab testing is generally 'supportive'. Since you're Western blot is negative, then it's very unlikely you have Lyme. There are other diseases that could cause 'Lyme-like' symptoms -and good to get evaluated ...Read more

What to do if i did a Lyme disease test and it showed IgG p58 ab. Positive a can you explain what that means?

Nothing by itself: A single positive IgG band means nothing. Was the screen positive? How many other IgG and IgM bands were positive? You should discuss all of this with the doctor who ordered the test. ...Read more
