I am highly suspicious of Lyme but my doctor told me that my western blot shows an inactive infection. And yet my symptoms persist...

My ELISA was 1.37H

I was negative for all IGG bands, but I tested "reactive" for IGM band 41 KD. It was done by Quest labs about a month ago.

I know that's not enough for a "positive" reading. But what does it mean to have the 41 KD band? Is it just a false positive, or could it be from a similar pathogen like Babesia?


To further complicate things, I was on antibiotics (Cipro and amoxicillin) for about 10 days prior to the test. Does anyone know if this could affect the results?


Any insights are appreciated. This is all just so incredibly frustrating and confusing.

[confused]

Band 41 is only cross reactive for a type of gum disease. Many lyme patients have that as their first band to show up, so don't ignore it!!

Skip the test from Quest and find a dr who will run a Western Blot from Igenex Lab in CA. It will cost you about $200.

I too had a Quest Western Blot, only that I consider myself very lucky as IgM band 23 was positive.

That's it...No other bands. However, I did have 54 out of the 75 symptoms on a Lyme symptom list

And had already been tested for everything else under the sun...Ana, RA, HHV-6, EBV, CMV, etc.

I did not know about Igenex at the time.

Wish I did.

Yes, antibiotics can alter your test.

Igenex recommends being on them for 28 days prior to testing, with a ten day break before pulling the blood.

This supposedly increases the chance of more positive bands showing up,

Due to bacteria die-off and triggering of your immune system. (I believe)

Remember too, that Lyme is a Clinical Diagnosis.

There are people here who have been negative via Western Blot and have Lyme disease.

Get the right test done and find a Lyme Literate Medical Doctor.

BTW, I know of a family (4 members) who all had Quest and LabCorp Western Blots done that were
completely negative.

All were CDC positive via Igenex Wester Blot.

And before someone can say that no one has a negative Western Blot via Igenex, one of my neighbors did.

41 is not specific for Lyme disease but you don't need a positive test to have Lyme disease.

It sounds like your doctor is not "Lyme Literate" so I would find an LLMD!!!

I don't know whether you have Lyme or not.

Good comments above!!! Would listen to them!

To learn more about the WB do a search here with "Western Blot" and it will pull up multiple good threads!!!
Best wishes,

Yes, I'd get tested by IGeneX.

I know several people who have had negative IGeneX Western Blots ... they had some positive bands, but not enough to be a positive.

They're all getting treated for other issues, but will eventually get to the Lyme, and probably retest ...first the mercury and candida ... but, yes, there are IGeneX negatives.

I have a negtive Igenex test, but I am still being treated for Lyme, with a clinical dx. I am responding, and herxing, so I have no doubt it's what I have.

Thanks to everyone for their helpful responses! I'm so glad I found this board. I have an appt with my ID Doc on Monday and will definitely insist on the Igenex test. (I expect this will take some convincing.) I assume they test for other tick-borne stuff too?

Thank goodness, I was able to get an appt with an LLMD, only 10 days away.

Can someone clue me in: what is herx-ing? An adverse reaction to antibiotics? I feel scared.

Ditto to that!!

We "herx" when the antibiotics kill the spirochetes. The spirochetes throw off toxins when they die.

It's the toxins that make us feel even worse than before.

I'm confused about the Western Blot in terms of it always showing positive if you've ever had Lyme; is that true, and if so, how can you tell if you have Chronic Lyme or not? Especially if the symptoms are coming and going. This is happening with my son.
 
Posted by Geneal (Member # 10375) on :
 
You need to call Igenex and order the test kit for Lyme.

It doesn't cost anything to get, but it will cost 190.00 when you send it in.

It takes about 3 days for it to get to you via mail/fed-ex.

Any MD can sign the order for the test.

The basic IgM and IgG Lyme test is test numbers 188 and 189.

I believe (from research done on Western Blot)

That as time goes by, the less likely you are to have a "positve" Western Blot for Lyme disease.

Sometimes IgM bands are more indicative of a long standing infection than a recent one.

That is why you need a Lyme Literate Medical Doctor.

For me, as I never saw a tick and never had a rash, it has been

Difficult pin-pointing just about when I may have contracted Lyme.

However, as my memory improves, I believe it to have been the month I got pregnant with my second child (July of 2002).

That is when my Ob-Gyn believes I may have had West Nile disease, however, I did not have fever.

Please get to a LLMD.

Hugs,

Geneal

My first lab tests came back quite positive, and neither were from IgenX. I guess I should feel "lucky" to have been so easily diagnosed, isn't it? As Dr. H puts it: I hit Lyme Disease Bingo. On the WB, among several other bands, the following showed up: #34,39, 93 (and 41 also). These were done at a lab in Massachusetts. So the good news is that I never had to convince anyone that I might have undetected Lyme--it was easy to detect, once I was tested!

I agree, it's quite frustrating to not know when I first contracted the disease. I've had a handful of tick bites through the years, was twice treated with three days of ABX 'as a precaution', both times without having any testing done. I didn't know any better at that time.

I could certainly have had Lyme for a long time. Who knows? It's one of the mysteries of life for many people with Lyme Disease I guess.

My husband was first diagnosed about 8 years ago, and received about 3 weeks of treatment. He was subsequently treated about 3 other times over the next 3-4 years for "relapses", with about 4 weeks of abx. He just had a "routine" Western Blot done at his annual physical. He is still having symptoms. It was done by Quest, in Massachusetts, and showed:

IGG: 18, 23, 28, 30, 39, 41, 58, 66, and 93
IGM: 23, 41

So clearly it's still active by that test, right? But my son had a test recently, and it showed:

IGG: 23, 41

IGM: 23

His doc says it's becasue he had Lyme about 4 years ago. Could that be true? I dont' think so, but it is confusing as his symptoms come and go.
