Re: IgeneX tests
Mar 25, 2006
Hi All:

Prema- You are right about those results for the IgM, but there is more to the story...

I had been looking this over very closely when I got my sons results so this is fresh in my mind. The IgM is actually very important in lyme since that is what shows current infection. In Lyme the IgG show past, but possibly resolved infection. This is opposite for things like allergies. The CDC has much more stict criteria than Igenex. Also, many of these band are lyme specific like 23-25, 31, 34, 39-so you would think if you had a positive on any of those it would be a diagnosis on its own. Apparently the CDC's criteria used to be less stringent, but they have back pedaled recently so instead of making progress with diagnosing lyme we are going backwards. :confused:

Actually the CDC has more strict criteria than Igenex. For the [B]IgM[/B] Igenex considers it positive if you have [B]2 or more[/B] of the following bands present:

23-25
31
34
39
41

The CDC considers the [B]IgM[/B] positive if you have [B]2 of the following 3 bands [/B] positive:

23-25
39
41

For an [B]IgG[/B] Igenex considers it positive if you have [B]2 or more of these bands[/B] present:

23-26
31
34
39
41
93
Igenex considers the [B]IgG[/B] equivocal if you have one of these bands present by itself with the exception of band 41 since it can be found in all spirochetes.

The CDC criteria for [B]IgG[/B] is:
that [B]5 of the following bands must be present[/B]
18
23-25
28
30
39
41
45
58
66
93

CDC considers it negative if less than five of any of these bands are positive.
The CDC also disregards bands 31 and 34 since they were used to make the vaccine that has been pulled off the market, even if you have not been vaccinated they will not count those bands if you react to them.
