Anybody heard of this "blood spot allergy testing"? This is a simple finger-prick blood spot test that detects allergies to foods. I found two versions which appear to test for 30 or 96 common "hidden" food allergens with IgG sensitivity. IgG antibodies are associated with non-atopic or "delayed" food reactions.
The research indicates that IgE "blood spot" yields virtually identical results to IgE serum testing for airborne sensitivities.

http://www.forresthealth.com/store/p...roductid=16340 (only tests 30 foods)
Tests 96 foods: http://www.vrp.com/ProductPage.aspx?ProdID=9840
another 96 foods, seems to include environmental allergens: http://www.vrp.com/ProductPage.aspx?ProdID=98401

Multi-lab testing options, saliva, yeast, foods, heavy metals, adrenals, etc. http://www.lavalleinstitute.com/inde...d=54&Itemid=40

I found this abstract from American Journal of Human Biology.
Abstract:Elevated circulating levels of total immunoglobulin E (IgE) are associated with both allergic disease and repeated macro-parasitic infections. Population-based research on IgE has been limited by the logistical constraints associated with obtaining and processing venipuncture blood samples. In this short report, we present an enzyme immunoassay protocol for quantifying circulating total IgE levels in capillary whole blood, collected from a finger prick and dried on filter paper. The assay demonstrated acceptable levels of accuracy, precision, and reliability. IgE remained stable at room temperature for only 2-4 days and degraded rapidly at higher temperatures suggesting that samples should be refrigerated or frozen within 1-2 days of collection. It is hoped that the relative ease of blood spot collection will expand opportunities for population-based research on IgE. Am. J. Hum. Biol. 19:440-442, 2007. © 2007 Wiley-Liss, Inc.

[Also found this "blood spot testing" for vit D deficiency. http://www.oasisadvancedwellness.com...spot-test.html ]
Here is a home test kit for airborne allergies: http://www.checkmyhealth.com/site/57...CMH-IT-MAT-001
This is all new to me and a bit confusing about the different IgG and IgE whole blood finger stick testing. Anyone have additional info or links?
Thanks, Pat
