Jay KlauminzerThe right test for you!
The Global Testing Lab range of tests includes a choice of Hair and Blood testing in order to get the most accurate results available and help you. Our aim at Global Testing Lab is to give you the required information you need to make positive changes to your wellness and life.
Ranging from the latest biotechnology to test hair samples to IgG4 and IgE blood antibody testing, our UK labs provide a fast and effective alternative to long waiting times at the GP.
If you suspect that your diet may be affecting your allergy or intolerance symptoms then you should order either an allergy or intolerance test. This will help you alleviate your symptoms.
Hair Tests
Our bioresonance hair testing takes a snapshot of your health at one moment in order to give us the immune-mediated intolerance information held within. You can discover which food items are causing your intolerance reactions. We can also reverse the hair testing process to see which items your sample is lacking, giving us the data for our deficiency tests.
Blood Tests
Our blood intolerance and allergy test provides us with the data following the extraction of the plasma from your small blood spot sample once it arrives in our lab. The enzyme immunoassay for in-vitro testing offers you accurate intolerance and allergy testing results which are compiled into one easy-to-understand report. This pain-free finger prick test is quick and easy, providing us with accurate testing results.
