Blood or Hair?

The Global Testing Labs range of tests includes a choice of two methods, hair or blood in order to get the most accurate results available. Our hair tests take a snapshot of your health at one moment in order to give us the immune-mediated intolerance information held within. This includes which items have caused a reaction following exposure. We can also reverse the hair test to see which items your sample is lacking, giving us the data for our deficiency tests and helping you become healthier.

Our blood test gives us 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 allergy and intolerance results which are compiled into one easy to understand report. This pain-free prick test is quick and easy and gives accurate results.

A food intolerance can take up to 72 hours to occur following exposure to the item, whereas an allergy will cause you an immediate reaction. If you’re looking for the best all over body examination, the Allergy & Intolerance Prime 110 is right for you.

Frequently asked questions

How do I take a hair sample?

The safest way to take a hair sample is to ask someone else to help you. First, brush your hair upwards to reveal the root area at the back of the head, then holding a small amount of hair between the finger and thumb, cut the hair as close to the scalp as possible. If you do not have anyone to help you, try using a mirror, which may help ensure you avoid injury.

My hair is very short, can you still complete the tests?

The hair sample does not have to be from the head; we can test hair from any part of the body including leg, arm or chest.

How do I take a blood sample?

Each Blood Test comes with step-by-step instructions to help you through the process. The sample is collected following a small lancet prick and your sample collected on a blood spot card.

How long will it take to get my results?

7-14 working days from the date that we receive your hair sample and test submission form. Please allow for postage time also.

How do I contact Global Testing Lab?

Please contact us via email on [email protected]. Our customer service team works 24 hours a day, 5 days a week to ensure you never have to wait long.
