Have you used a home testing kit for a medical diagnosis?

COVID-19 RATs are an example of these types of tests but we are interested in the many others on the market.

The University of Wollongong is conducting a small study about them and we'd like to hear from you if you have used one or considered using one.

Simply complete a short survey at:

From here, we may invite you to take part in a paid interview.

Sample required?
A blood sample drawn from a vein in your arm
 
Test preparation needed?

What is being tested?

This test measures the amount of IgE anti-alpha-gal antibodies in the blood. Anti-alpha-gal IgG antibodies are present in all people and are not associated with any form of illness. IgE anti-apha-gal antbodies are much less common and are associated with allergy to red meat in the form of delayed (4-8 hours) systemic allergic reactions including anaphylaxis after eating red meat. The primary cause of this allergy is a reaction to be being bitten by a tick. In Australia the common paralysis tick Ixodes holocyclus is the cause. In the US and Europe different types of ticks can cause this disease.
 
How is the sample collected for testing?
A blood sample is obtained by inserting a needle into a vein in the arm.
 
Is any test preparation needed to ensure the quality of the sample?
No test preparation is needed.
 

The Test

How is it used?

The anti-alpha-gal test is used to diagnose red meat allergy in people suspected of having this condition. IgE antibodies to red meats such as beef, lamb and pork may also be ordered at the same time.

When is it requested?

The test is usually requested when people develop symptoms after eating red meat.

What does the test result mean?

When significant amounts of IgE anti-alpha-gal are present in the blood, then allergy to red meat can be diagnosed. 

Is there anything else I should know?

People with red meat allergy are also likely to be allergic to the cancer drug Cetuximab.
