https://www.functionalnutritionanswers.com/what-is-the-best-food-sensitivity-test/"..........Similar to MRT, the aim of ALCAT is to measure the amount of mediators released by white blood cells in response to different food antigens.
It was actually developed in the 80’s by Dr. Pasula (the same guy who created MRT), but Dr. Pasula eventually separated from that company and created MRT using newer technology for more accurate results.
How does it work?
ALCAT works much in the same way as MRT. The client orders the test through a healthcare provider or directly from Cell Science Systems (North America only), gets their blood drawn locally, and mails the sample overnight to the lab.
Like MRT, the patient’s blood sample is exposed to a variety of antigens and monitored for changes in cell sizes.
However, ALCAT uses an older impedance technology, which is not quite as accurate as the more modern (but patented) three-dimensional ribbon impedance methods used by MRT (69)................."

However, a larger testing panel also introduces more opportunity for error, false-negatives, and false-positives that may hinder someone’s attempt at an elimination diet.
