These tests first appeared in the United States in the early 2000s and were initially controversial, but later serious studies were carried out, leading to improved procedures and very reliable results.
After a number of tests, a serious study was carried out on a sample of 10,000 people in the US between 2005 and 2007 over a period of 6 months. Each time, the results were conclusive, with a reliability rating of 87.9% for the sample.
The MYTRUECOMPANION test includes over 37 criteria, a first in Europe.
Ratings from the MYTRUECOMPANION test that are higher or equal to 7 (on a scale from 1 to 10) resulted in marriage within two years of the test, just as ratings equal or lower than 3 resulted in a separation within 6 months of the test.
