Kenya DNA Report 2023

Out of Every 30 Men who Undertake a DNA Test, 10 are Raising Children that are not Biologically Theirs

In this report, we review 6,169 DNA profiles from samples obtained for relationship testing in Kenya. We provide information about the most common DNA tests conducted, preferred sample types, ethnic distribution of tests and outcomes, and important statistics. For the first time also, we have determined allele frequencies of the core FBI STR markers in the Kenyan population and calculated statistical parameters of importance in forensics.

DNA Paternity test outcomes in Kenya

40% of all DNA Tests in Kenya were Carried out by Kikuyu Men

Nearly 40% of all tests were carried out by Kikuyu men. 83% of all DNA tests in Kenya were carried out by Kikuyu, Luo, Kamba, Luhya, Kalenjin, and Kisii Men. Luos (12%), Kambas (9.5%), Luhya (9.0%), Kalenjins (6.7%) and Kisii (6.0%) followed in that order. If you exclude Caucasians and Non-Kenyan Africans, the rest of the 36 tribes accounted for less than 10% of all DNA tests conducted in Kenya.

94% of all DNA tests are Carried out to Determine Paternity

Paternity tests are the most popular type of DNA tests and account for 94% of all DNA tests

Where parents’ samples are unavailable, majority of people prefer to check for paternity using their brothers’ or sisters’ samples

Single profile tests are conducted for purposes of DNA Banking or comparison with tests from other labs or banked DNA Profiles. Single profile tests were the third most popular DNA tests after Siblingship tests and accounted for 1.7% of all DNA tests.

Least popular DNA tests are cousin tests, Y chromosome tests and grandparent tests in that order.

Very Few women take part in DNA Tests and maternity tests accounted for only 0.8% of all DNA Tests. All women who suspected that their children had been switched at birth were proven wrong

Paternity of Unborn Children

Paternity of children can be ascertained before they are born. The invasive prenatal DNA test is done to determine if a particular man is the biological father of an unborn child and is performed between week 16-20 of pregnancy. It is 99.99% accurate and is based on comparison of 24 genetic markers between the mother, unborn baby, and the alleged father. Samples used are amniotic fluid from the mother and alleged father's sample (mouth swab) The Non-invasive prenatal (NIPT) DNA test determines the paternity of the unborn child from as early as week 8 of pregnancy after the last menstrual period. Unlike the invasive prenatal DNA test, the NIPT test is 100% safe to the mother and child because fetal cells are obtained from maternal plasma and there’s no need of amniocentesis.

NIPT paternity test is more popular than the invasive test

Even though the NIPT Test is 4 times more expensive than the Invasive prenatal Test, more women prefer the NIPT Test.
