High court Judge Isaac Lenaola directed the former MP to go at the offices of the Government chemist at Kenyatta National Hospital for the exercise.
“Muiruri has argued that he has presented himself for DNA testing before. However, having found that the best interest of the child is the paramount principle in all matter involving children and noting that on the two prior occasions the DNA testing was not carried out, I direct that they undergo the same,” he ruled.
He will be required to undergo the test jointly with the woman; Joyce Wanjiku and the said baby.
Muiruri has consistently maintained that he is not the biological father of the baby. They were given 14 days to take up the exercise.
“Both parents should make themselves available for the DNA testing at the Government Chemist at a date to be agreed upon and in any event within 14 days,” Lenaola directed.
He said each party will meet the cost of the exercise.
Muiruri had moved to the High Court after a lower court directed that he undergo the test which he argued it had violated his rights to privacy.
Judge Lenaola however said the child had the right to know his parents.
