The man behind the Michael Jackson DNA test initially went to an L.A. lab ... and TMZ has learned the lab results showed NO DNA on Michael Jackson's dental mold.
A manager at DNA Truth 4 U lab tells TMZ ... last month Alki David's people took the dental mold to the lab, along with a water bottle, a black towel and cigarette butts to test them. Alki's people told the lab the other items contained the DNA from Jermaine and Tito.
The lab report -- obtained by TMZ -- shows the dental mold document titled "Alleged Father." The other items were all titled "Alleged Uncle."
The lab report shows NO DNA was recovered from the 31-year-old dental mold, so the test could not be performed. The only one that had any DNA was the black towel -- and it showed NO relation to B Howard. Translation -- B Howard is NOT related to ANY Jackson.
A source connected to Alki David tells TMZ ... Alki didn't trust the lab and that's why he says they went to a DNA lab in Ireland.
Alki says the Ireland lab recovered DNA from the mold and then determined there was a DNA match with B Howard.
