Brandon Howard, with Corey Feldman (L) and Alki David (R), takes a DNA test to determine whether he is Michael Jackson’s son

*The man who conducted the DNA test on Michael Jackson’s dental mold tells TMZ that the lab results showed zero DNA on the item.

A manager at DNA Truth 4 U lab tells TMZ that last month, surrogates for shipping heir Alki David 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 Michael’s brothers 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 claims the Ireland lab recovered DNA from the mold and then determined there was a DNA match with B Howard.
