In spring 1985, forensic DNA testing was four years away from its first use in the American court system, Murch said.
Murch's testing looked at blood enzymes - different people have different types of enzymes in their blood, he said. The method was far less precise than DNA testing, he said.
In response to a question from a juror, Murch said the enzymes in the vaginal material matched the enzymes in Eastburn's blood, but he found no sign of the enzymes from Hennis' blood. The enzymes in Hennis' blood are found in 1.4 percent of the population, Murch said, and were different from the enzymes he found in Eastburn's blood.
Murch said his enzyme testing could not say whether Hennis was the source of the sperm cells in the vaginal material. He was not asked by prosecutors, defense lawyers or the jury to explain further.
DNA testing is many orders of magnitude more reliable than the enzyme test, Murch said. Originally, DNA testing of sperm required about one million sperm cells, Murch said, "and now it's down to one or less."
The test you are referring to was conducted in 1985. Blood enzyme testing was done then. Now, DNA testing is done and is much more reliable than the enzyme test. The DNA test matched Hennis to the sperm cells found in vaginal tissue from Eastburn.

The above link is about the DNA match.
Prosecutors presented a final witness Monday in the case against 51-year-old Master Sgt. Timothy Hennis. Jennifer Hopper, a former forensic analyst with the State Bureau of Investigation, testified that DNA she tested in 2005 matched DNA collected from Hennis in 1985.
Hennis faces charges of premeditated murder in the 1985 stabbing deaths of Kathryn Eastburn and two of her daughters, 5-year-old Kara Sue and 3-year-old Erin Nicole.
Hopper said sperm on a vaginal swab taken from Eastburn's body matched Hennis' DNA profile. Using a database that mirrors the population of North Carolina, she said the odds that the sperm came from another white man were 12.1 thousand trillion to one.
