Is a peternity blood test taken 22 yrs ago as effective as a dna test today?

No.: Blood testing just looks at blood type, and while a child's blood type has to come from two specific blood types, many people have the same blood type (ie many options would still exist for the father). Today's dna testing uses cheek swabs and establishes a more exact dna pattern - different companies tout different success rates but most are >98%.

Depends: If paternity was excluded with blood group tests, there is no need for DNA test. If it was not excluded, than DNA testing is nearly certain to exonerate a false accused man with far greater sensitivity.
