sorry about ur situation.. but no.. because dna test may take around 3days.. and its so expensive that may reach above 1000$ depending on the country or hospital...! i dont think dude.. try doing some blood test ABO testing for a cheaper one(though it maynot help)... but example if u are blood type B and ur wife is B.. ur child myt be B,or O.. but if it happened to be AB or A, that may be not ur child...
