If you doubt the integrity of your partner, do yourself a favour and buy an online DIY paternity test to check if your partner is cheating on you.
The company easyDNA.com.au claims its DNA profiling can be performed on chewing gum, licked stamps, razor shavings, toothbrushes, toothpicks, cigarette butts, tissues, handkerchiefs, trimmed finger or toenails, dental floss, hats, caps and bandannas.
It says the test guarantees up to 99.9999 per cent probability if the man is the biological father and 100 per cent if he is excluded.
However, medical experts are questioning the accuracy of the tests.
"Genetic tests can be incredibly complex and difficult to interpret and have far-reaching consequences, so there are real risks of misunderstanding if users aren't appropriately informed," The Age quoted Australian Medical Association Victoria president Dr Harry Hemley, as saying.
"I'd be concerned with people buying tests online without understanding the nature of the test and the quality of the testing," Hemley added.
Also, the Family Law Act states that only tests undertaken by accredited labs are legally acceptable and easyDNA is not one of them.
easyDNA's Mandy Hughes said that while the company was not NATA-accredited, its US lab was accredited by US authorities.
"These results are not explained, nor do they provide any form of contextual interpretation. So even though there may be the potential for the recipient of the results to suffer extreme emotional harm, there is absolutely no level of scrutiny of these services," NATA's Maritta Parsell said.
"The information from the DNA tests is very sensitive and can be misused," Victorian Health Services commissioner Beth Wilson said.
"Distress can be caused where incorrect results are given," she added.
