A huge white sign with the words "Who's your daddy," on Tanque Verde Road has caught the eyes of many folks on the Eastside of Tucson.
The sign is a way to market paternity and DNA tests provided at Any Lab Test Now.
"This was kind of a fun spin," says Laurie Wallner, owner of Any Lab Test Now. "Making light of something that is a real serious problem for the folks that need paternity and DNA testing."
In the beginning of the year, the lab decided to post the sign at the entrance. Since then, paternity and DNA tests have increased by 137%.
The lab offers two tests for families - an informational and legal test.
An informational test allows people to get a peace of mind and a legal test can be used in court which is the one a Tucson mother is using after being threatened to be taken to court.
The mother, has chosen to stay anonymous and says she wants to know if her two little daughters, age one and four have the same father.
The mother says that she and the father of her oldest daughter decided to end their relationship. Soon after, she began dating her coworker.
The relationship with her coworker ended, as well.
After some time, she returned to her ex-boyfriend. During that time she found out that she was pregnant with her youngest daughter who is now a year old.
"After my second daughter, they started stalking me on Facebook and they started saying that he looked like my daughter," says the mother.
After being bullied and harrassed on social media she wanted the answers for herself.
She tells KGUN 9 that a paternity test was taken previously that proved that her two little girls had the same father. But now, the father of her oldest daughter wants to know if he is the father of the one-year-old, as well.
"They're threatening to take me to court," says the mother.
The mother says she doesn't know what the results would be and she is hoping that both of her girls have the same father.
The children and the mother went to Any Lab Test Now to get swabbed.
"When it comes to paternity testing and DNA you either get a really joyous moment when you give them the results or you can see their heartache," says Wallner.
Nearly two weeks after the swabs were taken -- the results came in.
The test results showed that both her daughters had the same father.
The mother says she's just relieved and happy to end this chapter.
