The lawsuit states that the sperm bank's records were not electronic, and that the sperm vial numbers were written in 'pen and ink'.
The couple only learned of the mistake when, five-months-pregnant, Cramblett called the sperm bank to reserve more sperm of the same donor, and was informed that she had been inseminated by the sperm of the wrong donor.
Cramblett is now suing for a minimum of US $50,000 in damages under wrongful birth and breach of warranty, citing the emotional and financial losses she has suffered.
'How could they make a mistake that was so personal?' said Cramblett in an interview with the Associated Press. 'They took a personal choice, a personal decision and took it on themselves to make that choice for us out of pure negligence'.
'I am happy that I have a healthy child, but I'm not going to let them get away with not being held accountable', Cramblett told NBC News.
Cramblett said she and Zinkon love their two-year-old daughter, Payton, and that they bonded with Payton easily. However, the lawsuit also cited Cramblett's fears, anxieties and uncertainty about the family's future. She is concerned about raising Payton in Uniontown, a small, predominantly white community which she described as 'too racially intolerant'.
An example of racial prejudice cited in the lawsuit is Cramblett's experience when getting her daughter's haircut. 'Payton has hair typical of an African American girl. To get a decent cut, [Cramblett] must travel to a black neighbourhood, far from where she lives, where she is obviously different in appearance, and not overtly welcome'.
She is also concerned about raising Payton in her 'all-white and often unconsciously insensitive family' that often 'speaks openly and derisively about persons of colour'.
Speaking to CBS News, lawyer Rikki Kliemann explained that the case presents a 'good legal lawsuit' due to the sperm bank's negligence, but it also poses 'moral issue' as to why Cramblett is disturbed by the birth of her healthy, albeit racially mixed, child. 'The lawsuit is called a wrongful birth lawsuit... traditionally brought if you had a child that had a congenital birth defect or some kind of congenital abnormality that a doctor should have warned the parents about', he said.
'I think it's an unfortunate labeling', Kliemann adds. 'So is breach of warranty, which is a second count because breach of warranty sounds like a commodity - you bought a car and it was defective'.
Legal representatives for Midwest Sperm Bank said that the company would not comment on pending litigation.
