The only exceptions are as follows:
1. The sample provided by the customer does not contain enough DNA to generate a profile. A new sample will be requested.
2. Prenatal blood sampling, this test is new, and it does not currently have population information gathered enough to generate a paternity index of 10,000. Once the population databases are completed, we will offer this type of guarantee on these tests also.
3. Another kind of test is done besides paternity, such as a family study. We can not offer this guarantee in these situations as there is too many different situations where DNA testing of any kind cannot reach a paternity index of 10,000.
