Can the NIFTY test be inconclusive?
Yes. In 1-2% of the cases the NIFTY test gives invalid results for the maternal blood contains an insufficient amount of fetal DNA.
In such cases, if the gestational age is less than 17 weeks, blood sampling should be repeated, and since the amount of fetal DNA continuously increases as the pregnancy gets more advanced, this repeated blood sampling is expected to produce valid results.
Repetition of an inconclusive NIFTY test is free of charge! If the repeated test also gives inconclusive results, the patient may require the refund of the entire price.Can it be used to determine the gender of the fetus?
