Has anyone done the sneak peak test and had INACCURATE results ?

Went to a boutique and had the nurse draw my blood and send the tube out overnight , but have been reading some reviews saying their results came back inaccurate ?

All the reviews that are inaccurate seem

To be people who drew their blood themselves ( and apparently you can’t have any male dna on the test tube and that’s where the false positives come into play)?

Any comments are welcome💙💓
