PrenatalSAFE®Karyo results will tell your healthcare provider whether too few or too many copies of the chromosomes being tested for are present. If a chromosomal abnormality is detected, follow up testing (such as amniocentesis or chorionic villus sampling) is recommended to confirm the result.
Our reports will include one of three possible results:
The test result means that PrenatalSAFE®Karyo test identified too many or too few copies of one of the chromosomes as seen on the report. This can indicate either a trisomy, or a sex chromosome aneuploidy, or a segmental chromosomal abnormality.
No Abnormality Detected
This test result means that PrenatalSAFE®Karyo test identified the expected number of copies of chromosomes reported.
PrenatalSAFE® Karyo is a screening test, it does not aim to provide diagnostic results.
A negative test does not ensure an unaffected pregnancy. Chorionic villus sampling and amniocentesis provide definitive diagnostic information, but may pose harm to the fetus.
This test result means that PrenatalSAFE®Karyo test identified more copies than expected of the chromosomes reported. Your provider should follow up on this result to obtain more information.
There is also a chance that the sample submitted will not return any results; in this case a second sample may be requested to repeat the test.
