Frequently Asked Questions

מצא תשובות מהירות

What does my NIPT risk estimate mean?

The risk estimate indicates the probability that the fetus has a chromosomal abnormality based on your test results. High risk suggests closer monitoring or further testing, while low risk generally indicates lower likelihood but does not eliminate the possibility.

Can this tool replace medical advice?

No, this calculator provides an estimated risk based on your data. Always consult with a healthcare provider or genetic counselor for comprehensive interpretation and medical guidance.

Which data inputs are required?

You can input maternal age, test result status, and optional raw data such as read counts or z-scores. Providing more data improves accuracy, but the calculator can operate with minimal inputs.

Is the tool suitable for research purposes?

Yes, it can be used to analyze large datasets or for educational purposes, but always verify results with clinical judgment and laboratory data.

Is this calculator compliant with healthcare standards?

It is designed as an informational support tool and does not replace professional medical diagnosis. Privacy and data security are maintained according to general online standards.
