我問過AI個醫生解讀又唔錯晒wor, 個report寫得衰, 但係的確暗示緊係無Y chromosome:
Why It Likely Means No Y Chromosome DNA While the statement alone doesn’t explicitly say "no detectable Y chromosome DNA," here’s why that’s the most likely interpretation:
Context of the test:
NIPT is designed to screen for fetal sex and sex chromosome abnormalities. If Y chromosome DNA were present (indicating a male fetus), the test would typically note it, especially in a report addressing chromosome abnormalities. The lack of any positive mention of Y chromosome DNA suggests it wasn’t detected.
Related findings:
Your query mentions a "decrease in DNA from Chromosome X," which could point to Turner syndrome (X0), a condition with one X chromosome and no Y chromosome. If no Y chromosome DNA was detected, this fits with the absence of a "quantitative aberration" in Y chromosome DNA—there’s simply none there to be abnormal.
Maternal contribution:
The test also mentions a "high possibility of maternal contribution," meaning maternal DNA (which lacks a Y chromosome, as the mother is female) may dominate the sample. If fetal Y chromosome DNA were present, it should still be detectable despite maternal DNA, since the mother has no Y chromosome to interfere. The fact that no aberration was detected reinforces that no Y chromosome DNA was found.
