Brief Answer:
amniocentesis next step.

Detailed Answer:
Hello,
The reports indicate low risk for downs syndrome and negative neural tube defect but trisomy 18 risk is fairly high , so the next best step would be to undertake an amniocentesis procedure where foetal cells can be subjected to karyotyping and it can be conclusively deduced of the foetus has trisomy 18 or not.

Detailed Answer:
Hello,
The test is indeed related to age yes, but the main calculation is based on gestational age and biparietal diameter of the foetus.
In any case amniocentesis is the only option for conclusive results, rest all would just be speculations, though you may opt for a repeat quadruple test again.
