Can you do double marker test 3days after NT scan? Will it affect the results in any way? I did my NT scan & double marker test at 12 weeks.. however, due to their negligence, after 3 days I was again asked to give my blood sample for double marker test.
My results for double marker test taken after 3 days are all negative and risk ratio is also low. Even my NT scan is normal except for marginal placenta previa.
Now I am 16 weeks
pregnant.
