Is it accurate to take a pregnancy test 3 weeks after sex (1 week after a missed period)?

Yes, test should be positive by that time if conception does occur with the sexual encounter.

Yes. Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
