Would getting a blood test for pregnancy be accurate 16 days after my last sexual encounter?

If positive. If the result on a correctly done test is positive at 16 days post-coitus, it would be accurate. If the result is negative, you should repeat the test in a week or so, unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex.

Can I trust the results of a qualitative blood test 21 days after sexual encounter?

May be. The results will be accurate but may not answer your question. Did you miss a period? If not you may have tested too early to detect pregnancy. Even the blood test should be done a day or two after missed period. A negative result on a test done too early does not rule out pregnancy. Read more...
