I had quit smoking for 2 weeks they tested my blood for nicotine will it still show up in the test?

Not likely: If you have not been exposed to second hand smoke and did not take nicotine in any other form, e.g., nicotine patch or gum, the result should be clear. While you have managed to be smoke free for two weeks, you will do a world of good for yourself by not smoking at all. I wish you the best in your efforts to quit smoking.

Possibly: “When someone stops using tobacco and nicotine products, it can take more than two weeks for the blood level of cotinine to drop to the level that a non-tobacco user would have and several weeks more for the urine level to decrease to a very low concentration.” REF: http://labtestsonline.org/understanding/analytes/nicotine/tab/test/
