5.0 out of 5 stars Confusing how to read results.

S. · May 14, 2025

(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } It just seems to me how to read the test is confusing or wrong. In MOST tests the "control" line just shows the test chemicals are active. The the "test" line then shows whether it detects a substance. Here, it is the opposite!? If there is JUST the control line and nothing on the test line means it is a positive test. If there is BOTH lines in means there is NO substance detected.I think that is really weird and opposite how most other type tests are read and interpreted?

had to quit smoking for breast Augmentation and when I tell you nicotine stays in your system a full month, I mean it. a solid 4.5 week. even after I was finally able to pass, after surgery I smoked a half cig and it still showed up straight away for 2 weeks. they are very accurate.idk about vape but I smoked a half pack a day before quitting and smoked a pack a day for years.

Compré este kit para llevar un seguimiento de la nicotina en mi cuerpo ya que me tengo que realizar una cirugía y no puedo dar positivo, antes de comprar este kit tenía otro de 3 y me dieron todos negativos(era otra marca) así que me decidí por este para estar más que segura, y si lo que esperaba salió negativo también. La única queja que puedo tener es que el contenedor de recolección de orina es muy pequeño por lo demás todo bien.

I had to stop for a surgery. And of course I waited to the last week of the test. I stopped on Sunday, actually I took a couple of puffs that morning. I drank a lot of water like anyone would do and tested on Wednesday evening and I was cleaning by then. Double checked again before I got to the hospital on Friday morning to mack sure the first test was right and I was lucky that I was clean so yes I trust these. But I don't suggest anyone wait until the last moment like I did. It's not smart plus your system may not flush as quickly as mine did.
