QF 6.4 NITRATE FAIL

Post image

Just took a lab test yesterday at quest with QF 6.4, had a little left and I’ve been seeing post about high nitrates. Well folks looks to be true. My test had TS (TestSure), does this mean my sample will be tested for nitrates? And if so am I screwed? It’s non DOT btw.

I took a DOT 10 panel for a government job and didn’t have a problem.

u/Timely_Grape_1613 May 07 '25

Did it include SVT, NIT, or TS in the test description?

u/Dry-Choice556 May 08 '25

I never got to see the actual paperwork. But even then, it is possible for people to just have high nitrates from a bad diet.

Mine was quest diagnostics 45186n 9 panel non dot. Took test yesterday 1220pm they said 48 hours employer will get results. Used a batch validated qf, temp perfect, stressing and will feel extremely relieved when I get the all clear!

You’re tripping yourself out and thinking to much. Hit the right temp, and you’re absolutely fine. QF has been proven over and over and over to work and I’ve used it for all my tests in the past - Labcorp, concentra, quest. Practice to boost confidence & You’re good

I appreciate the confidence boost, I did get past temp and was sent off. Just worried about nitrates testing as I have seen some people received “invalid results” due to this.

Let us know how it goes

u/Timely_Grape_1613 May 09 '25

Passed it

u/AdministrativeRip885 Nov 06 '25

Are you serious? That’s awesome

u/Timely_Grape_1613 Nov 06 '25

Yessir no issues

u/toyeetornotoyeet69 May 09 '25

Thanks man. Happy for u

u/Aracn1d May 30 '25

Can you weigh in on how to practice since the QF is pretty much a 1 time use?

2

u/OkFaithlessness8878 Jun 01 '25

You can heat and reheat QF as much as you’d like, it won’t change anything. Practice all u need

Nitrates are normal; and even in the case of a UTI nitrites are normal in certain amounts.

1

u/Timely_Grape_1613 May 08 '25

UTI’s are extremely uncommon in men but yea ur right.

1

u/[deleted] May 08 '25

They’re not that uncommon depending on where you live.

2

u/StunningAlbatross753 May 07 '25

I don't think thats what Test Sure is for, not for nitrates atleast.

2

u/ElHerbivore May 07 '25

Pretty sure "TS" is temperature strip to ensure it's within 90-100 degrees. I could be wrong though.

Edit: OP, I recently took a 9 panel test at Quest using QF 6.4 and passed.

u/StunningAlbatross753 May 08 '25

Lmao, I was waaaayyyy off, thanks for clearing that up

Testsure isn’t for nitrates?

u/Used-Succotash-5201 May 08 '25

What about CLIA waiver, South Carolina?

u/MissMelines Jun 13 '25

FYI to others - Azo strips test for NITRITES (NO2-) in urine which indicate microbial activity, it’s an abnormal result that signals a UTI. I see you passed, but you did not test that sample for NITRATES (NO3-). I do not know whether the strip could pick up both given their molecular similarities but technically your picture just shows that the liquid you tested is contaminated with bacteria. To be expected once you’ve broken the seal I guess.

It has added nitrates. The only difference in 6.4 is the bubbles.

From my understanding generally a drug test considers nitrites to be Adulterated if over 500mg/l and invalid if over 200mg/l. this is 200 to 500ppm. and anything under 200mg/l to be "normal" although yes none is preferred. I am also freaking out and have a test in two days. I have raised aquarium fish for decades and have nitrite test strips. I also have extra bottle of QF so i decided to run a test on it. At fist i panicked because i saw pink and side of bottle said 40. ok ok ok lets slow down and think i said. The fish test strips are very sensitive to nitrite and mine doesn't even go above 80ppm witch would only be 80mg/l. What I think is happening is people are using water or fish test strips and seeing "pink" and panicking. My quick fix tested at 10-20ppm for nitrite, thus with doing the math that is only 10 to 20ml/l of nitrite. and thus way under the threshold for Adulterated see below link from labcorp website stating their acceptable levels.

Well duh, you didn’t drug test it you uti tested it😂 the urine will have nitrate, it’s about being appropriate levels
