5+Crt+pH-BUN = Urinalysis, right?

Just got the form for our test (it will be through Labcorp) and it had that (5+Crt+pH-BUN) written on it, and also some other indicators that it was a urinalysis (ie: a section to record temperature 90-100). But they said on an intro letter that they follow DOT standards (even though this is not a DOT job) and so I just wanted to run it by you pros and make absolute sure it was a urinalysis and nothing more, as I'm unfamiliar with how DOT conducts their tests.

Also, based on that equation above, still no problem with the vitamin/detox drink beforehand, correct FBR? From my time here I figure that is a 5 drug screen plus testing for Creatine and pH levels to make sure it is actual urine, so we should be good to go with our original plan.

Thanks in advance for the reassurance! :D

Are you sure it said BUN on it?

Sounds like a standard DOT test.Nothing special about them.I get them all the time.For DOT they test you for alcohol too which seems kind of idiotic.How many people would go get drunk a few hours before the test.

Yeah, 100%, just went and checked again. The equation is exactly as I typed, with the ending being pH-BUN. What does that mean? :wtf:

That's pretty much the only writing/type on the entire form, by the way. It is printed under a section, but I can't really tell WHAT section it is, just kind of randomaly printed in an empty box. Basically no other type or writing on the form other than that.

Found this.
So it appears its just done if you list a medical condition that might effect the outcome of the tests.

How is it used?
The BUN test is primarily used, along with the creatinine test, to evaluate kidney function under a wide range of circumstances and to monitor patients with acute or chronic kidney dysfunction or failure. It also may be used to evaluate a person’s general health status when ordered as part of a basic metabolic panel (BMP) or comprehensive metabolic panel (CMP).

When is it ordered?
BUN is part of both the BMP and CMP, groups of tests that are widely used:

when someone has non-specific complaints,
as part of a routine testing panel,
to check how the kidneys are functioning before starting to take certain drug therapies,
when an acutely ill person comes to the emergency room and/or is admitted to the hospital, or
during a hospital stay.

BUN is often ordered with creatinine:
when kidney problems are suspected,
at regular intervals to monitor kidney function in patients with chronic diseases such as diabetes, congestive heart failure, and myocardial infarction (heart attack),
at regular intervals to monitor kidney function and treatment in patients with known kidney disease,
prior to and during certain drug treatments to monitor kidney function, or
at regular intervals to monitor the effectiveness of dialysis.

Thanks, Blindman.

Came across this myself just now...

Blood Urea Nitrogen
A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine.

A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level. A low BUN level can occur normally in the second or third trimester of pregnancy.

Blood urea nitrogen to creatinine ratio (BUN

Just thinking out loud here... Reading about what BUN is (basically seeing if your kidneys are allowing a certain amount of urea or nitrogen out) I wonder if possibly it is used to see if any 'masking agent' or 'altering agent' is preventing certain substances (ie: drug indicators) from leaving your kidneys and entering your blood stream. Meaning, if the BUN test is showing that it is being prevented from leaving the kidneys correctly than maybe it is an idicator that the individual has something in their system controlling their kidneys from releasing levels of other/all things into their urine? *shrugs as he realizes he has no idea what he's talking about* Any credence/concern to that?

I also notice above in the article I quoted that it is tested in blood not urine (at least in that type of test) though the form we were given today sure makes it seem like this is a urinalysis only, and when I spoke to Labcorp about their hours they made it seem like it was urine only (ie: said it would only take 10-15mins and advised we are ready to give sample/urinate when we get here). Then again, they do do all types of tests, and they didn't have any information from myself or the form.

Ok, I'm simply rambling here, I'll stop. Curious as to what FBR has to say, as the BUN seemed to surprise him. *gulps*


I'm STILL freaking about this detox drink causing an invalid or 'masking agent detected' result, and therefore them failing her or asking her to come back in for a hair sample or something more detailed. Though I'm sure that's just my own paranoia, as FBR and others have reassured me time and time again that it won't.

*sighs* Can't wait til this is over, been obsessing about it WAY too long! And the poor girl is almost 4 weeks clean now anyhow, RIDICULOUS that she still has to go through all this crap! Damn drug tests!! :mad:

Are you concerned the Duz'z It detox drink could effect the BUN level part of the test, FBR?

I doubt the detox drinks will show an adulterated sample but I'm not much of a fan of any of the detox programs.If you need to be 100% sure then quickfix is the only way.If you've stopped smoking for a while then do the normal known to work things.Drink lots of fluid the day of the test,piss a few times before the test and take the midlle of your piss stream.

If this is a LabCorp DOT type test it is just a normal type piss test.I've done probably 20 over the last 8 years.Nothing special,thye don't watch you pee,they check the temp,it'll be a split specimen.
If you do fail it will be up to your employer whether you get to get tested again or not.The lab don't care but they don't do it for free.

If you've been clean for 4 weeks you'll be fine.I'm a big guy 6'2" 280 lbs and it takes me about 2 to 3 weeks to get clean when I've been smoking heavily.

Thanks for the adviec, Blindman, I appreciate it. It is for my wife, not me, but we were REALLY heavy users (super strong bud, multiple times a day, for many many years) prior to her stopping. It'll be about 28 or so days since she smoked when she goes in tomorrow morning. I'm just not confident enough to have her go in as is (even though she has passed a few home kits) as I figure we can explain a super-yellow urine sample or their concerns of it being altered or even restest, much moreso than we could explain away ANY amount of THC being found in her sample. With this job, if there is ANY thought of drug use, she's done, period. And people have told me that passing a home test is not a 100% guarantee you will pass the lab one. Likely, but not 100%, which is why I'm having her use the Duz'Z It Detox drink as well (posted more info about that in a few others threads).

I now have twice as much work to do because of blindman's guesses and inexperienced answers. Did the word "blood" escape blindman when you were looking up BUN? That is because the test is run on blood not urine. I am pretty sure Crt is not creatine clearance either which is usually abbreviated CrCl. This little string of codes almost describes a blood test and not a blood test for drugs. You very well may have a drug test but you might also have a blood test too. I would prepare for a urine test and that is that. If they told her that she has a urine test coming, she better get ready for it. Any chance she is getting a physical too? No, the Duzz it isn't going to affect BUN.

Blindman, just because you got clean in 3 weeks doesn't mean everyone else will too. The half-life of THC ranges from 0.8 days to 10 days depending on the person. Then there is smoking history to take into account.

If this is a preemplyment drug test.DOT never tests blood unless theres been an accident involved.And I'm pretty sure they wouldn't be concerned with the blood temp.My understanding of the BUN test is it is never done unless you have listed a medical condition that might effect the outcome of the urine test.

How did I know that you were going to read my post and not understand any of it? I never said they were going to test his blood for drugs, never, not once. I said he might have a blood test in addition to a urine drug test. Now stop it because your advice isn't the best.

Interesting. I'm rather confident that she is not getting a physical there tomorrow. The form we are required to take is titled "<State name> Drug Free Workplace Chain of Custody Form". Also, the info sent by the organization hiring her says (regarding the drug test):

"I understand that the ____ has adopted the drug testing program as mandated by the Department of Transportation (DOT)....

.....

.... I hereby concent to the taking of urine or other type of samples as approved by the DOT for purposes of the above drug testing program and to the test of such samples by <labatory and doctor's name>....."


And never mentions anything about a physical, or other blood test for non-drug reasons, or medical tests, etc... *shrugs* Doesn't mean absolutely not, but my gut (and the phone call with the lab this morning) made me really think it was a quick urinalysis, nothing more. Interesting to hear what you said about the string I listed though. Very.


I called the people at PassYourDrugTest.com (not that I trust them anywhere NEAR the level to which I trust and respect your advice) to explain her situation and ask if there was ANY chance to their knowledge of whether or not that syrup and the vitamin capsule she is instructed to eat tomorrow could cause a contaminated or invalid or 'masking agent' result. They told me no. When asked if they have EVER had it come up as a masking agent they said that if it ever happens or they learn how to test for it, they change the formula. And that no, the syrup I have has never had any problems.

Not sure if that answer made me feel better or worse. :o LOL! Anyhow - and I'm gonna sound like a broken record on repeat here - my heart of hearts tells me to use it because we'd rather have to answer to claims of the sample being dilluted or invalid or full of substances to the point of them thinking we were masking, than have to answer for a level of THC found in her urine. <-- As THAT would not be a question to be answered, it would be a curtain call.

So I think we're set with what we're doing. And the fact that YOU, FBR, haven't taken issue with this syrup, looked through all the ingredients, and still feel she'll be fine taking it, has REALLY made me feel reassured and cemented my decision. You told me last week that there is a chance (albeit it very slight) that she could pass a home kit the morning of and still fail at the lab. Any chance is too much in this case, so I think being 'better safe than sorry' with the Duz'Z It is the right call here.

I'll surely let you know how it goes.... and thanks once again for all of your help, man, I can't tell you how much it has meant to the two of us! :)

Well shit,now I've hady feelings hurt.I think I'll go smoke a bowl before I go postal.lol

Nothing we could do about it at this point anyhow, but if they pop a drug-based blood test on her tomorrow as well as the urine, is she good on the blood level at a 28-30day window with the detox kit we did (as if that kit likely had any affect! *laughs at himself and the $200 that is gone* :o)?

Blood detection is a much shorter window than urine. To make one thing clear, I am not a fan of this syrup and I didn't recommend it. I am just saying it will not hurt you to use it (unless you drink a lot of fluids with it) as it is mainly vitamins and fiber.

Absolutely, I'm sorry if I mistakingly implied otherwise. Your advise to me was NEVER to take this syrup or endorsing it as a good/useful product, or anything in that manner....

Your advise to me about it has been strictly in regards to whether or not it will cause a failed or dilluted or invalid or 'masking agent' result, which was my biggest fear about it (at her low toxin levels at this point I'm not too concerned about how effective it is, as she's so close anyhow)... and in that regard, you've made me feel much more assured that it will not cause one of those results.

Glad you cleared that up, and sorry if I made it seem otherwise, as I wouldn't want folks on this forum to think that you endorse that product or any like it. You don't, heck, you don't even really support the manner in which we've approached this test, as you've made it VERY clear the way to go is substitution, period. But it's been very kind of you to help us with what we have on our plate, as your knowledge is incredible, and has been a big relief for us.

For what it's worth....

Dug through her packet of info and came across a section about the testing It said that "Body Specimen" will be:

Urine will be used for the initial test for all drugs except alcohol. Blood will be used as the initial and confirmation test for alcohol...."


Interesting. It also listed the 5 drugs the pre-employment/DOT test would test for and what the levels were. Seemed rather standard, with THC being 50ng/mL Initial Cut-off and 15ng/mL for Confirmation cut-off.

By the way...

it was a standard and quick urinalysis, no blood or other samples taken.

Let us know how it turns out.
