I may have to have this on my body for about 6 hours. How long can urine be before it is no longer good for testing. I'm tired, I'm sorry if this is a repeated question. Thank-you!

get a bottle of quick fix 4.0 and it can last for a year if you keep it out of direct sunlight...... cost 20 to 35 $$$ plus shipping ..... has a temp strip on it so you know what the temp is .....

Thanks for your answer but I'm not buying another product. I'm subing someone else's and it will probably be abour 3 hours old before it will be tested. Will it still be OK to test?

Thanks Bobo, I have spent to much on detox products. Yes, I know, I'm dumb. The dilution method works just as well. In fact, I'm using that too and that is why the sub urine will be 3-4 hours before tested.

Thanks!

8 hours is safe. It could probably go a little longer than 8 hours is kind of the safe number often recommended on this site.

Midnight called Bogo Bobo, that was funny!

It was a type-o. My forensic drug testing custody and control form specifies a SAP 10-50 GC/MS. I understand that an EMIT is first applied. From a previous a posting or thread it is stated that a 50 NG/ML cutoff will be applied before it is sent for the most expensive test GC/MS. If one is tested with a level of 44 during the EMIT does the specimen go to the most expensive test the GC/MS?

What metabolite cutoff is used for an EMITT test before it goes to the most expensive GC/MS test.

Thank-you!

You posted this question 3 times, different levels in each post though. I don't plan on answering it 3 times.

If the cutoff is 50, the cutoff is 50. However, I wouldn't be confident giving a urine sample that had 42 or 44 ng/ml for several reason.

In fact you would never catch me handing over a sample that had 42 ng/ml ever.

First of all, Buzzby and a few others say the immunoassay is only a yes under 50 or a no, not under 50. I swear I have seen numbers from immunoassy but I could be wrong. That is out of the way.

What time of day is this 42 ng/ml urine being produced? If this was my first void I might be willing to hand over a sample from later on in the day but that would be my last resort. If you are that close, small changes in your fluid intake shortly before the test might affect the outcome. On a very unlikely tangent, your physical activity or food might have a chance to affect it with it being so close. The fluid changes would really worry me.

Now on a paranoid conspiracy theory, I wonder when they calibrate the machines how accurate and precise they have to be. I wonder if they are given any room for error either in your favor or against you. If so 42 or 44 is just a hair over 10% and that would scare me.

Also, do an advanced search using posts by me and the term 31 metabolites in quotes and read up something from last fall. Immunassay and GC/MS look for different metabolites. The important thing about GC/MS isn't that it is more expensive, it is more accurate and exacting in what it is looking for.

I took one of those in-house test from Walgreens that indicated a faint line but passing. So like a dummy I didn't dilute, sub, nothing. I thought i was fine. NOT, I failed. I got a 42 around 3:00 p.m. urine. You can refer to Let this be a lesson for background.

I thought I was going to get another chance to retest, in fact the H.R. person directed me to go to the same lab for a retest since I submitted research on particular PPI that cause false positives. Well I get to the lab for retest, no paperwork. Long story short the H.R. person changes her story and said the retest must be on the same urine specimen.

The lab person saw I was and asked me to call the MRO for my results and confirmation of specimen ID # on my copy of the lab sheet. She stated there have been mistakes in the past. I did and the MRO was out but the assistant MRO shared with me that the screening showed a 42, I believe she said Emmit. That is passing with an Emmit, why was a CG/MS conducted and she backed off quick and ask me to call later to speak with the MRO.

I later spoke with MRO and question him and as to why a CG/MS was run when the metabolite level was a 43 at the screening. He got real defensive and said the Emmit is only given to insure NO FALSE POSITIVES and everyone is given a 15 CG/MS. Which is B.S. because the MRO website says a 50 cut-off for Immunoassay (is that the same as an EMIT?). So he is lying and trying to cover up for the assistant.

Then I got call from the ESA who basically said that the same thing as the MRO and that the 10-50 GC/MS is just a code on the sheet and NOT a drug test name. All urine specimen are given a 15 GC/MS and mine was a 42, almost 3 times the 15 level. He said I can request a 2nd retest for $250.00 on the second bottle B re-test. I told him there is no bottle B, my specimen collection was Single collection. He said they split the single specimen in the lab. Which is another lie or if they did, they are not following lab collection procedures nor did I give a second sample or watch the collector split the samples with GLOVES. For all I know they could have contaminated my specimen, if it was my specimen. The collector later verified to me that there is a different collection procedure for a split and she has to conduct them. So if they did do that in the lab, they weren't suppose to.

I just wanted to re-confirm the testing steps of screening and then the CG/MS. This lab is ripping off this employer if they are running a 15 CG/MS on every urine specimen and running an EMMIT to only rule out false positives. What good is a negative in-house test when it is based on a 50 cut-off and the some labs are running CG/MS slightly under. OK, Thank-you
for the info. I hope Bogo did take offense, it really was a typo!

Sec

The lab person didn't change her story, you always have the opportunity to have the same specimen sent to a second lab for a re-test. You just misunderstood.

You are again mistaken. Your GC/MS showed a 42ng/mL. That is for one particular metabolite. There are 31 different metabolites in THC. The EMIT or Immunoassay, only gives a yes or no for the entire array added together of all 31 metabolites. the GC/MS gives actual quantities for one metabolite. So, in reality, the EMIT was positive, the GC/MS was more detailed.

Again, you misunderstood. They are not the same tests. They don't give the same results. One is a "yes it is there", "No, it isn't there" and the other is an actual nanogram per milliliter level.
Who is this? It isn't a lie. They don't usually use all of the specimen for the test. Usually only about 15 mL is needed. If you gave one vial of 30 mL, they would have about 15 mL available to run a re-test. That really wouldn't do you any good, because it is from the same void. again, you misunderstood. yes, the collector collects a split specimen. However; there can be two separate tests run on the same vial in a single collection as well if the donor insists. You will have to pay for it though. Since you and I both know any re-test of the same void will show the same results, if you insisted on a re-test of the same void, you would be wasting your money.

you got that backwards. Of course they schedule a GC/MS on every test. However; not every test needs a confirmation (which is what a GC/MS acutally is. It confirms with quantative levels of what the EMIT actually found. That isn't nice.

Naaaa no big deal for me on the name..... what I just was saying use quick fix which is subbing
synthetic urine is quick-fix 4.0...if you used it you would have passed

I meant to write "I hope Bogo does NOT take offense". It was another typo. Given the long write-up please understand.

Sec3, your explanation is a little confusing regarding the EMMIT, my understanding (from this forum) and what is stated in the booklets of the in-house test kits the cutoff for the Immunoassay is 50. The MRO assistant said it was a 42 when asked what the cutoff was of the 1st screening NOT the CG/MS. Maybe she does NOT know what she is talking about or misunderstood me. I got a negative on the in-house test before lab test. Oh by the way I did conduct 2 different test kits yesterday WITHOUT dilution and both were NEGATIVE. One with a faint (which is the original test kit tested before lab which was a faint line) and a strong negative line on the other test kit. I'm not a chronic user. So I'm able to pass after one week to the day on an in-house test kit. So you can imagine after 30 days.

The MRO stated that the EMIT is only run to check false positive, NOT what you stated i.e. to check if it is there "yes" or "no" result. I imagine that the cut-off of 50 for marijuana determines a yes or no. I didn't misunderstand the MRO statement. My understanding that an EMIT is run to see if the more expensive CG/MS is required for verification. So why would they run an EMIT for a false positive at this point?

In the case of a false positive, the lab needs to know the prescription drug and run another verification. The lab did not know about my prescription drug until AFTER the positive result was given.

I signed for and witnessed a single specimen collection. The collector stated a split or single specimen are taken at collection time only because there are different procedures for each. I did not misunderstand the collector. A split B test is what's required, a split specimen collection procedure was NOT conducted by the collector nor witnessed by me. I did NOT witness my urine put into two vials and tagged as mine. Mistakes have happen at Labs and I would feel more comfortable to have seen my urine specimen collected in two different vials by the collector NOT at the LAB. Besides I can't afford a split test nor will I authorize for one unless the specimen collected was conducted per split collection procedure.

Thank-you all for your views and feedback!
