    I got picked for a random in my drug testing consortium. Long story short, when I went to pee I didn't have enough to fill the split sample vials. The tester dumped it and said I had to work up another sample, and sent me to the lobby to drink some water. After drinking some water and waiting, she called me back and I provided the sample.

    I get me test results by email today and it says "Negative (diluted sample)". Can the diluted sample cause me issues?

    I forgot to add, I think that means that your urine had a higher water content than normal, its still reported to clearinghouse as a negative result.

    No expert. But I suspect that is due to them having to dilute it. In order to have enough for the test.

    Part 40 goes into detail about this process. You are good, but you should pay close attention to those creatinine levels. Most likely this is what got you. NOBODY is allowed to mix anything in those split samples. In fact, the person that does your drug screen is supposed to IN YOUR PRESENCE seal them up. The lab can't test any samples not sealed.

    Just to be clear, here is what the reg says.

    I'm placing this in a spoiler box to save some space. Your answer is in 40.97 (a)(1)

    § 40.97 What do laboratories report and how do they report it?
    (a) As a laboratory, you must report the results for each primary specimen. The result of a primary specimen will fall into one of the following three categories. However, as a laboratory, you must report the actual results (and not the categories):

    (1) Category 1: Negative Results. As a laboratory, when you find a specimen to be negative, you must report the test result as being one of the following, as appropriate:

    (i) Negative, or

    (ii) Negative-dilute, with numerical values for creatinine and specific gravity.

    (2) Category 2: Non-negative Results. As a laboratory, when you find a specimen to be non-negative, you must report the test result as being one or more of the following, as appropriate:

    (i) Positive, with drug(s)/metabolite(s) noted, with numerical values for the drug(s) or drug metabolite(s).

    (ii) Positive-dilute, with drug(s)/metabolite(s) noted, with numerical values for the drug(s) or drug metabolite(s) and with numerical values for creatinine and specific gravity;

    (iii) Adulterated, with adulterant(s) noted, with confirmatory test values (when applicable), and with remark(s);

    (iv) Substituted, with confirmatory test values for creatinine and specific gravity; or

    (v) Invalid result, with remark(s). Laboratories will report actual values for pH results.

    (3) Category 3: Rejected for Testing. As a laboratory, when you reject a specimen for testing, you must report the result as being Rejected for Testing, with remark(s).

    (b) As a laboratory, you must report laboratory results directly, and only, to the MRO at his or her place of business. You must not report results to or through the DER or a service agent (e.g., C/TPA).

    (1) Negative results: You must fax, courier, mail, or electronically transmit a legible image or copy of the fully-completed Copy 1 of the CCF which has been signed by the certifying scientist, or you may provide the laboratory results report electronically (i.e., computer data file).

    (i) If you elect to provide the laboratory results report, you must include the following elements, as a minimum, in the report format:

    (A) Laboratory name and address;

    (B) Employer's name (you may include I.D. or account number);

    (C) Medical review officer's name;

    (D) Specimen I.D. number;

    (E) Donor's SSN or employee I.D. number, if provided;

    (F) Reason for test, if provided;

    (G) Collector's name and telephone number;

    (H) Date of the collection;

    (I) Date received at the laboratory;

    (J) Date certifying scientist released the results;

    (K) Certifying scientist's name;

    (L) Results (e.g., positive, adulterated) as listed in paragraph (a) of this section; and

    (M) Remarks section, with an explanation of any situation in which a correctable flaw has been corrected.

    (ii) You may release the laboratory results report only after review and approval by the certifying scientist. It must reflect the same test result information as contained on the CCF signed by the certifying scientist. The information contained in the laboratory results report may not contain information that does not appear on the CCF.

    (iii) The results report may be transmitted through any means that ensures accuracy and confidentiality. You, as the laboratory, together with the MRO, must ensure that the information is adequately protected from unauthorized access or release, both during transmission and in storage.

    (2) Non-negative and Rejected for Testing results: You must fax, courier, mail, or electronically transmit a legible image or copy of the fully-completed Copy 1 of the CCF that has been signed by the certifying scientist. In addition, you may provide the electronic laboratory results report following the format and procedures set forth in paragraphs (b)(1)(i) and (ii) of this section.

    (c) In transmitting laboratory results to the MRO, you, as the laboratory, together with the MRO, must ensure that the information is adequately protected from unauthorized access or release, both during transmission and in storage. If the results are provided by fax, the fax connection must have a fixed telephone number accessible only to authorized individuals.

    (d) You must transmit test results to the MRO in a timely manner, preferably the same day that review by the certifying scientist is completed.

    (e)

    (1) You must provide quantitative values for confirmed positive drug test results to the MRO.

    (2) You must provide the numerical values that support the adulterated (when applicable) or substituted result, without a request from the MRO.

    (3) You must also provide to the MRO numerical values for creatinine and specific gravity for the negative-dilute test result, without a request from the MRO.

    (f) You must provide quantitative values for confirmed opiate results for morphine or codeine at 15,000 ng/mL or above, even if the MRO has not requested quantitative values for the test result.

    No worries.
    I’ve gotten the same notation before. I was home doing yard work in the Florida heat all week drinking gallons of water every day. Went and got tested for a random and that was that..didn’t hear anything else about it.

    Here’s a little information on the topic.

    That's what I think also, and I've sure it is due to me drinking so much water in the lobby to try to work up enough of a sample.

    I guess what concerned me is I heard a old truck stop story about a guy that did drugs and thought that if he drank enough water right before the test, he would pee clean. As the story went, he ended up having such a high water content in his urine that they treated it as a positive. Now I don't put too much faith in truck stop stories, but just wanted to make sure.

    The longer version of the story is that I went in thinking I had enough urine in me for the test, I wasn't really having to "go", but I thought I was good. It has been awhile since I had a test, and I had forgotten how much urine they need for the split sample (it's a lot). When I attempted to give my sample the first time, I was a good 1/8" from the minimum line on the cup. The lady tried to make two samples out of what I had, but it wasn't enough. I hoped she would keep what she had and all I would have to do is add a little to it, but she said that was against the rules so she dumped it. My heart kind of sunk, because I knew I would have to work up a whole new sample.

    She sent me to the lobby with a drinking cup, with instructions to drink up to 3 cups of water and wait about 30 minutes. I was ready to get out of there so I downed the 3 cups and waited. I'm sure the 3 cups of water is what diluted it, but there was no trying to hide anything, I was just trying to work up enough pee in a short amount of time so I could get on with my day.

    I've never done any drugs my entire life that would result in a positive test.

    No no no no no!!!!! There has been no drug use charge. You really need to research what creatinine is.

    I HIGHLY recommend that you see a doctor! High creatinine levels can be a sign of kidney problems. Unless of course, you are taking a Creatine supplement.
