18 Αυγ 2023 · When we find abnormally low levels of creatinine in a client’s urine, that suggests that the sample may have been tampered with, affecting the test results for other substances. For these reasons, our reference lab compares the concentration of creatinine in each urine sample to typical ranges.

Urinary creatinine concentrations of less than 20 mg/dL are considered dilute, whereas concentrations of less than 5 mg/dL are inconsistent with human urine. 10 Urinary nitrite levels should be less than 500 μg/mL. 16 If adulteration is suspected or results fall outside these ranges, another specimen should be collected under direct, observed ...
5 Απρ 2024 · Any individual required to take a urine drug test who exhibits low urine creatinine levels may be suspected of urine tampering. A person with low urine creatinine levels who hasn’t tried to dilute their urine should consult with their physician to check out other potential causes of low creatinine.
18 Μαρ 2017 · Adulteration or dilution of the urine specimen should be suspected if the pH is less than 3 or greater than 11 or the specific gravity is less than 1.002 or greater than 1.030. 18 Urinary creatinine concentrations less than 20 mg/dL are indicative of dilute urine, whereas those less than 5 mg/dL combined with a specific gravity of less than 1. ...
“normal” urine creatinine level (say 130 mg/dL or above) on some days, it could be argued that exceedingly low creatinine levels (less than 20 mg/dL) at other times are not due to any type of disease process or physiological malady. In other words, if.
20 Σεπ 2016 · Introduction. Urine drug screening/testing is a commonly performed activity in various populations and settings (1–5). The frequency at which some populations are drug tested may be higher than others; e.g., drug treatment and rehabilitation center confined patients vs. a tenured university professor.
Therefore, if an individual is able to produce a “normal” urine creatinine level on some days, it could be argued that exceedingly low creatinine levels (less than 20 mg/dL) are not due to any type of disease process, physiological malady or medications.
