Can be a result of short-term water loading (flushing) in an attempt to dilute any drug below testing cut-off concentrations. <2.0 mg/dL. Abnormally dilute: Specimen showing an excessively low creatinine value. May be an indication that the specimen is not consistent with normal human urine.
What causes low creatinine levels in urine drug test?
In conclusion, low urine creatinine values may indicate that an individual attempted to beat the drug test by drinking excessive fluid in an effort to flush the drugs from his system. When low creatinine concentrations are observed, it should be a concern for the agency performing the urine collection.
Is low creatinine good or bad?
Creatinine levels vary from person to person depending on factors such as body size, age, or gender, so there is no standard or ‘normal’ level. Low creatinine levels could indicate a problem with the muscles or liver but may be due to something less serious, such as reduced muscle mass in older adults, or pregnancy.
Does creatinine test positive for drugs?
Urine samples used in drug-abuse testing should be tested for creatinine; if creatinine is less than 4.0 mmol/L, negative results for drugs may not be valid.

What is a normal creatinine?
Results of the creatinine blood test are measured in milligrams per deciliter or micromoles per liter. The normal range for creatinine in the blood may be 0.84 to 1.21 milligrams per deciliter (74.3 to 107 micromoles per liter), although this can vary from lab to lab, between men and women, and by age.
What medications cause low creatinine levels?
The antibiotic trimethoprim-sulfamethoxazole and the H2-blocker cimetidine are 2 commonly used drugs that decrease the secretion of creatinine. This can result in a self-limited and reversible increase in the serum creatinine level of as much as 0.4 to 0.5 mg/dL (depending on baseline serum creatinine level).
What affects the creatinine level in a drug alcohol urine test?
Greater than normal intake of water will increase the urine water content (lowering the creatinine level) consequently diluting the amount of drug in urine. Conversely, a limited intake of water can lead to an abnormally concentrated urine specimen (as occurs with dehydration) resulting in elevated creatinine levels.
What does creatinine urine mean?
Creatinine is a normal waste product that the body produces every day during muscle movements and when digesting meat. Healthy kidneys remove creatinine from the blood, and it leaves the body in urine. High levels of creatinine in the urine can indicate diabetes, high muscle tone, or problems with the kidneys.
What does dilute creatinine mean?
A dilute urine sample means that the creatinine level is equal to or below 20mg/dl. This also occurs normally in the absence of kidney disease. The creatinine levels can change daily, but most people will have a “normal” value range for themselves most of the time.
