Creatinine is a metabolic by-product of muscle metabolism, and normally appears in urine in relatively constant quantities over a 24 hour period with “normal” liquid intake. Therefore, urine creatinine can be used as an indicator of urine water content or as a marker identifying a specimen as urine.
Do drug tests check for creatinine?
The most common form of specimen tampering is sample dilution. Creatinine testing is a specimen validity issue! EVERY urine sample collected for drug detection should be tested for creatinine!
Why is creatinine tested in drug test?
Creatinine is a by-product of muscle metabolism that is excreted in the urine. Its measurement is routinely used clinically to evaluate kidney function. Additionally, urinary creati- nine determination is an important parameter for evaluating the validity of a urine specimen for drugs of abuse detection.
What does creatinine mean in urine?
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 low creatinine in your urine mean?
Low creatinine clearance levels can mean you have chronic kidney disease or serious kidney damage. Kidney damage can be from conditions such as a life-threatening infection, shock, cancer, low blood flow to the kidneys, or urinary tract blockage.
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 causes urine creatinine to be high?
Generally, a high serum creatinine level means that your kidneys aren’t working well. Your creatinine level may temporarily increase if you’re dehydrated, have a low blood volume, eat a large amount of meat or take certain medications. The dietary supplement creatine can have the same effect.
What is normal creatinine urine level?
Urine creatinine (24-hour urine collection) values can range from 500 to 2000 mg/day (4,420 to 17,680 mmol/day). Results depend on your age and amount of lean body mass. Another way of expressing the normal range for test results is: 14 to 26 mg per kg of body mass per day for men (123.8 to 229.8 µmol/kg/day)
What is normal creatinine levels in urine drug test?
Normal urine creatinine values generally range from 955 to 2,936 milligrams (mg) per 24 hours for males, and 601 to 1,689 mg per 24 hours for females, according to the Mayo Clinic. Creatinine values that fall outside the normal range may be an indication of: kidney disease.
What drugs can cause abnormally elevated creatinine levels?
Symptoms that can accompany high creatinine
- antibiotics, such as aminoglycosides, rifampin, and vancomycin.
- cardiovascular drugs, such as ACE inhibitors and statins.
- chemotherapy drugs.
- proton pump inhibitors.

What are the symptoms when creatinine is high?
What are the symptoms of high creatinine levels?
- Chest Pain.
- Muscle Cramps.
- Changes in urination frequency and appearance.
- High blood pressure.
- Swelling or fluid retention.
What food should be avoided if creatinine is high?
Reduce your protein intake
People following diets very high in red meat or other protein sources, including dairy products, may have higher creatinine levels than people who eat fewer of those foods. If you eat lots of red meat, switch to more vegetable-based dishes. Try swapping out beef burgers for: vegetable patties.
What is the first sign of kidney problems?
Signs and symptoms of acute kidney failure may include: Decreased urine output, although occasionally urine output remains normal. Fluid retention, causing swelling in your legs, ankles or feet. Shortness of breath.
Is low creatinine in urine 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.
What is the creatinine level for kidney failure?
Creatinine levels in the blood can vary depending on age, race and body size. A creatinine level of greater than 1.2 for women and greater than 1.4 for men may be an early sign that the kidneys are not working properly. As kidney disease progresses, the level of creatinine in the blood rises.
