The Creatinine Urine Test is a diagnostic procedure that measures the amount of creatinine present in the urine. Creatinine is a waste product produced by muscle metabolism. Normally, the kidneys filter out creatinine and other waste products from the blood, which are then excreted through urination. This test helps in evaluating the functioning of the kidneys and can be instrumental in diagnosing kidney-related conditions.

Purpose of the test
The primary purpose of the Creatinine Urine Test is to assess the functionality of the kidneys. By measuring the amount of creatinine in the urine, healthcare professionals can determine how effectively the kidneys are filtering out waste products from the bloodstream. This test is crucial for diagnosing or ruling out kidney diseases and other conditions that might affect the kidneys, such as muscle disorders.
Who Should Get Tested
This test is recommended for individuals who might be experiencing kidney problems. Since creatinine is a byproduct of muscle metabolism, any irregularities in its excretion can indicate issues with kidney function. The test is particularly useful for those showing symptoms of kidney disease or other conditions affecting the kidneys. It's also used to monitor the health of individuals with known kidney conditions.
Blood Test Preparation Guidelines
Time of day
It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.
Fasting
It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.
Stay hydrated
Drinking water prior to testing can help with sample collection.
Other factors
Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.
Medications and supplements:
Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.
Biotin supplements:
High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Preparing for Urinalysis Test
Buy container
Buy sterile, disposable urine containers from pharmacies.
You can also buy a container from a diagnostic centre but the price will be higher. Container is not included in the price of the tests.
Time of day
Ideally, collect the first urine in the morning after an 8-hour overnight rest or at least 4 hours after the last urination to prevent functional proteinuria.
Mid-stream Sample
Collect the urine mid-stream, not at the beginning or end of urination, to avoid contamination. The sample volume should be 20 to 100 milliliters, depending on the container's size.
Hygiene
Wash the area around the urethra with warm water, without using any cleaning or disinfecting products.
Fasting
Do not eat or drink for 12 hours before collecting the urine sample. If necessary, you can drink one glass of clean, unflavoured water during this time.
Physical activity
Avoid intense physical activity before providing a urine sample, as it can lead to an increase in protein and ketone levels in urine.
Menstrual period
Women should avoid providing a urine sample during the menstrual period or within two days of its completion, as this can affect the test results due to the presence of red blood cells and epithelial cells in the urine.
Sexual activity
Abstain from sexual activity before providing a urine sample.
Deliver sample
Take the sample(s) to the sampling point on the same day. Storage: Keep the samples at refrigerated temperature (+2...+8°C) until they are taken to the sampling point.
Interpreting Test Results
Creatinine levels in the urine can vary based on factors like age and muscle mass. Typically, normal urine creatinine values range from 955 to 2,936 mg per 24 hours for males and 601 to 1,689 mg per 24 hours for females. However, these values can differ across laboratories. Values outside the typical range might indicate conditions like kidney disease, kidney infections, kidney failure, or muscle disorders. It's essential to discuss the results with a healthcare provider for a comprehensive understanding and any necessary follow-up.
