The Creatinine Blood Test measures creatinine levels in the blood to assess kidney function. It helps detect kidney disease and monitor overall kidney health. Costs vary by location and lab type. Early detection through this test ensures timely treatment for kidney issues.
What is the Creatinine Blood Test?
The Creatinine Blood Test measures the concentration of creatinine in the blood. Creatinine is produced from the breakdown of creatine, a substance used by muscles to produce energy. Normally, the kidneys filter creatinine out of the blood and excrete it through urine. It is frequently employed to assess
- Kidney health,
- Diagnose kidney disorders,
- Assess the effectiveness of treatment and
- Identify early indications of kidney damage or dysfunction.
Assessing creatinine concentration in the blood -
- Indicative of kidney function
- Included in regular blood tests to evaluate kidney health
- A diagnostic tool for kidney diseases
- Monitoring the effectiveness of treatment
- Early identification of kidney damage.
Other names: serum creatinine, blood creatinine, kidney function, urine creatinine, renal function
How Should I Prepare for the Creatinine Blood Test?
Your healthcare provider might advise you to pause certain medications temporarily as they could influence the test results. These medications include:
- Cimetidine, famotidine, and ranitidine
- Specific antibiotics, for example, cefoxitin and trimethoprim
- Make sure to inform your provider about all the medications you are currently taking.

How Do I Understand My Creatinine Blood Test Results?
Serum creatinine test results are reported in milligrams per deciliter (mg/dL). Normal creatinine levels depend on factors like sex, age, and muscle mass. Generally:
- Males: 0.7 - 1.3 mg/dL
- Females: 0.6 - 1.1 mg/dL
Elevated serum creatinine levels may indicate impaired kidney function. To determine the cause, your doctor will compare these results with other tests, such as blood urea nitrogen (BUN). Additional tests may be conducted if creatinine levels are high.
Serum creatinine level also helps estimate the eGFR (estimated glomerular filtration rate), which assesses how effectively the kidneys filter waste from the blood.
Why is the Creatinine Blood Test Done?
This test is primarily performed to evaluate kidney function. Your kidneys are responsible for filtering waste, and creatinine is one of the main substances they filter.
- Monitor kidney health: If you have conditions like high blood pressure or diabetes, this test helps track kidney function.
- Diagnose kidney diseases: Elevated creatinine levels can signal kidney damage or disease.
- Monitor medications: Some medications can impact kidney function, and this test helps monitor their effects.
When is the Creatinine Blood Test Needed?
Your doctor may recommend this test if you exhibit symptoms of kidney problems or have certain risk factors.
- Symptoms of kidney disease: Swelling in the legs, fatigue, changes in urination, or high blood pressure.
- Chronic conditions: Diabetes or high blood pressure can increase the risk of kidney damage.
- Medication monitoring: If you're on medications that affect the kidneys, such as certain antibiotics or blood pressure medications.

Get Second OpinionWho Should Take the Creatinine Blood Test?
The test is important for people who are at risk of kidney damage or who already have conditions affecting kidney function.
- People with diabetes or hypertension: These conditions increase the risk of kidney disease.
- Those on medications affecting kidneys: For example, some pain relievers or chemotherapy drugs.
- Individuals with a family history of kidney disease: Genetics can play a role in kidney health.
- Elderly individuals: Kidney function naturally declines with age.
What Type of Sample is Collected for the Creatinine Blood Test and How?
For the Creatinine Blood Test, a blood sample is required. The process is straightforward:
- Sample collection: A healthcare provider will draw blood from a vein in your arm using a needle.
- Duration: The blood draw usually takes just a few minutes.
Once the blood is drawn, it is sent to a laboratory for analysis. Results are typically available within 12 to 24 hours.
Are There Other Ways to Collect the Sample for the Creatinine Blood Test?
Currently, the standard method for testing creatinine levels is through a blood sample. There are no widely used alternative methods for this specific test, though:
- In some cases, a urine test may be performed alongside the blood test for more comprehensive kidney function analysis (e.g., urine creatinine clearance test).
How is the Creatinine Blood Test Performed?
The process for the Creatinine Blood Test is simple and involves the following steps:
- Preparation: The healthcare provider cleans the skin around the vein where the needle will be inserted.
- Blood Draw: A needle is inserted into a vein in your arm to collect the blood sample.
- Lab Analysis: The sample is sent to a lab, where the creatinine levels are measured.
- Result Review: The doctor will review the results and discuss them with you.

How Long Does the Creatinine Blood Test Take?
- Blood Draw: The actual blood collection takes just a few minutes.
- Results: You can expect the results within 12 to 24 hours, depending on the lab's processing time.
Most labs can send results directly to you via email or text, or you may receive a printed report during your next doctor's visit.
When Will I Get My Creatinine Blood Test Results?
Results from the Creatinine Blood Test are usually available within 12 to 24 hours. You will typically receive the report:
- Electronically: Through email or SMS.

Frequently Asked Questions
The normal range of creatinine in the blood for men is between 0.9 and 1.3 mg/dL, and for women, it is between 0.6 and 1.1 mg/dL.
High levels of creatinine indicate that the kidneys are not functioning properly.
Low levels of creatinine indicate that the body is not producing enough creatinine.
If the creatinine level is higher than 1.2 for women and higher than 1.4 for men, it indicates kidney failure.
A creatinine blood test does not require any special preparation; one can eat and drink normally beforehand.
A doctor will order a creatinine blood test if the patient shows signs of high blood pressure, diabetes, thyroid issues, or a blocked urinary tract, etc., which can impair kidney functionality.
