What is Creatinine?
Serum creatinine is a substance that is found in our blood and gives us important information about our muscle health. It is produced in our body as a result of a chemical called creatine phosphate, which is found in our muscles. This means that the more muscle we have, the more serum creatinine we will produce. Interestingly, our body tends to produce serum creatinine at a steady rate, so it can be a helpful indicator for doctors to measure how well our kidneys are functioning. Since muscle mass differs between individuals, it's natural that the amount of serum creatinine in our blood can vary too. In general, men tend to have higher levels of serum creatinine compared to women because they usually have more muscle mass. Moreover, serum creatinine levels can also change during pregnancy. Women who are expecting may have lower levels of serum creatinine due to the changes happening in their bodies to support the baby's development. So, by measuring serum creatinine, doctors can gain valuable insights about our muscle health and kidney function.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors measure how well our kidneys are working. Before the test, it's important to let the doctor know about any medications we are taking, as some can affect the results. On the day of the test, a nurse will draw a small amount of blood from a vein in our arm using a tiny needle. They will then send the blood sample to the lab, where scientists will use special machines to measure the amount of creatinine in the blood. This information will give the doctor an idea of how well our kidneys are functioning.
What does a creatinine of 4.7 mg/dl mean in men?
The normal range for creatinine in women is between 0.73 and 1.18. If your creatinine level is 4.7 mg/dL, it is considered severe. It is highly recommended that you go to the hospital right away. You may need dialysis to help your kidneys function properly. The doctors might also need to do a small test on your kidney to find out what is causing the problem. If it is determined to be due to your immune system, you may need medication to suppress it. You will also need to receive fluids through an IV. Other possible causes of high creatinine levels could be kidney damage from diabetes or high blood pressure.3,4
Is creatinine 4.7 dangerous?
A creatinine of may be dangerous depending on your gender and age. The tables below highlight the likelihood of a creatinine of being dangerous for different age groups in both men and women. We provide the following tables, based on the estimated GFR corresponding to the value of creatinine.
Table of danger posed by Creatinine 4.7 in male across different ages
| Age Group | Is Creatinne of 4.7 dangerous? |
|---|---|
| 25yrs - 28 yrs | very high - dangerous, Consult a doctor immediately |
| 28yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |

What is the normal range and is a creatinine of 4.7 mg/dl normal?
The normal range for creatinine in men is 0.73 to 1.18 mg/dl, and in women it is 0.55 to 1.02 mg/dl2. Based on these ranges, a creatinine level of 4.7 is considered abnormal.
What could cause a creatinine level of 4.7?
- Chronic kidney disease: A common cause of elevated creatinine levels is chronic kidney disease, where the kidneys are not functioning properly, leading to an accumulation of creatinine in the blood.
- Acute kidney injury: Sudden kidney damage or injury can result in elevated creatinine levels. This can be caused by severe infections, dehydration, medications, or kidney obstruction.
- Dehydration: Insufficient fluid intake or excessive fluid loss can lead to decreased kidney function and increased creatinine levels.
- Urinary tract obstruction: Blockage in the urinary tract, such as kidney stones or tumors, can hinder the normal flow of urine, leading to elevated creatinine levels.
- Urinary tract infection: Infections in the urinary tract can cause inflammation and damage to the kidneys, resulting in elevated creatinine levels.
- Heart failure: Impaired heart function can lead to poor blood flow to the kidneys, causing kidney damage and elevated creatinine levels.
- Liver disease: Liver dysfunction can affect the breakdown and elimination of creatinine, leading to its accumulation in the blood.
- Muscle disorders: Certain muscle disorders, such as rhabdomyolysis, can cause muscle breakdown, releasing creatinine into the bloodstream and raising its levels.
- Certain medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), certain antibiotics, and chemotherapy drugs, can affect kidney function and elevate creatinine levels.
- Severe infections: Serious infections, like sepsis, can cause damage to multiple organs, including the kidneys, leading to elevated creatinine levels.
What other tests should be done if creatinine level is 4.7?
Serum Electrolytes
The Serum Electrolytes test is important in this case as it helps assess the levels of essential minerals like sodium, potassium, and bicarbonate, which can be affected by kidney dysfunction. Abnormal electrolyte levels can further impact kidney function and overall health, requiring appropriate management. Monitoring these electrolyte levels is crucial in guiding treatment decisions and ensuring optimal kidney function.
Blood Urea
The blood urea test is important because it measures the levels of urea nitrogen in the blood, which is a waste product produced by the liver. Elevated levels of blood urea indicate impaired kidney function, which helps confirm the diagnosis of kidney disease or dysfunction in cases of high creatinine levels. Therefore, the blood urea test is crucial in assessing kidney health and determining appropriate treatment options.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important because it provides an estimate of how well the kidneys are functioning. In the case of a creatinine level of 4.7 mg/dl, the Estimated GFR test can help determine the stage of kidney disease and guide further treatment decisions. It is a key tool in monitoring kidney function and identifying any potential kidney damage or disease progression.
HBA1C
The HbA1c test is important because it measures the average blood sugar levels over the past 2-3 months, providing valuable information about long-term blood sugar control. In individuals with a creatinine of 4.7 mg/dl, the HbA1c test can help assess the risk and management of diabetes, as high levels may indicate poor glycemic control and the need for intervention. Monitoring HbA1c levels is crucial for the prevention and management of complications associated with diabetes.
LDH
The LDH (lactate dehydrogenase) test is important in this case as it helps in evaluating kidney function and diagnosing renal disorders. LDH levels can be elevated in conditions such as acute kidney injury or chronic kidney disease, indicating possible kidney damage or impaired renal function. Monitoring LDH levels alongside creatinine can provide valuable information for the diagnosis and management of kidney-related conditions.
Random Sugar
The Random Sugar test is important in this case because it can help determine if the elevated creatinine level is due to diabetes-related kidney damage. High blood sugar levels can lead to kidney damage, resulting in elevated creatinine levels. Conducting a Random Sugar test can reveal if diabetes is contributing to the high creatinine level, allowing for appropriate management and treatment.
What is the relation between creatinine and kidney function?
Creatinine, a chemical synthesized by the body in a consistent manner, undergoes complete elimination via the kidney during urinary filtration. When the kidney's operation is compromised, regardless of the cause, creatinine levels experience an increase. Hence, the measurement of creatinine serves as a highly valuable means to assess kidney functionality.
Why do doctors ask for GFR if my creatinine level is 4.7?
Glomerular Filtration Rate or GFR is the rate at which a given volume of blood is cleared of any substance every unit of time. This basically is a measure of the filtration capacity of the kidney. Even a small reduction in GFR can have consequences in patients who already have comorbidities. The GFR is calculated from the level of creatinine in the blood using a variety of equations like the MDRD equation given as follows : GFR (mL/min/1.73 m2) = 175 × (Scr)-1.154 × (Age)-0.203 × (0.742 if female) × (1.212 if African American). Using this formula the value of GFR can be calculated just by knowing the level of creatinine in the blood.
