What is Creatinine?
Serum creatinine is a substance that our bodies make as a result of a chemical called creatine phosphate, which is found in our muscles. It is produced consistently at a steady rate, meaning it doesn't change much over time. The amount of serum creatinine we have in our blood is influenced by the amount of muscle we have - so people with more muscle tend to have higher levels. Additionally, men usually have higher levels of serum creatinine compared to women, while pregnant women tend to have lower levels.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors measure the level of creatinine in your body. Before the test, it is important to follow some pretest preparations. This includes avoiding certain medications that can affect the results, fasting for a few hours, and drinking plenty of water. In the lab, a small sample of blood is taken from your arm using a needle. This blood is then analyzed to measure the concentration of creatinine, which is a waste product produced by our muscles.
Is creatinine 8.2 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 8.2 in male across different ages
| Age Group | Is Creatinne of 8.2 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |

| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 8.2 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 8.2 is considered abnormal.
What could cause a creatinine level of 8.2?
- Acute kidney injury: Sudden loss of kidney function due to various causes such as dehydration, kidney infections, or certain medications.
- Chronic kidney disease: Progressive and irreversible damage to the kidneys over a long period, often caused by conditions like diabetes or high blood pressure.
- Urinary tract obstruction: Blockage in the urinary tract that prevents normal urine flow, leading to increased creatinine levels.
- Nephrotic syndrome: Kidney disorder characterized by increased leakage of protein in urine, causing damage to the kidneys.
- Glomerulonephritis: Inflammation of the kidney's filtering units (glomeruli) that can impair kidney function.
- Rhabdomyolysis: Breakdown of muscle tissue, releasing toxic substances into the bloodstream and affecting kidney function.
- Hemolytic uremic syndrome: A rare condition where red blood cells are destroyed and can clog the kidneys, leading to kidney failure.
- Polycystic kidney disease: Inherited condition causing the formation of cysts in the kidneys, leading to impaired kidney function.
- Tubulointerstitial nephritis: Inflammation of the tubules and interstitium in the kidneys, often caused by medications or infections.
- Renal artery stenosis: Narrowing of the arteries that supply blood to the kidneys, resulting in reduced kidney function.
What other tests should be done if creatinine level is 8.2?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps to assess the balance of electrolytes in the body, such as sodium, potassium, and chloride. An elevated creatinine level can indicate kidney dysfunction, and the Serum Electrolytes test can provide valuable information about the kidney's ability to regulate electrolyte levels. Monitoring electrolyte imbalances is crucial as they can lead to serious complications, including cardiac arrhythmias and neurological disturbances.
Blood Urea
The Blood Urea test is important because it measures the amount of urea nitrogen in the blood, which helps assess kidney function. In the case of a creatinine level of 8.2 mg/dl, a Blood Urea test is crucial as it can provide additional information about kidney health, such as indicating the presence of urea build-up due to impaired kidney function or other underlying conditions. This test can help diagnose and monitor kidney disease and guide treatment decisions.
Estimated GFR
The estimated glomerular filtration rate (eGFR) test is important because it helps assess kidney function by estimating the amount of blood filtered by the kidneys per minute. A creatinine level of 8.2 mg/dl indicates severe kidney impairment, but eGFR provides a more accurate assessment of the extent of kidney damage and helps guide treatment decisions, such as dialysis or transplantation.
HBA1C
The HBA1C test is important in this case as it measures the average blood sugar levels over the past three months, providing valuable information about long-term glucose control. It helps in evaluating the risk and management of diabetes, which can have a significant impact on kidney function. Monitoring HBA1C levels can aid in preventing further kidney damage and managing the overall health of the patient.
LDH
The LDH test is important in this case because it helps evaluate kidney function and assess the severity of kidney damage. LDH levels can be elevated in conditions such as acute kidney injury or chronic kidney disease, providing valuable information for determining appropriate treatment strategies. Monitoring LDH levels alongside creatinine levels can help healthcare professionals better understand the extent of kidney impairment and guide patient management decisions.
Random Sugar
The Random Sugar test is important because it helps evaluate blood glucose levels at any given time, which is crucial in detecting and diagnosing diabetes. In this case, a high creatinine level of 8.2 mg/dl indicates potential kidney dysfunction, which can be a complication of uncontrolled diabetes. Therefore, the Random Sugar test can provide valuable information for managing diabetes and monitoring kidney health.
What is the relation between creatinine and kidney function?
Creatinine, a chemical generated within the body consistently, undergoes complete elimination by the kidney via urine filtration. Whenever the kidney's performance is hindered by any underlying factors, there is a surge in creatinine levels. Consequently, creatinine emerges as a highly valuable means to evaluate the efficiency of renal function.
Why do doctors ask for GFR if my creatinine level is 8.2?
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.
