What is Creatinine?
Serum creatinine is a substance that our bodies naturally produce as a result of a chemical called creatine phosphate found in our muscles. It is like a leftover product that our body creates when it uses energy. The interesting thing about serum creatinine is that our bodies produce it at a steady rate, meaning it doesn't change much over time. However, the amount of serum creatinine can vary from person to person depending on the amount of muscle they have. Generally, men tend to have higher levels of serum creatinine compared to women, and during pregnancy, the levels are usually lower.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test used by doctors to measure the level of creatinine in your body. Before the test, you might be asked to avoid eating large amounts of meat or taking certain medications that can affect the results. When you go to the lab, a friendly phlebotomist will gently draw a small amount of blood from your arm. This blood sample will then be sent to the lab, where scientists will use special machines to measure the amount of creatinine in your blood, giving your doctor important information about your kidney health.
What does a creatinine of 8.7 mg/dl mean in men?
The creatinine level of 8.7 mg/dl is very high and could be life-threatening. It is important that you go to the hospital right away for immediate medical attention, and you may need dialysis treatment. Do not try to treat yourself without proper medical guidance.3,4
Is creatinine 8.7 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 8.7 in male across different ages
| Age Group | Is Creatinne of 8.7 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 8.7 in female across different ages
| Age Group | Is Creatinne of 8.7 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 8.7 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 8.7 is considered abnormal.
What could cause a creatinine level of 8.7?
- Acute kidney injury: Sudden loss of kidney function due to various reasons such as dehydration, severe infection, or medication toxicity.
- Chronic kidney disease: Long-term damage to the kidneys, usually caused by conditions like diabetes, high blood pressure, or glomerulonephritis.
- Urinary tract obstruction: Blockage in the urinary system, such as kidney stones, tumors, or an enlarged prostate gland.
- Renal artery stenosis: Narrowing of the arteries that supply blood to the kidneys, often caused by atherosclerosis.
- Glomerulonephritis: Inflammation of the kidney's filtering units (glomeruli), which can be caused by infections, immune system disorders, or certain medications.
- Polycystic kidney disease: Inherited disorder characterized by the growth of numerous cysts in the kidneys, leading to their impaired function.
- Lupus nephritis: Kidney inflammation caused by systemic lupus erythematosus (SLE), an autoimmune disease.
- Interstitial nephritis: Inflammation of the kidney's interstitial tissue, often due to allergic reactions to medications or infections.
- Multiple myeloma: Cancer of plasma cells in the bone marrow that can affect the kidneys and lead to elevated creatinine levels.
- Acute tubular necrosis: Damage to the kidney tubules, typically caused by ischemia, toxins, or certain medications.
If the creatinine value is below 1.02, it is within the normal limits.
What other tests should be done if creatinine level is 8.7?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps evaluate the levels of various electrolytes in the blood, such as sodium, potassium, and chloride, which can be affected by kidney function. Abnormal levels of electrolytes can indicate kidney dysfunction, and monitoring these levels can help guide treatment decisions and prevent complications associated with imbalances. Additionally, electrolyte imbalances can have significant effects on various body functions, including nerve conduction, muscle contraction, and fluid balance.
Blood Urea
The Blood Urea test is important because it measures the level of urea nitrogen in the blood, which is a waste product of protein metabolism. Elevated levels of blood urea indicate impaired kidney function, and when combined with a high creatinine level, it suggests severe kidney damage or failure. Therefore, the Blood Urea test provides crucial information about kidney function in individuals with high creatinine levels.
Estimated GFR
The Estimated Glomerular Filtration Rate (eGFR) test is crucial in determining how well the kidneys are functioning. A creatinine level of 8.7 mg/dl indicates severe kidney impairment, but the eGFR test provides a more accurate assessment of kidney function by considering factors such as age, sex, and race. This information is essential for diagnosing and managing kidney disease.
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 blood sugar control. High levels of creatinine indicate kidney dysfunction, which can be a complication of uncontrolled diabetes. By measuring HbA1c, healthcare professionals can assess the effectiveness of diabetes management and make necessary adjustments to prevent further kidney damage.
LDH
The LDH (lactate dehydrogenase) test is important in this scenario as it helps determine the level of tissue damage and cell death in the body. A high creatinine level indicates impaired kidney function, and LDH can provide additional information about potential underlying causes, such as kidney tissue damage. LDH levels can help guide treatment decisions and monitor the progression of the condition.
Random Sugar
The Random Sugar test is important because it helps in evaluating a person's blood sugar levels at any given time, which is crucial for diagnosing and managing diabetes. High levels of creatinine, a waste product in the blood, may indicate kidney dysfunction, and diabetes is one of the leading causes of kidney disease. Therefore, the Random Sugar test can provide valuable information for assessing both glucose control and kidney function in individuals with a creatinine level of 8.7 mg/dl.
What is the relation between creatinine and kidney function?
Creatinine, a chemical synthesized within our bodies, is consistently generated. The kidneys act as guardians, completely eliminating creatinine through urine filtration. However, if kidney functionality is impaired for any cause, creatinine levels surge. Consequently, creatinine serves as a valuable indicator for assessing kidney performance.
Why do doctors ask for GFR if my creatinine level is 8.7?
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.
