What is Creatinine?
Serum creatinine is a substance that our bodies naturally make as a result of a chemical called creatine phosphate found in our muscles. It's like a leftover byproduct that our bodies produce at a steady pace. The amount of serum creatinine we have in our blood is influenced by how much muscle we have. Generally, men tend to have more serum creatinine than women because they typically have more muscle mass. On the other hand, during pregnancy, the levels of serum creatinine tend to be lower.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps measure the level of creatinine in your body. Before the test, it's important to let your healthcare provider know about any medications or supplements you are taking, as they may affect the results. On the day of the test, a healthcare professional will draw a small amount of blood from your arm using a needle. This blood sample will then be sent to a lab, where they will measure the concentration of creatinine in it. The results of this test can give your doctor important information about how well your kidneys are functioning.
What does a creatinine of 8.6 mg/dl mean in women?
The normal range for creatinine in women is between 0.55 and 1.02. A creatinine value of 8.6 mg/dl is considered very dangerous. It is highly recommended that you go to the hospital right away and you may require dialysis. It is important not to try to treat yourself with any medications.3,4
Is creatinine 8.6 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 8.6 in male across different ages
| Age Group | Is Creatinne of 8.6 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 8.6 in female across different ages
| Age Group | Is Creatinne of 8.6 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 8.6 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 8.6 is considered abnormal.
What could cause a creatinine level of 8.6?
- Acute kidney injury: Sudden loss of kidney function due to various causes such as dehydration, kidney infection, or medication side effects.
- Chronic kidney disease: Long-term damage to the kidneys, often caused by conditions like high blood pressure or diabetes.
- Renal artery stenosis: Narrowing of the arteries that supply blood to the kidneys, leading to reduced kidney function.
- Polycystic kidney disease: Inherited disorder causing multiple cysts to form in the kidneys, impairing their function over time.
- Urinary tract obstruction: Blockage in the urinary tract, such as kidney stones or tumors, preventing normal urine flow and causing kidney damage.
- Glomerulonephritis: Inflammation of the kidney's filtering units (glomeruli), often caused by immune system disorders or infections.
- Interstitial nephritis: Inflammation of the kidney's tubules and surrounding structures, commonly due to allergic reactions or certain medications.
- Hemolytic uremic syndrome: Rare condition causing abnormal destruction of red blood cells, leading to kidney failure.
- Systemic lupus erythematosus: Autoimmune disease where the immune system attacks various organs, including the kidneys.
- Nephrotic syndrome: Kidney disorder characterized by excessive protein leakage into the urine, resulting in low protein levels and edema.
What other tests should be done if creatinine level is 8.6?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps assess the balance of electrolytes in the body, including potassium, sodium, and chloride. Abnormal levels of these electrolytes can indicate kidney dysfunction, which may be the cause of the high creatinine level. Monitoring electrolyte levels is crucial in managing kidney function and determining appropriate treatment options.
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 during the breakdown of protein. Elevated levels of blood urea indicate impaired kidney function, and in conjunction with a high creatinine level, it can help diagnose and monitor kidney diseases or conditions.
Estimated GFR
The Estimated Glomerular Filtration Rate (eGFR) test is crucial in assessing kidney function as it estimates the rate at which the kidneys filter waste products from the blood. A creatinine level of 8.6 mg/dl indicates severe kidney dysfunction, but eGFR provides a more accurate measure of kidney function, aiding in the diagnosis and management of kidney disease. eGFR is essential for determining the stage of kidney disease and guiding appropriate treatment decisions.
HBA1C
The HbA1c test is important because it measures the average blood sugar level over the past 2-3 months, providing information about long-term blood sugar control. In this case, with a creatinine level of 8.6 mg/dl, the HbA1c test can help determine if the elevated creatinine is due to uncontrolled diabetes, which could contribute to kidney damage. Monitoring and managing blood sugar levels through the HbA1c test is crucial in preventing further complications.
LDH
The LDH test is important in this case because it can help determine the underlying cause of the elevated creatinine level. LDH levels can indicate tissue damage or cell death, which may be contributing to the high creatinine. By measuring LDH levels, healthcare providers can gain insights into the severity and extent of tissue damage, aiding in the diagnosis and management of the patient's condition.
Random Sugar
The Random Sugar test is important because it helps to assess a person's blood sugar levels at a given moment, which can be crucial in determining if there is underlying diabetes or impaired glucose tolerance. High levels of creatinine, such as 8.6 mg/dl, may indicate kidney dysfunction, which can affect the body's ability to regulate blood sugar levels. Therefore, the Random Sugar test can provide valuable information for diagnosing and managing potential diabetes or related conditions.
What is the relation between creatinine and kidney function?
Creatinine, a nifty compound, emerges within our bodies with unwavering consistency. Our kidneys, acting as diligent custodians, diligently strain out creatinine, expelling it entirely through the urine. However, should our kidney's performance waver, for any number of reasons, creatinine levels experience a notable surge. Consequently, creatinine serves as an invaluable gauge to scrutinize the efficacy of our kidney function.
Why do doctors ask for GFR if my creatinine level is 8.6?
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.
