What is Creatinine?
Serum creatinine is a substance that is naturally made in our bodies as a result of a chemical called creatine phosphate found in our muscles. It is created at a steady pace and serves as a byproduct of muscle activity. The amount of serum creatinine in our blood is influenced by our muscle mass, meaning that individuals with more muscles tend to have higher levels of serum creatinine. This is why men generally have higher levels than women. Interestingly, during pregnancy, the levels of serum creatinine tend to be lower, possibly due to changes happening in the body during that time.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors assess kidney function. Before the test, you might be asked to avoid eating certain foods or taking specific medications, as they can affect the results. When you go to the lab, a healthcare professional will draw a small amount of blood from your arm using a needle. This blood sample will then be sent to the lab, where they will measure the level of creatinine, a waste product produced by your muscles, in your blood. This information helps the doctor understand how well your kidneys are working.
What does a creatinine of 7.9 mg/dl mean in men?
The normal range for creatinine in women is between 0.73 and 1.18. If your creatinine level is 7.9 mg/dl, it is considered very dangerous. It is highly recommended that you go to the hospital right away and you may need dialysis treatment. Do not try to treat yourself without medical assistance.3,4
What does a creatinine of 7.9 mg/dl mean in women?
The normal range for creatinine in women is between 0.55 and 1.02. If your creatinine value is 7.9 mg/dl, it is considered very dangerous for your health. It is strongly advised that you go to the hospital right away, as you may require immediate admission and dialysis. It is important not to try treating yourself and seek professional medical help.3,4
Is creatinine 7.9 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 7.9 in male across different ages
| Age Group | Is Creatinne of 7.9 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 7.9 in female across different ages
| Age Group | Is Creatinne of 7.9 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 7.9 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 7.9 is considered abnormal.
What could cause a creatinine level of 7.9?
- Acute kidney injury (AKI): This is a sudden loss of kidney function caused by factors such as dehydration, severe infection, or medication toxicity.
- Chronic kidney disease (CKD): A long-term condition where the kidneys gradually lose their ability to function properly.
- Obstruction of the urinary tract: Blockage in the urinary system, such as kidney stones or an enlarged prostate, can lead to elevated creatinine levels.
- Glomerulonephritis: Inflammation of the tiny filters in the kidneys, known as glomeruli, can impair kidney function and result in increased creatinine levels.
- Pyelonephritis: A bacterial infection of the kidneys that can cause inflammation and damage to the renal tissues.
- Nephrotic syndrome: A condition characterized by excessive protein loss in the urine, often associated with kidney damage.
- Rhabdomyolysis: A breakdown of muscle tissue that releases myoglobin into the bloodstream, which can damage the kidneys and raise creatinine levels.
- Dehydration: Insufficient fluid intake or excessive fluid loss can lead to concentrated urine, resulting in higher creatinine levels.
- Heart failure: Reduced blood flow to the kidneys due to a weakened heart can impair renal function and elevate creatinine levels.
- Hypothyroidism: An underactive thyroid gland can affect kidney function and result in elevated creatinine levels.
What other tests should be done if creatinine level is 7.9?
Serum Electrolytes
The Serum Electrolytes test is important for a creatinine level of 7.9 mg/dl as it helps evaluate the balance of important electrolytes like sodium, potassium, and chloride in the body. Imbalances in electrolytes can lead to complications such as dehydration, muscle weakness, and cardiac arrhythmias, which can be life-threatening. Monitoring electrolyte levels can guide appropriate treatment and help prevent further complications.
Blood Urea
The Blood Urea test is important in this case because it helps in assessing kidney function. A high creatinine level indicates impaired kidney function, and the Blood Urea test measures the amount of urea nitrogen in the blood, which is a waste product filtered by the kidneys. Monitoring the Blood Urea levels can provide additional information about kidney health and aid in the diagnosis and management of kidney disease.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in assessing kidney function as it provides an estimation of the amount of blood filtered by the kidneys per minute. A creatinine level of 7.9 mg/dl indicates severe kidney impairment, but the Estimated GFR test can provide a more accurate measure of kidney function, aiding in the diagnosis, treatment, and monitoring of kidney disease. This test is crucial in determining the stage of kidney disease and guiding appropriate medical interventions.
HBA1C
The HbA1c test is important in this case because it measures the average blood glucose levels over a period of 2-3 months, providing valuable information about long-term blood sugar control. This test can help determine if the high creatinine level is a result of uncontrolled diabetes, as persistently elevated blood sugar levels can lead to kidney damage. Monitoring and managing blood glucose levels through the HbA1c test can potentially prevent or slow down the progression of kidney disease.
LDH
The LDH test is important in this case because it helps to assess the extent of tissue damage or injury. Elevated levels of LDH can indicate tissue breakdown and cell death, which may be contributing to the high creatinine levels. Understanding the level of tissue damage can aid in diagnosing and managing the underlying condition causing the elevated creatinine levels.
Random Sugar
The Random Sugar test is important in this case because it helps determine the patient's blood glucose levels at a specific moment, providing information about their current glycemic control. This test is crucial because high blood glucose levels can lead to kidney damage, and since creatinine is a marker of kidney function, it is necessary to assess the patient's blood sugar levels to better understand the potential impact on their kidney health.
What is the relation between creatinine and kidney function?
Creatinine, a chemical constantly generated in the body, is excreted entirely in urine after being filtered by the kidney. When kidney function is compromised for various reasons, creatinine levels elevate. Consequently, creatinine serves as a valuable means to assess kidney performance.
Why do doctors ask for GFR if my creatinine level is 7.9?
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.
