What is Creatinine?
Serum creatinine is a substance that our body produces as a result of a chemical reaction happening in our muscles. You see, our muscles have a special compound called creatine phosphate, and when it breaks down, it creates this thing called serum creatinine. Now, what's interesting is that our body makes this serum creatinine at a steady pace all the time. But here's the thing: the amount of serum creatinine we have in our blood can vary depending on the size of our muscles. For example, men usually have more serum creatinine than women because, well, they tend to have bigger muscles. And during pregnancy, the level of serum creatinine usually goes down a bit.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors evaluate how well our kidneys are functioning. Before the test, it is important to inform the healthcare provider about any medications or supplements we are taking, as some can affect the results. During the test, a healthcare professional will draw a small sample of blood from our arm using a needle. This blood sample is then sent to a laboratory, where they measure the concentration of creatinine, a waste product produced by our muscles that is filtered out by the kidneys. The results of this test can give valuable information about our kidney health and help doctors diagnose any potential kidney problems.
What does a creatinine of 7.6 mg/dl mean in men?
The normal range for creatinine in women is 0.73-1.18. A creatinine value of 7.6 mg/dl is considered very dangerous. It is strongly recommended that you go to the hospital right away for urgent treatment, which may include dialysis. Do not try to treat yourself without medical help.3,4
What does a creatinine of 7.6 mg/dl mean in women?
Creatinine levels for women usually range from 0.55 to 1.02. If your creatinine level is 7.6 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, seek medical help immediately.3,4
Is creatinine 7.6 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 7.6 in male across different ages
| Age Group | Is Creatinne of 7.6 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 7.6 in female across different ages
| Age Group | Is Creatinne of 7.6 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 7.6 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 7.6 is considered abnormal.
What could cause a creatinine level of 7.6?
- Acute kidney injury (AKI): Sudden loss of kidney function due to various reasons such as dehydration, kidney infection, or medication side effects.
- Chronic kidney disease (CKD): Long-term damage to the kidneys, often caused by conditions like diabetes or high blood pressure.
- Obstructive uropathy: Blockage or narrowing of the urinary tract, hindering the normal flow of urine and leading to increased creatinine levels.
- Glomerulonephritis: Inflammation of the kidney's filtering units, impairing their ability to remove waste products effectively.
- Renal artery stenosis: Narrowing of the arteries that supply blood to the kidneys, reducing kidney function and causing elevated creatinine levels.
- Pyelonephritis: Kidney infection that can damage the renal tubules and affect kidney function.
- Rhabdomyolysis: Severe muscle breakdown, releasing myoglobin into the bloodstream, which can damage the kidneys and result in elevated creatinine levels.
- Interstitial nephritis: Inflammation of the kidney's tubules and surrounding structures, leading to impaired kidney function.
- Tubular necrosis: Death of the cells in the kidney tubules, often caused by ischemia or toxic substances, resulting in reduced creatinine clearance.
- Nephrotic syndrome: A group of symptoms indicating kidney damage, including proteinuria, low levels of albumin, and high creatinine levels.
What other tests should be done if creatinine level is 7.6?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps assess the kidney function and overall electrolyte balance in the body. It can provide information about the levels of sodium, potassium, chloride, and bicarbonate, which are crucial for various bodily functions including nerve and muscle function, pH regulation, and fluid balance. Abnormal electrolyte levels can indicate kidney dysfunction or other underlying health issues.
Blood Urea
The blood urea test is important because it measures the level of urea nitrogen in the blood, which indicates how well the kidneys are functioning. In this case, with a high creatinine level of 7.6 mg/dl, the blood urea test can help determine if the elevated creatinine is due to kidney dysfunction or other factors. This test provides valuable information for diagnosing and monitoring kidney health.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is crucial in assessing kidney function as it estimates the volume of blood that is filtered by the kidneys per minute. A creatinine level of 7.6 mg/dl indicates severe kidney dysfunction, but the Estimated GFR test provides a more accurate measure of kidney function by taking into account factors such as age, sex, and race. This test helps determine the stage of kidney disease and guides treatment decisions.
HBA1C
The HbA1c test is important in this case as it provides a measure of the average blood sugar levels over the past 2-3 months and can help in diagnosing diabetes and monitoring its management. It can help determine if the high creatinine level is due to uncontrolled diabetes, which can lead to kidney damage. Monitoring and managing blood sugar levels through the HbA1c test can help prevent further complications.
LDH
The LDH (lactate dehydrogenase) test is important in this case because it can help determine the cause of the elevated creatinine level. LDH is an enzyme that is released into the bloodstream when there is tissue damage or injury, including kidney damage. By measuring LDH levels, it can provide valuable information about the extent of kidney damage and help guide further diagnostic and treatment decisions.
Random Sugar
A random sugar test is important in this case as it helps determine the blood glucose level at the time of testing, providing information about the person's current blood sugar control. Abnormally high random sugar levels could indicate uncontrolled diabetes, which can contribute to kidney damage and elevated creatinine levels. Monitoring blood glucose levels can help manage and prevent further complications.
What is the relation between creatinine and kidney function?
Creatinine, a substance naturally formed within the body, remains consistently produced. The kidneys diligently eliminate all creatinine through urine filtration. However, if the kidneys encounter impairment, whether it be caused by various factors, the levels of creatinine in the body escalate. Thus, employing creatinine as a means to assess kidney function proves highly advantageous.
Why do doctors ask for GFR if my creatinine level is 7.6?
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.
