What is Creatinine?
Serum creatinine is a substance that our body naturally produces as a result of a chemical called creatine phosphate found in our muscles. It is made steadily at a constant rate, meaning our body creates a consistent amount of it over time. The amount of serum creatinine in our blood is influenced by the size of our muscles, so it tends to be higher in men compared to women. Interestingly, during pregnancy, the levels of serum creatinine are generally lower. Overall, serum creatinine is a helpful marker that doctors use to assess our kidney function.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 inform your doctor about any medications you are taking as some may interfere with the results. On the day of the test, you will be asked to provide a blood sample, which is usually taken from a vein in your arm. In the lab, the blood sample will be analyzed to determine the concentration of creatinine, a waste product produced by our muscles. This measurement helps doctors assess how well your kidneys are functioning and detect any potential kidney problems.
What does a creatinine of 9.3 mg/dl mean in men?
The normal range for creatinine in women is between 0.73 and 1.18. A creatinine value of 9.3 mg/dl is considered very dangerous. It is highly recommended that you go to the hospital right away for immediate medical attention and possible dialysis. Do not try to treat yourself with medication.3,4
What does a creatinine of 9.3 mg/dl mean in women?
The normal range for creatinine in women is 0.55-1.02. If your creatinine level is 9.3 mg/dl, it is considered very dangerous. It is suggested that you go to the hospital right away and you may need dialysis. It is important not to try to treat yourself.3,4
Is creatinine 9.3 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 9.3 in male across different ages
| Age Group | Is Creatinne of 9.3 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 9.3 in female across different ages
| Age Group | Is Creatinne of 9.3 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 9.3 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 9.3 is considered abnormal.
What could cause a creatinine level of 9.3?
- Acute kidney injury (AKI): A sudden loss of kidney function, often caused by dehydration, infection, or medication side effects.
- Chronic kidney disease (CKD): A long-term condition where the kidneys gradually lose their function, usually due to conditions like diabetes or high blood pressure.
- Obstructive kidney disease: A blockage in the urinary tract that prevents urine from flowing properly, leading to a buildup of waste products in the body.
- Polycystic kidney disease (PKD): A genetic disorder characterized by the growth of numerous cysts in the kidneys, which can impair their function.
- Glomerulonephritis: Inflammation of the glomeruli, the tiny filters in the kidneys responsible for removing waste and excess fluid from the blood.
- Nephrotic syndrome: A condition that causes the kidneys to leak large amounts of protein into the urine, resulting in swelling, high cholesterol, and low protein levels in the blood.
- Renal artery stenosis: Narrowing of the arteries that supply blood to the kidneys, leading to reduced blood flow and impaired kidney function.
- Tubulointerstitial nephritis: Inflammation of the tubules and interstitium within the kidneys, often caused by medications, infections, or autoimmune diseases.
- Rhabdomyolysis: A condition in which damaged muscle tissue releases harmful substances into the bloodstream, potentially causing kidney damage.
- Tumor lysis syndrome: A complication of cancer treatment, where the breakdown of cancer cells leads to the release of large amounts of waste products, overwhelming the kidneys.
What other tests should be done if creatinine level is 9.3?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps evaluate the balance of electrolytes in the body, such as sodium, potassium, and chloride. A high creatinine level may indicate kidney dysfunction, which can disrupt electrolyte levels. Monitoring electrolytes is crucial for maintaining proper functioning of various bodily processes and preventing complications associated with imbalances.
Blood Urea
The Blood Urea test is important because it helps to evaluate kidney function. In the case of a creatinine level of 9.3 mg/dl, the Blood Urea test can provide additional information about the efficiency of the kidneys in filtering and eliminating waste products from the body. This test can help in diagnosing and monitoring kidney disease or dysfunction.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in this case because it provides an estimate of kidney function. A creatinine level of 9.3 mg/dL indicates severe kidney impairment, but the Estimated GFR test can provide a more accurate assessment of the extent of the impairment, helping to guide treatment decisions. This test is crucial in determining the stage of chronic kidney disease and monitoring its progression.
HBA1C
The HbA1c test is important in this case because it provides an estimation of average blood glucose levels over the past 2-3 months. It helps to monitor long-term glycemic control and is commonly used in the diagnosis and management of diabetes. With a high creatinine level, it is crucial to assess and monitor the patient's blood glucose levels to identify and manage any potential diabetes-related complications.
LDH
The LDH (lactate dehydrogenase) test is important in this case because it helps determine the extent of tissue damage or injury. Elevated LDH levels can indicate cellular damage in organs such as the kidneys, liver, or heart, which could be contributing to the high creatinine levels. Thus, the LDH test assists in identifying the underlying cause of the elevated creatinine and guiding appropriate treatment decisions.
Random Sugar
The Random Sugar test is important because it helps determine if the high creatinine level is due to kidney dysfunction or uncontrolled diabetes. If the Random Sugar test shows elevated blood sugar levels, it suggests that the high creatinine is likely a result of uncontrolled diabetes. This information is crucial for determining the appropriate treatment approach.
What is the relation between creatinine and kidney function?
Creatinine, a chemical that our bodies consistently generate, is wholly eliminated in urine by our kidneys. When kidney function is compromised for any cause, creatinine levels escalate, making it an invaluable measure for assessing kidney performance.
Why do doctors ask for GFR if my creatinine level is 9.3?
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.
