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's kind of like a leftover product that our bodies make when we use our muscles. The interesting thing about serum creatinine is that our bodies make it at a steady pace, meaning it doesn't really change much unless something unusual is happening. The amount of serum creatinine we have in our bodies depends on how much muscle mass we have. Men usually have more serum creatinine than women because they tend to have more muscle. And interestingly, 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 doctors assess kidney function. Before the test, it is important to inform the healthcare provider about any medications or supplements being taken, as they can affect the results. On the day of the test, a healthcare professional will draw a small amount of blood from a vein in the arm using a needle and collect it in a special tube. This blood sample is then sent to the lab, where advanced machines measure the concentration of creatinine in the blood. This test helps doctors determine if the kidneys are working properly or if there may be any kidney-related health concerns.
What does a creatinine of 9.4 mg/dl mean in men?
The normal range for creatinine in women is 0.73-1.18. A creatinine value of 9.4 mg/dl is considered very dangerous. It is strongly advised that you go to the hospital right away and you may require dialysis. It is important not to try to treat yourself without medical help.3,4
What does a creatinine of 9.4 mg/dl mean in women?
The normal range for creatinine in women is between 0.55 and 1.02. A creatinine value of 9.4 mg/dl is considered very dangerous. It is highly recommended that you go to the hospital right away and you may need dialysis. Do not try to treat yourself.3,4
Is creatinine 9.4 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 9.4 in male across different ages
| Age Group | Is Creatinne of 9.4 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 9.4 in female across different ages
| Age Group | Is Creatinne of 9.4 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 9.4 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 9.4 is considered abnormal.
What could cause a creatinine level of 9.4?
- Acute kidney injury: A sudden loss of kidney function due to various causes such as dehydration, severe infection, or medication toxicity.
- Chronic kidney disease: A long-term condition where the kidneys gradually lose their function, often caused by conditions like high blood pressure or diabetes.
- Urinary tract obstruction: Blockage of the urinary tract, such as from kidney stones or tumors, can lead to increased creatinine levels.
- Glomerulonephritis: Inflammation of the glomeruli, the tiny filters in the kidneys, can impair their ability to remove waste products from the blood.
- Polycystic kidney disease: A genetic disorder where cysts develop in the kidneys, leading to kidney damage and elevated creatinine levels.
- Pyelonephritis: A severe kidney infection that can cause inflammation and damage to the kidneys.
- Drug-induced nephrotoxicity: Certain medications, like nonsteroidal anti-inflammatory drugs (NSAIDs) or some antibiotics, can harm the kidneys and result in increased creatinine levels.
- Hemolytic uremic syndrome: A condition characterized by the destruction of red blood cells, which can lead to kidney injury and elevated creatinine levels.
- Rhabdomyolysis: A breakdown of muscle tissue that releases harmful substances into the blood, potentially leading to kidney damage and increased creatinine levels.
- Renal artery stenosis: A narrowing of the arteries that supply blood to the kidneys, causing reduced kidney function and elevated creatinine levels.
What other tests should be done if creatinine level is 9.4?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it can help determine the balance of electrolytes such as sodium, potassium, and chloride in the body. Elevated creatinine levels can indicate kidney dysfunction, and imbalances in electrolytes can further contribute to kidney damage. Monitoring electrolyte levels can assist in managing and preventing complications associated with kidney dysfunction.
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 protein metabolism. High levels of urea nitrogen in the blood can indicate impaired kidney function, as the kidneys are responsible for filtering out waste products like urea. Therefore, the blood urea test complements the creatinine test by providing additional information about kidney function.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in assessing kidney function, especially in individuals with a high creatinine level like 9.4 mg/dl. It provides an estimate of the rate at which the kidneys are filtering waste from the blood, allowing healthcare professionals to diagnose and monitor kidney disease. This information helps guide appropriate treatment and management strategies to prevent further decline in kidney function.
HBA1C
The HbA1c test is important in this case because it measures the average blood sugar levels over the past 2-3 months, providing a more comprehensive assessment of diabetes control compared to a single blood glucose reading. With a creatinine level of 9.4 mg/dl, which indicates impaired kidney function, it is crucial to monitor long-term blood sugar control as uncontrolled diabetes can further damage the kidneys. The HbA1c test helps healthcare professionals determine appropriate treatment strategies and monitor the effectiveness of interventions in managing diabetes and preventing further complications.
LDH
The LDH (lactate dehydrogenase) test is important in this case because it helps determine the cause of the high creatinine level. LDH is an enzyme found in many tissues, including the kidneys, and elevated levels may indicate kidney damage. By measuring LDH, healthcare providers can gain insights into the underlying condition contributing to the high creatinine, enabling appropriate diagnosis and treatment decisions.
Random Sugar
The Random Sugar test is important in this case because it helps to assess the patient's blood glucose levels at any given time, indicating if they have diabetes or if their diabetes is well-controlled. A high creatinine level indicates kidney dysfunction, which can be a complication of uncontrolled diabetes. Therefore, the Random Sugar test can provide valuable information for managing the patient's diabetes and preventing further kidney damage.
What is the relation between creatinine and kidney function?
Creatinine, a chemical synthesized consistently within the body, undergoes total filtration by the kidneys into urine. In the event of kidney dysfunction caused by various factors, creatinine levels experience a surge. Consequently, measuring creatinine serves as an invaluable means to assess kidney functionality.
Why do doctors ask for GFR if my creatinine level is 9.4?
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.
