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 a waste product that is produced at a steady rate. 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. Additionally, during pregnancy, the level of serum creatinine tends to be lower. So, basically, it's a natural byproduct of our muscles that can vary depending on our muscle mass and whether we're expecting a baby.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors assess how well our kidneys are functioning. Before the test, it is important to inform the doctor about any medications or supplements we are taking, as they can affect the results. On the day of the test, a small amount of blood will be drawn from a vein in our arm using a needle. This blood sample is then sent to the lab, where they measure the concentration of creatinine, a waste product produced by our muscles, in the blood. The results of this test can help doctors diagnose kidney problems or monitor the effectiveness of certain treatments.
What does a creatinine of 9.0 mg/dl mean in men?
A normal creatinine range for women is between 0.73 and 1.18. If your creatinine level is 9.0 mg/dl, it is considered life-threatening. It is highly recommended that you go to the hospital right away for immediate medical attention, and you may need dialysis. Do not try to treat yourself.3,4
What does a creatinine of 9.0 mg/dl mean in women?
A normal creatinine level for women is between 0.55 and 1.02. If your creatinine level is 9.0 mg/dl, it is considered very dangerous. It is highly recommended that you go to the hospital right away and you may require dialysis treatment. It is important not to try any self-treatment methods.3,4
Is creatinine 9.0 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 9.0 in male across different ages
| Age Group | Is Creatinne of 9.0 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 9.0 in female across different ages
| Age Group | Is Creatinne of 9.0 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 9.0 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 9.0 is considered abnormal.
What could cause a creatinine level of 9.0?
If the patient's creatinine level is above 1.02, here is a list of 10 potential causes:
- Acute kidney injury: Sudden loss of kidney function due to various reasons such as dehydration, medication side effects, or urinary tract blockage.
- Chronic kidney disease: Long-term damage to the kidneys leading to reduced function over time, often caused by conditions like diabetes or high blood pressure.
- Urinary tract obstruction: Blockage in the urinary system, such as kidney stones or tumors, preventing normal urine flow and causing increased creatinine levels.
- Glomerulonephritis: Inflammation of the tiny filters in the kidneys (glomeruli), which can impair their function and result in elevated creatinine.
- Polycystic kidney disease: Genetic disorder causing the growth of cysts in the kidneys, leading to kidney damage and elevated creatinine levels.
- Pyelonephritis: Bacterial infection of the kidneys, often originating from a urinary tract infection, which can cause kidney inflammation and impaired function.
- Interstitial nephritis: Inflammation of the kidney tubules, often due to medications, infections, or autoimmune diseases, leading to reduced kidney function and increased creatinine.
- Rhabdomyolysis: Breakdown of damaged skeletal muscle tissue, releasing toxic substances into the bloodstream that can lead to kidney damage and elevated creatinine.
- Renal artery stenosis: Narrowing of the arteries supplying blood to the kidneys, resulting in decreased blood flow and reduced kidney function.
- Hemolytic uremic syndrome: Rare condition characterized by the destruction of red blood cells, leading to kidney injury and elevated creatinine levels.
If the patient's creatinine level is below 1.02, it is within the normal limits.
What other tests should be done if creatinine level is 9.0?
Serum Electrolytes
The Serum Electrolytes test is important in this case to assess the balance of electrolytes such as sodium, potassium, and chloride. It helps determine if there is any abnormality in the levels of these electrolytes due to kidney dysfunction, which can be indicated by a high creatinine level. Abnormal electrolyte levels can have significant implications for fluid balance, nerve function, and overall health.
Blood Urea
The Blood Urea test is important in this case because it measures the amount of urea nitrogen in the blood, which is a waste product produced by the liver. A high level of creatinine indicates impaired kidney function, and the Blood Urea test helps further assess kidney health by measuring the efficiency of waste removal from the bloodstream.
Estimated GFR
The Estimated GFR test is important because it helps assess kidney function by estimating the glomerular filtration rate (GFR), which is a key indicator of how well the kidneys are filtering waste products from the blood. A creatinine level of 9.0 mg/dl suggests severe kidney dysfunction, but the Estimated GFR test provides a more precise measure of kidney function and helps guide appropriate treatment interventions.
HBA1C
The HbA1c test is important in this case as it measures the average blood sugar levels over the past 2-3 months, providing an indication of long-term glucose control. It is crucial to determine if the high creatinine level is due to uncontrolled diabetes, as poorly managed diabetes can lead to kidney damage. Monitoring HbA1c levels regularly can help in adjusting treatment plans and preventing further complications.
LDH
The LDH (lactate dehydrogenase) test is important in this case as it helps assess kidney function and diagnose the cause of elevated creatinine levels. LDH levels can indicate tissue damage or injury, including damage to the kidneys. By measuring LDH levels, healthcare professionals can gain insights into the extent of kidney damage and guide appropriate treatment decisions.
Random Sugar
The Random Sugar test is important because it helps evaluate the blood glucose level at any given time, providing valuable information about the patient's current glycemic control. In the case of a creatinine level of 9.0 mg/dl, it is crucial to assess the possibility of impaired kidney function, which can affect glucose metabolism and lead to abnormalities in blood sugar levels. The Random Sugar test aids in detecting and managing potential diabetes-related complications.
What is the relation between creatinine and kidney function?
Creatinine, a chemical synthesized within the body at a consistent pace, is efficiently eliminated by the kidneys through urination. In the instance that renal function is compromised for various causes, the levels of creatinine surge. Henceforth, utilizing creatinine as a diagnostic tool proves highly advantageous in assessing the efficacy of kidney performance.
Why do doctors ask for GFR if my creatinine level is 9.0?
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.
