What is Creatinine?
Serum creatinine is a substance that is naturally made in our bodies as a leftover product when our muscles use up a compound called creatine phosphate. It is produced at a steady pace, meaning our bodies consistently create the same amount over time. The level of serum creatinine in our blood depends on how much muscle we have – generally, men tend to have higher levels than women because they typically have more muscle mass. However, during pregnancy, the level of serum creatinine tends to be lower than usual.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors check how well your kidneys are working. Before the test, you might be asked to avoid eating certain foods or taking certain medicines to get accurate results. When you go to the lab, a healthcare professional will clean your arm with a small needle and draw a small amount of blood. This blood sample will then be sent to the lab, where they will measure the amount of creatinine in it to determine if your kidneys are functioning properly.
What does a creatinine of 9.1 mg/dl mean in men?
The normal range for creatinine in women is 0.73-1.18. If your creatinine level is 9.1 mg/dl, it is considered very dangerous. It is highly recommended that you go to the hospital right away for treatment, and you may require dialysis. It is important not to try to treat yourself.3,4
What does a creatinine of 9.1 mg/dl mean in women?
The normal range for creatinine in women is between 0.55 and 1.02. If your creatinine value is 9.1 mg/dl, it is considered life-threatening. It is strongly recommended 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 9.1 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 9.1 in male across different ages
| Age Group | Is Creatinne of 9.1 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 9.1 in female across different ages
| Age Group | Is Creatinne of 9.1 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 9.1 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 9.1 is considered abnormal.
What could cause a creatinine level of 9.1?
- Acute kidney injury (AKI): A sudden decrease in kidney function due to various causes such as dehydration, medication side effects, or urinary tract obstruction.
- Chronic kidney disease (CKD): Long-term damage to the kidneys often caused by conditions like diabetes or high blood pressure.
- Renal failure: The kidneys are unable to adequately filter waste products from the blood, leading to a buildup of toxins.
- Kidney infection: Inflammation and infection of the kidneys, usually caused by bacteria entering the urinary tract.
- Glomerulonephritis: Inflammation of the glomeruli, the tiny filters in the kidneys, which can impair their function.
- Obstructive nephropathy: Blockage in the urinary tract, such as kidney stones or an enlarged prostate, leading to impaired kidney function.
- Nephrotic syndrome: A kidney disorder characterized by excessive protein loss in the urine, resulting in decreased kidney function.
- Rhabdomyolysis: Severe muscle breakdown releasing toxins into the bloodstream, which can damage the kidneys.
- Hemolytic uremic syndrome (HUS): A condition characterized by the destruction of red blood cells, low platelet count, and kidney injury.
- Multiple myeloma: A type of cancer that affects plasma cells and can lead to kidney damage.
What other tests should be done if creatinine level is 9.1?
Serum Electrolytes
The Serum Electrolytes test is important because it helps assess the balance of important minerals in the body, such as sodium, potassium, and chloride. Abnormal levels of these electrolytes can indicate kidney dysfunction, which could be the cause of the high creatinine level. Monitoring electrolyte levels can help guide treatment decisions and prevent complications.
Blood Urea
The blood urea test is important in this case because it helps evaluate kidney function by measuring the amount of urea nitrogen in the blood. A high creatinine level indicates impaired kidney function, and the blood urea test provides additional information on how well the kidneys are able to filter waste products from the body. Therefore, the blood urea test is crucial in assessing the severity of kidney dysfunction and guiding appropriate treatment decisions.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in this case because it helps to assess kidney function by estimating the rate at which the kidneys filter waste products from the blood. A creatinine level of 9.1 mg/dl indicates severe kidney dysfunction, but the Estimated GFR test provides a more accurate and comprehensive evaluation of kidney function, allowing for better management and treatment decisions.
HBA1C
The HBA1C test is important in this case as it measures the average blood sugar levels over a period of three months, providing information about long-term blood sugar control. This test can help determine if the high creatinine level is due to poorly controlled diabetes, which can lead to kidney damage. Monitoring HBA1C levels can guide treatment decisions and interventions to prevent 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 levels can be elevated in conditions such as kidney damage, muscle injury, or hemolysis, which can all contribute to increased creatinine levels. By measuring LDH, healthcare professionals can gain insights into the underlying condition and guide appropriate treatment.
Random Sugar
The Random Sugar test is important because it helps to assess the patient's blood glucose levels at a specific point in time, which can be useful in diagnosing and monitoring conditions such as diabetes. High creatinine levels can be indicative of kidney dysfunction, which can also affect blood sugar regulation. Therefore, the Random Sugar test can provide additional information about the patient's overall health status and guide appropriate treatment interventions.
What is the relation between creatinine and kidney function?
Creatinine, a compound synthesized within the body at a steady pace, is entirely eliminated in the urine by the kidney. However, if the kidney's functionality is compromised for various causes, the levels of creatinine surge. Consequently, creatinine serves as an immensely valuable approach to assess the performance of the kidney.
Why do doctors ask for GFR if my creatinine level is 9.1?
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.
