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 produced at a steady pace, meaning it remains fairly consistent over time. The amount of serum creatinine in our blood is influenced by the amount of muscle mass we have - generally, men tend to have higher levels of serum creatinine compared to women. Additionally, during pregnancy, the levels of serum creatinine are usually lower. These factors help doctors understand and evaluate the health of our muscles and kidneys.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps to measure the level of creatinine in your body. Before the test, there is usually no need for any special preparation. On the day of the test, a healthcare professional will gently insert a small needle into your arm to draw a small amount of blood. This blood sample is then sent to the lab, where they use a machine to measure the concentration of creatinine in your blood. This test helps doctors assess how well your kidneys are functioning and can provide important information about your overall health.
What does a creatinine of 9.9 mg/dl mean in men?
The normal range for creatinine in women is between 0.73 and 1.18. When the creatinine level is 9.9 mg/dl, it is considered life-threatening. It is strongly recommended that you go to the hospital right away and you may need dialysis. Do not try to treat yourself.3,4
Is creatinine 9.9 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 9.9 in male across different ages
| Age Group | Is Creatinne of 9.9 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
Table of danger posed by Creatinine 9.9 in female across different ages
| Age Group | Is Creatinne of 9.9 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |
What is the normal range and is a creatinine of 9.9 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 9.9 is considered abnormal.
What could cause a creatinine level of 9.9?
- Acute kidney injury: Acute kidney injury can cause a sudden increase in creatinine levels. It may be caused by factors such as dehydration, low blood flow to the kidneys, or certain medications.
- Chronic kidney disease: Chronic kidney disease is a long-term condition where the kidneys gradually lose their function. It can lead to an increase in creatinine levels over time.
- Urinary tract obstruction: Blockages in the urinary tract, such as kidney stones or tumors, can prevent normal urine flow and cause a buildup of creatinine in the blood.
- Glomerulonephritis: Glomerulonephritis is a condition characterized by inflammation of the glomeruli, which are tiny filters in the kidneys. This inflammation can impair kidney function and result in elevated creatinine levels.
- Polycystic kidney disease: Polycystic kidney disease is a genetic disorder that causes numerous fluid-filled cysts to develop in the kidneys. Over time, these cysts can impair kidney function and increase creatinine levels.
- Interstitial nephritis: Interstitial nephritis is inflammation of the kidney's tubules and surrounding tissue. It can be caused by certain medications, infections, or autoimmune diseases, and can lead to elevated creatinine levels.
- Renal artery stenosis: Renal artery stenosis is a narrowing of the arteries that supply blood to the kidneys. This can reduce blood flow to the kidneys and result in an increase in creatinine levels.
- Multiple myeloma: Multiple myeloma is a type of cancer that affects plasma cells in the bone marrow. It can lead to kidney damage and elevated creatinine levels.
- Rhabdomyolysis: Rhabdomyolysis is a condition characterized by the breakdown of muscle tissue, which releases myoglobin into the bloodstream. Myoglobin can damage the kidneys and cause an increase in creatinine levels.
- Hemolytic uremic syndrome: Hemolytic uremic syndrome is a rare condition that can occur after certain types of bacterial infections. It can cause damage to the small blood vessels in the kidneys and result in elevated creatinine levels.
What other tests should be done if creatinine level is 9.9?
Serum Electrolytes
A creatinine level of 9.9 mg/dl is significantly elevated, indicating severe kidney dysfunction or failure. Serum electrolytes test is crucial as it measures the levels of essential minerals like sodium, potassium, and chloride, which can be imbalanced due to impaired kidney function. Electrolyte imbalances can lead to serious complications such as irregular heart rhythms, muscle weakness, and neurological problems.
Blood Urea
The blood urea test is important in this case because it helps assess the kidney function and determine the severity of kidney damage. A high level of creatinine indicates impaired kidney function, and the blood urea test measures the amount of urea nitrogen in the blood, which also increases when the kidneys are not functioning properly. Therefore, the blood urea test provides additional information about the extent of kidney dysfunction in conjunction with the creatinine level.
Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in assessing kidney function as it estimates the rate at which the kidneys filter waste products from the blood. A creatinine level of 9.9 mg/dl indicates severe kidney impairment, but the Estimated GFR provides a more precise measure of kidney function and helps determine the stage of chronic kidney disease. This information is crucial for evaluating treatment options and making informed decisions for patient care.
HBA1C
The HbA1c test is important in this case because it measures the average blood glucose levels over the past 2-3 months, providing crucial information about long-term blood sugar control. It helps in diagnosing and monitoring diabetes, as well as evaluating the effectiveness of treatment plans. This test is particularly significant in patients with high creatinine levels, as it can help assess the impact of diabetes on kidney function.
LDH
The LDH (lactate dehydrogenase) test is important in this case as it helps determine the cause of the elevated creatinine level. LDH is an enzyme found in many organs, including the kidneys, and its levels can increase in conditions that cause kidney damage, such as kidney failure or rhabdomyolysis. By measuring LDH levels, healthcare professionals can gain insights into the underlying cause of the elevated creatinine and guide appropriate treatment decisions.
Random Sugar
The Random Sugar test is important because it helps evaluate a person's blood sugar level at any given time, regardless of when they last ate. This test is particularly crucial in the case of a high creatinine level of 9.9 mg/dl, as it can help diagnose or monitor diabetes, which can be a possible cause of elevated creatinine levels. Additionally, it can assist in assessing the overall kidney function and the potential impact of high blood sugar on renal health.
What is the relation between creatinine and kidney function?
Creatinine, a substance concocted within the body, merrily springs forth at a fixed pace. The kidney, being the diligent gatekeeper it is, sieves out all traces of creatinine, leaving none behind in the golden streams of urine. However, should the kidney's duties be hindered for any mysterious cause, the levels of creatinine joyfully soar, alerting us to their mischievous mischief. Henceforth, creatinine, in its wondrous ways, proves to be a most resourceful tool in assessing the kidney's performance.
Why do doctors ask for GFR if my creatinine level is 9.9?
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.
