What is Creatinine?
Serum creatinine is a substance that is naturally produced in our bodies as a result of a chemical called creatine phosphate found in our muscles. This creatinine is constantly generated at a steady rate. The amount of serum creatinine in our blood is influenced by the amount of muscle mass we have. In general, men tend to have higher levels of serum creatinine compared to women, while during pregnancy, the levels are usually lower. Understanding the levels of serum creatinine can help doctors assess the health of our kidneys and muscle 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 is important to avoid eating too much meat or taking certain medications that could affect the results. On the day of the test, a healthcare professional will draw a small sample of your blood, usually from a vein in your arm. This blood sample will then be sent to the lab, where scientists will use a machine to measure the concentration of creatinine in your blood. This test is commonly used to assess kidney function and can help detect any potential problems.
What does a creatinine of 1.7 mg/dl mean in men?
The normal range for creatinine in women is between 0.73 and 1.18. If a woman's creatinine level is 1.7 mg/dl, it is considered slightly high. It is recommended to perform additional tests, such as creatinine clearance, to further assess kidney function.3,4
What does a creatinine of 1.7 mg/dl mean in women?
A normal creatinine level for women is between 0.55 and 1.02. If the creatinine value is 1.7 mg/dl, it is considered mild. This could be caused by taking certain medications or dyes before a scan, herbal remedies, or taking too many vitamins. It's important to monitor the creatinine levels closely every week and consult a doctor.3,4
Is creatinine 1.7 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 1.7 in male across different ages
| Age Group | Is Creatinne of 1.7 dangerous? |
|---|---|
| 25yrs - 40 yrs | significantly high, but not dangerous, needs attention |
| 40yrs - 95 yrs | bad, needs attention, could be dangerous, Consult a doctor |
Table of danger posed by Creatinine 1.7 in female across different ages
| Age Group | Is Creatinne of 1.7 dangerous? |
|---|---|
| 25yrs - 67 yrs | bad, needs attention, could be dangerous, Consult a doctor |
| 67yrs - 95 yrs | very high - dangerous, Consult a doctor immediately |
What is the normal range and is a creatinine of 1.7 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 1.7 is considered abnormal.
What could cause a creatinine level of 1.7?
- Dehydration: Dehydration can lead to an increase in creatinine levels as there is less fluid available to flush out the waste products from the body.
- Kidney infection: Infections in the kidneys can cause inflammation and damage to the organ, resulting in elevated creatinine levels.
- Kidney stones: The presence of kidney stones can obstruct the urinary tract, leading to impaired kidney function and increased creatinine levels.
- Urinary tract obstruction: Blockage in the urinary tract, such as from an enlarged prostate or tumor, can prevent the proper elimination of waste products, leading to elevated creatinine levels.
- Chronic kidney disease: Long-term damage to the kidneys, often caused by conditions like diabetes or high blood pressure, can result in impaired kidney function and elevated creatinine levels.
- Excessive muscle breakdown: Conditions that cause muscle breakdown, such as rhabdomyolysis or severe trauma, can release creatinine into the bloodstream, increasing its levels.
- Certain medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or certain antibiotics, can cause kidney damage and subsequently raise creatinine levels.
- Glomerulonephritis: Glomerulonephritis refers to inflammation of the glomeruli in the kidneys, which can impair their ability to filter waste products effectively, leading to increased creatinine levels.
- Polycystic kidney disease: This genetic disorder causes the formation of fluid-filled cysts in the kidneys, which can progressively impair kidney function and elevate creatinine levels.
- Acute kidney injury: Sudden damage to the kidneys, often caused by severe infections, low blood flow, or certain medications, can result in a rapid increase in creatinine levels.
What other tests should be done if creatinine level is 1.7?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps evaluate the balance of electrolytes in the body, including sodium, potassium, chloride, and bicarbonate. Abnormal levels of these electrolytes can indicate kidney dysfunction, which may be the cause of the elevated creatinine level. Monitoring electrolyte levels helps guide treatment decisions and assess the overall health of the kidneys.
Blood Urea
The Blood Urea test is important because it measures the amount of urea nitrogen in the blood, which is a waste product produced by the liver. Elevated levels of blood urea can indicate impaired kidney function, as the kidneys are responsible for filtering out urea. Therefore, in the case of a creatinine level of 1.7 mg/dl, the Blood Urea test helps to assess the overall kidney health and function.
Estimated GFR
The Estimated GFR (eGFR) test is important because it helps estimate how well the kidneys are functioning by measuring the filtration rate of waste products from the blood. A creatinine level of 1.7 mg/dl suggests a potential decrease in kidney function, but the eGFR test provides a more accurate assessment of kidney health by taking into account factors such as age, gender, and race. This information is crucial for diagnosing and monitoring kidney diseases and determining appropriate treatment plans.
HBA1C
The HbA1c test is important because it measures the average blood glucose levels over the past three months, providing valuable information about long-term blood sugar control. In individuals with a high creatinine level like 1.7 mg/dl, it helps assess the risk and monitor the progression of diabetes-related kidney damage. Regular monitoring of HbA1c levels is crucial in managing diabetes and preventing complications.
LDH
The LDH (lactate dehydrogenase) test is important in this case because it helps assess kidney function and diagnose potential kidney damage or disease. Elevated levels of LDH can indicate kidney injury or impaired renal function, which could be contributing to the increased creatinine level of 1.7 mg/dl. Therefore, the LDH test can provide additional information to aid in the evaluation and management of the patient's condition.
Random Sugar
The Random Sugar test is important to determine if the high creatinine level is due to impaired kidney function or uncontrolled diabetes. A high random sugar level would suggest uncontrolled diabetes, which can contribute to kidney damage. This test helps in identifying the underlying cause of elevated creatinine and guides appropriate treatment.
What is the relation between creatinine and kidney function?
Creatinine, a substance synthesized within the body with unwavering consistency, undergoes full filtration by the kidneys into urine. In the unfortunate event that kidney functionality is impaired, creatinine levels ascend. Consequently, creatinine serves as an invaluable means to assess the well-being of our kidneys.
Why do doctors ask for GFR if my creatinine level is 1.7?
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.
