What is Creatinine?
Serum creatinine is a substance that our bodies naturally produce as a result of a chemical called creatine phosphate in our muscles. It is created at a steady pace, meaning it is produced at the same rate all the time. The amount of serum creatinine in our blood is influenced by our muscle mass, which means that people with more muscles tend to have higher levels of it. Additionally, it has been observed that men generally have higher levels of serum creatinine compared to women, while it is usually lower in pregnant women.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors measure the level of creatinine in your body. Before the test, it's important to inform your doctor about any medications or supplements you're taking, as they might affect the results. On the day of the test, you'll visit the lab where a healthcare professional will draw a small sample of your blood using a needle. This blood sample will then be sent to the lab where scientists will use special instruments to measure the concentration of creatinine in your blood.
What does a creatinine of 2.0 mg/dl mean in men?
A creatinine value of 2.0 mg/dl, which is considered mild, can be caused by taking certain medications, using dyes for medical scans, or using herbal medicines or vitamins excessively. It is important to regularly check and monitor creatinine levels, and it is recommended to consult a doctor for further guidance.3,4
What does a creatinine of 2.0 mg/dl mean in women?
A slight increase in creatinine levels can happen if you have taken certain medications or dyes before getting a scan. It can also be caused by herbal medicines or taking too many vitamins. It is important to keep a close eye on your creatinine levels by getting them checked once a week. It is recommended to talk to a doctor about this.3,4
Is creatinine 2.0 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 2.0 in male across different ages
| Age Group | Is Creatinne of 2.0 dangerous? |
|---|---|
| 25yrs - 95 yrs | bad, needs attention, could be dangerous, Consult a doctor |
Table of danger posed by Creatinine 2.0 in female across different ages
| Age Group | Is Creatinne of 2.0 dangerous? |
|---|---|
| 25yrs - 27 yrs | bad, needs attention, could be dangerous, Consult a doctor |
| 27yrs - 95 yrs | very high - dangerous, Consult a doctor immediately |
What is the normal range and is a creatinine of 2.0 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 2.0 is considered abnormal.
What could cause a creatinine level of 2.0?
- Dehydration: Dehydration can cause an increase in creatinine levels as the body tries to conserve water.
- Chronic kidney disease: This condition leads to impaired kidney function, resulting in elevated creatinine levels.
- Acute kidney injury: Sudden damage to the kidneys can cause a rapid rise in creatinine levels.
- Urinary tract obstruction: Blockages in the urinary tract can prevent the normal excretion of creatinine, leading to its accumulation.
- Certain medications: Some medications, such as NSAIDs or certain antibiotics, can cause an increase in creatinine levels.
- Muscle disorders: Conditions like rhabdomyolysis, where muscle breakdown occurs, can elevate creatinine levels.
- High protein diet: Consuming excessive amounts of protein can temporarily raise creatinine levels.
- Severe infection: Infections, particularly those affecting the kidneys, can lead to elevated creatinine levels.
- Heart failure: Decreased blood flow to the kidneys due to heart failure can cause an increase in creatinine levels.
- Liver disease: Impaired liver function can affect the body's ability to eliminate creatinine, resulting in higher levels.
What other tests should be done if creatinine level is 2.0?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps evaluate the kidney function and assess the balance of electrolytes in the body. A creatinine level of 2.0 mg/dl indicates impaired kidney function, and the electrolyte levels can provide crucial information about the patient's overall health and help guide treatment decisions. Monitoring electrolyte levels is essential to prevent complications related to kidney dysfunction and maintain proper bodily functions.
Blood Urea
The blood urea test is important because it measures the amount of urea nitrogen in the blood, which reflects the functioning of the kidneys. Elevated creatinine levels, like 2.0 mg/dl, indicate impaired kidney function, and the blood urea test helps confirm renal dysfunction by measuring the levels of urea, a waste product filtered by the kidneys. Monitoring blood urea levels is crucial for diagnosing and managing kidney diseases.
Estimated GFR
The Estimated Glomerular Filtration Rate (eGFR) test is crucial in assessing kidney function as it estimates the rate at which the kidneys filter waste products from the blood. A creatinine level of 2.0 mg/dl indicates impaired kidney function, but the eGFR test provides a more comprehensive understanding of the severity of kidney damage and helps guide appropriate treatment interventions. It is essential for monitoring kidney health, identifying chronic kidney disease, and determining the stage of kidney dysfunction.
HBA1C
The HBA1C test is important in this case as it can provide information about the average blood sugar levels over the past 2-3 months, indicating the long-term control of diabetes. It helps in assessing the risk of complications such as kidney damage, which can be indicated by elevated creatinine levels. Monitoring HBA1C levels can guide treatment decisions and interventions to improve diabetes management and prevent further complications.
LDH
The LDH test is important in this case because it helps determine the cause of the elevated creatinine level, which can be due to kidney dysfunction or other underlying conditions. LDH is an enzyme present in various tissues, including the kidneys, and elevated levels can indicate tissue damage. By measuring LDH levels, healthcare providers can assess the severity and extent of tissue damage and guide appropriate treatment decisions.
Random Sugar
The Random Sugar test is important because it helps in evaluating the blood glucose levels at any time, which is crucial in identifying diabetes or monitoring blood sugar control in diabetic patients. It is especially relevant in this case with a creatinine level of 2.0 mg/dl, as it may indicate impaired kidney function, which can affect glucose metabolism and lead to abnormal blood sugar levels.
What is the relation between creatinine and kidney function?
Creatinine, a chemical that is manufactured within the body without faltering, undergoes complete filtration in the urine by the kidney. Whenever the kidney's functionality is compromised due to various factors, the levels of creatinine escalate. Consequently, creatinine serves as a highly valuable technique to examine the kidney's performance.
Why do doctors ask for GFR if my creatinine level is 2.0?
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.
