What is Creatinine?
Serum creatinine is a substance that our bodies naturally produce as a result of a chemical called creatine phosphate found in our muscles. It is made at a steady pace, so the levels of serum creatinine in our blood usually remain consistent. However, the amount of serum creatinine can vary depending on how much muscle we have. Generally, men tend to have higher levels of serum creatinine compared to women because they typically have more muscle mass. On the other hand, during pregnancy, the levels of serum creatinine are usually lower.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps measure the amount of creatinine in your body. Before the test, it's important to inform your doctor about any medications or supplements you are taking, as they might affect the results. On the day of the test, you'll need to visit a lab, where a healthcare professional will draw a small amount of blood from your arm using a needle. The blood sample is then sent to the lab, where they use special equipment to measure the concentration of creatinine in your blood, which helps doctors assess kidney function.
What does a creatinine of 1.4 mg/dl mean in women?
The normal levels of creatinine for women are between 0.55 and 1.02. A creatinine value of 1.4 mg/dl is considered slightly higher than normal. It is recommended to have additional tests, such as creatinine clearance, to evaluate kidney function.3,4
Is creatinine 1.4 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 1.4 in male across different ages
| Age Group | Is Creatinne of 1.4 dangerous? |
|---|---|
| 25yrs - 29 yrs | above normal, not dangerous |
| 29yrs - 95 yrs | significantly high, but not dangerous, needs attention |
Table of danger posed by Creatinine 1.4 in female across different ages
| Age Group | Is Creatinne of 1.4 dangerous? |
|---|---|
| 25yrs - 28 yrs | significantly high, but not dangerous, needs attention |
| 28yrs - 95 yrs | bad, needs attention, could be dangerous, Consult a doctor |
What is the normal range and is a creatinine of 1.4 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 1.4 is considered abnormal.
What could cause a creatinine level of 1.4?
- Dehydration: Dehydration can cause an increase in creatinine level as there is less water available to dilute the waste products in the blood.
- Kidney infection: Infections in the kidneys can lead to inflammation and damage, causing an elevation in creatinine levels.
- Kidney stones: The presence of kidney stones can obstruct the normal flow of urine, leading to an accumulation of waste products like creatinine.
- Urinary tract obstruction: Blockages in the urinary tract can result in impaired kidney function and an increase in creatinine levels.
- Chronic kidney disease: Damage to the kidneys over a long period can cause a gradual increase in creatinine levels.
- High protein diet: Consuming excessive amounts of protein can put extra stress on the kidneys, leading to elevated creatinine levels.
- Certain medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can cause kidney damage and an increase in creatinine levels.
- Muscle breakdown (rhabdomyolysis): Conditions that cause muscle breakdown, like severe trauma or certain genetic disorders, can result in elevated creatinine levels.
- Heart failure: Decreased blood flow to the kidneys due to heart failure can lead to impaired kidney function and an increase in creatinine levels.
- Diabetes: Uncontrolled diabetes can cause damage to the kidneys, leading to an elevation in creatinine levels.
What other tests should be done if creatinine level is 1.4?
Serum Electrolytes
The Serum Electrolytes test is important because it helps evaluate the balance of important electrolytes in the body, such as sodium, potassium, and chloride. Imbalances in these electrolytes can affect kidney function and potentially contribute to elevated creatinine levels, making the test crucial for assessing renal health and guiding appropriate treatment decisions.
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 during protein metabolism. A high blood urea level indicates impaired kidney function and can help diagnose conditions such as kidney disease or dehydration. Therefore, in conjunction with a creatinine test, the blood urea test provides valuable information about kidney health and overall body metabolism.
Estimated GFR
The estimated glomerular filtration rate (eGFR) test is important because it provides an estimate of how well the kidneys are functioning. A creatinine level of 1.4 mg/dl alone does not provide a complete picture of kidney function, as it can be influenced by factors such as age, gender, and muscle mass. The eGFR test takes into account these factors and provides a more accurate assessment of kidney function.
HBA1C
The HbA1C test is important because it provides a measure of long-term glucose control, reflecting average blood sugar levels over a period of 2-3 months. It helps in the diagnosis and monitoring of diabetes, as well as assessing the risk of developing complications associated with high blood sugar levels. In this case, the HbA1C test can help determine if the elevated creatinine level is due to uncontrolled diabetes.
LDH
The LDH (lactate dehydrogenase) test is important in this case because it helps evaluate kidney function. Elevated levels of LDH may indicate kidney damage or impaired kidney function. Therefore, measuring LDH levels alongside creatinine can provide additional information and aid in the diagnosis and monitoring of kidney-related conditions.
Random Sugar
The Random Sugar test is important in this case because it helps evaluate the patient's blood glucose levels at any given time, providing immediate information on their glycemic control. This is crucial as a high random sugar level may indicate uncontrolled diabetes, which can contribute to kidney damage and worsen the creatinine levels. Monitoring and managing blood sugar levels are essential to prevent further complications and maintain kidney health.
What is the relation between creatinine and kidney function?
Creatinine, a chemical naturally generated within the body, maintains a consistent production rate. The kidney diligently sieves out creatinine, eliminating it entirely through urine. However, if the kidney's performance is hindered, be it through various causes, the levels of creatinine escalate. Consequently, creatinine proves to be an exceedingly valuable means of assessing kidney functionality.
Why do doctors ask for GFR if my creatinine level is 1.4?
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.
