What is Creatinine?
Serum creatinine is a substance that our body produces as a waste product from a chemical called creatine phosphate found in our muscles. It is made at a steady rate, meaning it is consistently produced in our bodies. The amount of serum creatinine in our blood depends on the amount of muscle we have, so it tends to be higher in men compared to women. Interestingly, during pregnancy, the level of serum creatinine is usually lower. So, in simple terms, serum creatinine is a waste product that tells us about our muscle mass and can vary depending on our gender and pregnancy status.1
How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors assess how well our kidneys are functioning. Before the test, it is important to ensure proper pretest preparation. This means staying well-hydrated and avoiding certain medications that could interfere with the results. Once in the lab, a small amount of blood is drawn from our arm using a needle. This blood sample is then sent to a special machine called a spectrophotometer. Inside the spectrophotometer, the blood is mixed with a chemical solution that reacts with creatinine. This reaction creates a color change, and the spectrophotometer measures the intensity of this color. By comparing the color intensity to a standard, the machine can determine the concentration of creatinine in our blood, which helps doctors understand how well our kidneys are working.
Is creatinine 1.3 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 1.3 in male across different ages
| Age Group | Is Creatinne of 1.3 dangerous? |
|---|---|
| 25yrs - 44 yrs | above normal, not dangerous |
| 44yrs - 95 yrs | significantly high, but not dangerous, needs attention |
Table of danger posed by Creatinine 1.3 in female across different ages
| Age Group | Is Creatinne of 1.3 dangerous? |

| 42yrs - 95 yrs | bad, needs attention, could be dangerous, Consult a doctor |
What is the normal range and is a creatinine of 1.3 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 1.3 is considered abnormal.
What could cause a creatinine level of 1.3?
- Dehydration: Dehydration can cause an increase in creatinine levels as it reduces the blood flow to the kidneys.
- Kidney Infection: Infections in the kidneys can lead to inflammation and impairment of kidney function, resulting in elevated creatinine levels.
- Kidney Stones: The presence of kidney stones can obstruct the urinary tract and cause a buildup of creatinine in the blood.
- Urinary Tract Obstruction: Blockages in the urinary tract can prevent the proper excretion of creatinine, leading to its accumulation in the blood.
- Chronic Kidney Disease: Progressive damage to the kidneys over time can result in impaired filtration and increased creatinine levels.
- Acute Kidney Injury: Sudden damage to the kidneys, often caused by conditions like severe infections or medication toxicity, can lead to a rapid rise in creatinine levels.
- High Protein Diet: Consuming excessive amounts of protein can cause an increase in creatinine production, resulting in elevated levels.
- Certain Medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and certain antibiotics, can affect kidney function and lead to elevated creatinine levels.
- Muscle Injury: Significant muscle injury or breakdown, such as rhabdomyolysis, can release large amounts of creatinine into the bloodstream.
- Heart Failure: In cases of severe heart failure, reduced blood flow to the kidneys can impair their function and result in increased creatinine levels.
What other tests should be done if creatinine level is 1.3?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps evaluate 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 elevated creatinine level. Therefore, the Serum Electrolytes test can provide valuable information for diagnosing and managing the underlying condition.
Blood Urea
The Blood Urea test is important because it measures the level of urea nitrogen in the blood, which is a waste product generated by the liver during protein metabolism. Elevated levels of urea can indicate impaired kidney function, as the kidneys are responsible for filtering and excreting urea from the body. Therefore, in conjunction with the creatinine level, the Blood Urea test helps assess kidney health and function.
Estimated GFR
The Estimated Glomerular Filtration Rate (eGFR) test is important for assessing kidney function, particularly in individuals with a creatinine level of 1.3 mg/dl. eGFR provides an estimation of the amount of blood filtered by the kidneys per minute, which helps identify the stage of kidney disease and guides treatment decisions. It is a crucial tool in monitoring renal function and determining the appropriate management for individuals with kidney impairments.
HBA1C
The HbA1c test is important because it provides an average blood sugar level over the past 2-3 months, allowing for the diagnosis and monitoring of diabetes. It is particularly relevant in this case with a creatinine level of 1.3 mg/dl, as it helps assess long-term glucose control and the risk of complications associated with diabetes, such as kidney damage. Monitoring HbA1c levels can guide treatment decisions and interventions to improve glycemic control.
LDH
The LDH test is important because it helps assess tissue damage or injury. In this case, a creatinine level of 1.3 mg/dl suggests potential kidney dysfunction, and LDH can aid in determining the underlying cause, such as renal cell injury. Additionally, LDH levels can help differentiate between different causes of kidney damage, aiding in diagnosis and treatment decisions.
Random Sugar
The Random Sugar test is important because it helps evaluate blood glucose levels at any time of the day, providing valuable information about a person's overall glycemic control. In the case of a creatinine level of 1.3 mg/dl, the Random Sugar test can help assess the patient's risk of developing diabetes or monitor their existing diabetes management. It can also aid in identifying potential kidney dysfunction or disease related to the elevated creatinine level.
What is the relation between creatinine and kidney function?
Creatinine, a chemical synthesized consistently within the body, is entirely expelled in urine via the diligent work of the kidneys. However, when these vital organs experience impairments, for various reasons, creatinine levels surge upwards. Hence, creatinine serves as a supremely valuable means of assessing renal functionality.
Why do doctors ask for GFR if my creatinine level is 1.3?
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.
