What is Creatinine?
Serum creatinine is a substance that our body makes as a result of the breakdown of creatine phosphate found in our muscles. It is produced at a steady rate, which means it stays pretty consistent in our blood. However, the amount of serum creatinine can vary from person to person depending on their muscle mass. In general, men tend to have higher levels of serum creatinine compared to women because they usually have more muscle. On the other hand, during pregnancy, the levels of serum creatinine are usually lower.1How is creatinine measured?
A serum creatinine lab test is a simple blood test that helps doctors assess how well your kidneys are functioning. Before the test, it is important to avoid eating large amounts of meat, as it can affect the accuracy of the results. On the day of the test, a healthcare professional will draw a small sample of blood from your arm using a needle. This blood sample is then sent to the lab, where they measure the concentration of creatinine in your blood. Creatinine is a waste product produced by the muscles, and its level in the blood can indicate how well your kidneys are filtering it out.What does a creatinine of 7.0 mg/dl mean in men?
A creatinine value of 7.0 mg/dl is very high and can be life-threatening. It is important that you go to the hospital right away and you may need to undergo dialysis. Do not try to treat yourself at home.3,4What does a creatinine of 7.0 mg/dl mean in women?
A normal creatinine level for women is between 0.55 and 1.02. If your creatinine value is 7.0 mg/dl, it is considered very dangerous. It is highly recommended that you go to the hospital right away and you may need dialysis. Do not try to treat yourself.3,4Is creatinine 7.0 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 7.0 in male across different ages
| Age Group | Is Creatinne of 7.0 dangerous? |
|---|---|
| 25yrs - 95 yrs | very dangerous, Get immediate medical advice and treatment. |

What is the normal range and is a creatinine of 7.0 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 7.0 is considered abnormal.What could cause a creatinine level of 7.0?
- Acute Kidney Injury: Sudden damage to the kidneys can lead to a sharp increase in creatinine levels.
- Chronic Kidney Disease: Long-term kidney damage and reduced kidney function can cause elevated creatinine levels.
- Dehydration: Insufficient fluid intake or excessive fluid loss can concentrate creatinine in the blood.
- Urinary Tract Obstruction: Blockages in the urinary tract can hinder the normal flow of urine, leading to elevated creatinine levels.
- Medication Side Effects: Certain medications, such as certain antibiotics or chemotherapy drugs, can increase creatinine levels as a side effect.
- Rhabdomyolysis: Severe muscle injury or breakdown can release myoglobin into the bloodstream, leading to elevated creatinine levels.
- High Protein Diet: Consuming excessive amounts of protein can increase creatinine production and subsequently raise creatinine levels.
- Glomerulonephritis: Inflammation of the glomeruli, the filtering units of the kidneys, can impair kidney function and cause elevated creatinine levels.
- Kidney Infection: Infections affecting the kidneys, such as pyelonephritis, can lead to kidney damage and elevated creatinine levels.
- Polycystic Kidney Disease: A genetic disorder characterized by the growth of numerous cysts in the kidneys, which can impair kidney function and cause elevated creatinine levels.
What other tests should be done if creatinine level is 7.0?
Serum Electrolytes
The Serum Electrolytes test is important in this case because it helps to assess the balance of essential minerals in the body, such as sodium, potassium, and chloride. Abnormal electrolyte levels can indicate kidney dysfunction and can further contribute to complications associated with elevated creatinine levels. Monitoring electrolyte levels is crucial in managing and treating patients with high creatinine levels.Blood Urea
The blood urea test is important because it helps assess kidney function and overall health. Elevated levels of blood urea nitrogen (BUN) indicate impaired kidney function, which can be a result of conditions such as kidney disease or dehydration. Monitoring BUN levels alongside creatinine levels helps provide a more comprehensive assessment of kidney health.Estimated GFR
The Estimated GFR (glomerular filtration rate) test is important in assessing kidney function because it measures how well the kidneys are filtering waste from the blood. A creatinine level of 7.0 mg/dl indicates severe kidney impairment, but the Estimated GFR test provides a more accurate and comprehensive measure of kidney function, helping healthcare professionals determine appropriate treatment plans and monitor disease progression. Therefore, it plays a crucial role in managing kidney diseases and guiding clinical decisions.HBA1C
The HbA1c test is important for individuals with a creatinine level of 7.0 mg/dl as it measures the average blood sugar levels over the past 2-3 months, providing insight into long-term glycemic control. This test helps assess the risk and management of diabetes, guiding treatment decisions and monitoring the effectiveness of interventions. It is crucial in determining the overall blood glucose control in individuals with renal impairment.LDH
The LDH (lactate dehydrogenase) test is important in this scenario as it helps determine the cause of the elevated creatinine level, which could be due to kidney dysfunction or other underlying conditions. LDH is an enzyme found in various tissues, and its levels can indicate tissue damage or cell death. Therefore, the LDH test can provide valuable information about the extent of tissue damage and assist in diagnosing and treating the underlying condition.Random Sugar
The Random Sugar test is important in this case because a high creatinine level suggests impaired kidney function, and elevated blood sugar levels can contribute to kidney damage. Monitoring random sugar levels helps assess the patient's risk for developing or worsening diabetes, which can further impact kidney health. Early detection and management of high blood sugar levels can help prevent or delay kidney complications.What is the relation between creatinine and kidney function?
Creatinine, a chemical generated within the body consistently, undergoes filtration by the kidney, resulting in its complete elimination via urine. Impaired kidney function for various causes leads to an elevation in creatinine levels. Consequently, creatinine serves as an invaluable tool for evaluating the efficiency of the kidney.Why do doctors ask for GFR if my creatinine level is 7.0?
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.What is my GFR if my creatinine level is 7.0?
