NABL & ICMRAccreditedThe Kidney Function test (KFT) measures how well your kidneys eliminate waste from the body to evaluate the effectiveness of your kidneys. This test examines various blood parameters, assisting in the diagnosis of kidney diseases, monitoring disease progression, and assessing the impact of medications on kidney function.
The kidneys' roles include detoxifying the body, managing fluid and mineral balance, producing vitamin D, and generating hormones like renin for blood pressure management and erythropoietin for red blood cell formation. Given these critical functions, maintaining healthy kidneys is essential for your health.
Early kidney disease often shows no symptoms, making KFTs essential for everyone. These tests help in the early detection and management of kidney problems. For those in Gurgaon who have diabetes, high blood pressure, heart disease, or a family history of renal disease, regular KFTs are especially critical. Therefore, by ordering a KFT in Gurgaon, people may ensure that their kidneys are functioning properly, which is critical for overall wellness.
A KFT gives a detailed analysis of kidney health and electrolyte status. Test parameters include:
This nitrogen-containing substance is produced from protein metabolism in the liver and excreted by the kidneys. High blood urea levels suggest that the kidneys are not removing it efficiently, which may indicate high protein consumption, kidney damage, or failure.
A waste product from the breakdown of purines, uric acid is excreted through the kidneys. Elevated uric acid levels can occur in kidney tubule damage, gout, certain cancers, or with diets high in animal products and alcohol. Chronic kidney disease usually results in decreased uric acid levels.
A byproduct of protein breakdown that is excreted by the kidneys. Elevated BUN levels may reflect underlying kidney disease.
Produced during the metabolism of muscles, creatinine is filtered by the kidneys. High blood creatinine levels may indicate decreased kidney function or other factors like a high protein intake or substantial muscle mass.
Using creatinine as a reference, eGFR gauges the filtration rate of kidneys, recognised as the most dependable measure of kidney function and essential for diagnosing kidney diseases.
This ratio is a key diagnostic tool for kidney disorders and catabolism, commonly elevated in kidney diseases and conditions like critical illness or upper gastrointestinal bleeding.
The KFT includes a comprehensive electrolyte panel, important for assessing blood mineral levels regulated by the kidneys, such as Calcium, Potassium, Sodium, Chloride, and Phosphorus, to evaluate overall mineral balance and detect potential kidney, lung, or heart issues.
To ensure accurate results from a Kidney test at home, it is important to be well-prepared. Consider the following:
Prerequisites
No special preparation is required but follow any specific guiGRLines from your doctor. For KFT with electrolytes, you may need to stay well-hydrated and refrain from using nicotine.
Best Time to Get Tested
The test does not require fasting, so it can be done at any convenient time during the day.
Who Should Get a Kidney Function Test
Suggested for those who have indications of kidney diseases, chronic illnesses including diabetes or hypertension, or a family history of kidney disease.
Cautions Before Taking Kidney Function Test
Inform your doctor about any medications or antibiotics you are currently taking, as these may need to be paused to ensure accurate test results.
A doctor may request a KFT for several reasons listed below:
Symptoms of Kidney Diseases
A KFT is recommended for symptoms of kidney diseases such as:
Difficulty urinating
Painful/frequent urination
Blood in your urine
These may indicate kidney disease and enable early intervention.
Electrolyte Balance
KFTs are essential for assessing kidney health and ensuring the balance of calcium, sodium, potassium, and other such minerals in the body.
Health Conditions
Diabetes and high blood pressure are known to compromise kidney function. KFTs are particularly important in such cases, as they offer a way to monitor this effect. The information gleaned from these tests helps guide treatment decisions and ensure optimal kidney health.
Assessment of Disease Progression
KFTs are useful in evaluating the progression of kidney disease over time, helping to adjust treatment plans accordingly.
Monitoring Treatment
KFTs track how well kidneys respond to treatments for various health conditions.
The normal ranges for different test parameters and the conditions that can cause deviations are given below:
| Test Parameters | Normal Range | Conditions associated with abnormal levels |
|---|---|---|
| Urea | 19-43 mg/dL (Newborn: 6.5-25.5) | High urea and BUN levels are suggestive of poor kidney function due to acute or chronic kidney diseases, decreased blood flow to the kidneys as in congestive heart failure, shock, stress, recent heart attack or severe burns, bleeding from the gastrointestinal tract, conditions that obstruct urine flow or dehydration. Low urea and BUN levels are uncommon and are not usually a cause for concern. Although they are not used to detect or track severe liver disease or malnutrition, they can be observed in these circumstances. Normal pregnancy also exhibits low urea levels. |
| Blood Urea Nitrogen (BUN) | 6-20mg/dL | |
| Creatinine | 0.66-1.25mg/dL | Creatinine is elevated in kidney damage, infection, urinary tract obstruction, diabetic complications, congestive heart failure, and reduced blood flow to kidneys due to shock. |
| Uric Acid | 3.5-8.5mg/dL | High levels of uric acid are seen in kidney disease, pre-eclampsia, purine-rich food, alcoholism, and side effects of cancer treatment. |
| eGFR | Normal >= 90 Mild decrease 60-89 Mild-moderate decrease 45-59 Severe decrease 15-29 End-stage kidney disease < 15 All values in ml/min/1.73m² | GFR is an important parameter for detecting chronic kidney disease. |
| BUN/creatinine ratio | 10-20 | High BUN/creatinine ratio suggests kidney injury or loss of muscle mass in a critical illness. |
| Sodium | 137 to 145 mmol/L | Sodium levels can increase during dehydration, a disorder of the adrenal glands, kidney disease, and diabetes insipidus. Low sodium levels are caused by diarrhoea, vomiting, kidney disease, liver failure, Addison’s disease, and malnutrition. |
| Potassium | 3.5 to 5.5 mmol/L | High levels may be due to kidney failure, hypoaldosteronism, metabolic or respiratory acidosis. Low levels may be due to diarrhoea, vomiting, hyperaldosteronism, and the use of diuretics. |
| Calcium | 8.4 to 10.2 mg/dL | Low calcium levels may be due to hypoparathyroidism, kidney failure, pancreatitis, malnutrition, or a disorder in calcium absorption. High calcium levels may be due to hyperparathyroidism, hyperthyroidism, sarcoidosis, drugs like diuretics, and excessive calcium supplementation. |
| Phosphorus | 2.5 to 4.5 mg/dL | Low phosphorus levels may be used for malnutrition, vitamin D deficiency, overactive parathyroid glands, and severe burns. High phosphorus levels may be seen during impaired kidney function, hypothyroidism, liver disease, and diabetic ketoacidosis (a complication of diabetes) |
| Chloride | 98 to 107 mmol/L | High levels may be due to diarrhoea, Addison's disease, metabolic acidosis, respiratory alkalosis, and renal tubular acidosis. Low levels may be due to burns, CHF, metabolic alkalosis, vomiting, dehydration, respiratory acidosis (compensated) |
