Kidney Function Profile
Blood Test for Kidney Function and Unexplained Fatigue
What this test measures
Albumin
Hyperalbuminemia is a condition characterized by high levels of albumin in the blood, often seen in dehydration or high protein diet.
Bun/Creatinine Ratio
An elevated BUN to creatinine ratio can also indicate dehydration, as water loss can lead to an increase in blood urea nitrogen levels relative to creatinine.
Calcium
Hypercalcemia is a condition characterized by high levels of calcium in the blood, which could be related to hyperparathyroidism, cancer, or excessive vitamin D intake.
Carbon Dioxide
Metabolic acidosis is a condition characterized by low levels of carbon dioxide in the blood, often seen in conditions like kidney disease, lactic acidosis, or diabetic ketoacidosis.
Chloride
Hyperchloremia is a condition characterized by high levels of chloride in the blood, often seen in conditions like dehydration, renal disease, or metabolic acidosis.
Creatinine
Elevated levels of creatinine in the blood can indicate renal disease as the kidneys are responsible for clearing creatinine from the body.
Glucose
Elevated levels of glucose in the blood can indicate diabetes, a chronic condition where the body cannot regulate blood sugar levels effectively.
Phosphate (As Phosphorus)
Hyperphosphatemia is a condition characterized by high levels of phosphate in the blood, often seen in patients with kidney disease or hypoparathyroidism.
Potassium
Hyperkalemia is a condition characterized by elevated levels of potassium in the blood, which could be indicative of kidney disease as the kidneys are responsible for maintaining potassium balance.
Sodium
Hypernatremia is a condition characterized by high levels of sodium in the blood, which can be caused by dehydration, excessive sodium intake, or conditions that cause the body to lose water.
Urea Nitrogen (Bun)
Low levels of blood urea nitrogen (BUN) can indicate liver disease or malnutrition, as the liver plays a role in urea production.
eGFR
A low eGFR (estimated glomerular filtration rate) can indicate chronic kidney disease, as it suggests the kidneys are not filtering waste from the blood effectively.
