DFG
Estimated Glomerular Filtration Rate (DFG) is the most current formula for assessing kidney function. It estimates how well kidneys filter waste from blood based on creatinine, age, sex, and race. Lower DFG values indicate decreased kidney function and potential chronic kidney disease.

Sodium
Sodium is a crucial extracellular cation essential for maintaining fluid balance, nerve function, and muscle contraction. It is often measured through urine biomarkers to assess intake levels.
Potassium
Potassium is an essential mineral and electrolyte that plays a critical role in various bodily functions, including muscle contraction, nerve transmission, and maintaining fluid balance. It helps regulate blood pressure and supports cardiovascular health by counteracting sodium's effects.
Chlorine
Chlorine (chloride) is the major anion in extracellular fluid that maintains acid-base balance, osmotic pressure, and electrical neutrality. It works closely with sodium and is essential for proper hydration and nerve function. Abnormal levels can indicate kidney disease, metabolic disorders, or electrolyte imbalances.
Alkaline reserve (HCO3-)
Alkaline reserve (bicarbonate, HCO3-) measures the blood's buffering capacity against acids. It's crucial for maintaining proper pH balance and reflects kidney function and respiratory status. Abnormal levels can indicate metabolic acidosis, alkalosis, kidney disease, or respiratory disorders.
Urea
Urea is a biomarker produced during the metabolism of proteins and amino acids. It is primarily excreted through urine and serves as an indicator of kidney function. Elevated levels can signal kidney issues, while low levels might indicate liver dysfunction or other metabolic problems. It is commonly referred to as BUN.
Creatinine
Creatinine is a waste product from the normal breakdown of muscle tissue (creatine), which is filtered out by the kidneys. It serves as a key indicator of kidney function, particularly in assessing the glomerular filtration rate (GFR), which measures how well the kidneys are filtering waste from the blood
