Albumin is a protein made by the liver, playing a crucial role in maintaining blood volume and pressure. Low albumin levels can indicate liver or kidney disease, inflammation, or malnutrition.

Calcium is essential for bone health, muscle function, nerve transmission, and blood clotting. Abnormal calcium levels may indicate bone disease, kidney disorders, or parathyroid gland problems.

Creatinine is a waste product produced by muscle metabolism and filtered by the kidneys. Measuring creatinine levels helps assess kidney function, as elevated levels may indicate impaired kidney function or disease.

Uric acid is formed when the body breaks down purines, which are found in certain foods. High uric acid levels can lead to gout, kidney stones, and other health issues.

Urea is produced when the liver breaks down proteins, and it is excreted through urine. Elevated urea levels can indicate kidney dysfunction or dehydration.
