High bilirubin levels in a liver function test (LFT) indicate potential liver dysfunction or other underlying health issues. Bilirubin is a yellow pigment produced during the breakdown of red blood cells. When the liver isn’t functioning properly, bilirubin builds up in the blood, leading to jaundice (yellowing of the skin and eyes). Elevated bilirubin may signal conditions such as liver disease, bile duct obstruction, or hemolytic anemia. Treatments focus on addressing the underlying cause, such as improving liver function, treating infections, or removing blockages in the bile duct.

The urea and electrolytes blood test assesses kidney function and electrolyte balance. High urea levels usually indicate impaired kidney function, dehydration, or a high-protein diet, while low levels suggest malnutrition or liver disease. Electrolytes such as sodium, potassium, and chloride are also measured. High electrolyte levels may point to dehydration, kidney issues, or certain medications, while low levels can indicate fluid overload, hormonal imbalances, or acute illness. Regular monitoring of urea and electrolyte levels helps diagnose and manage conditions like kidney disease and electrolyte disturbances, both of which have serious health implications if left untreated.

High serum urea levels, also known as uremia, indicate impaired kidney function or other health conditions affecting your body’s ability to eliminate waste. Urea is a waste product formed in the liver and filtered by the kidneys. When kidneys are not functioning well, urea accumulates in the bloodstream. Common causes include chronic kidney disease (CKD), dehydration, heart failure, or a high-protein diet. Monitoring serum urea levels through regular blood tests is crucial in assessing kidney health and function. If elevated urea levels are detected, it is important to seek medical advice for proper diagnosis and treatment.

High ALT (alanine aminotransferase) levels in the blood can be a sign of liver damage. ALT is an enzyme primarily found in the liver, and elevated levels indicate that liver cells may be injured or inflamed. Potential causes include hepatitis, fatty liver disease, excessive alcohol use, or certain medications. High ALT levels are typically detected through routine blood tests, and treatment depends on the underlying cause. Maintaining liver health involves lifestyle changes such as reducing alcohol consumption, managing weight, and avoiding harmful medications. Regular monitoring and consultation with a healthcare provider are crucial for managing liver health.
