LFT and KFT

Liver Function Test (LFT) & Kidney Function Test (KFT) – Detailed Overview

Liver Function Test (LFT) and Kidney Function Test (KFT) are essential blood tests used to assess the health and functionality of the liver and kidneys, respectively. These tests help detect liver diseases, kidney disorders, infections, and other medical conditions.

Liver Function Test (LFT)

What is an LFT?

A Liver Function Test (LFT) is a blood test that measures different enzymes, proteins, and substances produced by the liver to check its health and functioning. It helps diagnose liver diseases, infections, and damage.

Key Parameters in LFT

1. Alanine Aminotransferase (ALT) – Detects liver injury.
2. Aspartate Aminotransferase (AST) – Indicates liver or muscle damage.
3. Alkaline Phosphatase (ALP) – Assesses bile duct health.
4. Bilirubin – Helps detect jaundice and liver dysfunction.
5. Albumin & Total Protein – Evaluates liver’s ability to produce proteins.

Uses of LFT

• Detects liver infections (hepatitis, jaundice).
• Identifies liver damage from alcohol, drugs, or diseases.
• Monitors liver function in chronic conditions.

Kidney Function Test (KFT)

What is a KFT?

A Kidney Function Test (KFT) assesses how well the kidneys filter waste from the blood. It helps diagnose kidney diseases, infections, and disorders affecting kidney function.

Key Parameters in KFT

1. Serum Creatinine – Indicates kidney filtration efficiency.
2. Blood Urea Nitrogen (BUN) – Measures waste removal ability.
3. Estimated Glomerular Filtration Rate (eGFR) – Evaluates kidney function level.

Uses of KFT

• Detects kidney diseases, infections, and damage.
• Assesses chronic kidney disease (CKD) progression.
• Monitors kidney health in patients with diabetes or high blood pressure.

Conclusion

LFT and KFT are crucial tests for diagnosing liver and kidney disorders, ensuring early detection and timely treatment for better health management.
