• Liver Function Tests (LFTs): Assess liver health and detect liver diseases.
• Kidney Function Tests: Measure filtration efficiency and detect kidney disorders.
• Thyroid Function Tests: Check thyroid hormone levels for imbalances.
• Coagulation Tests: Evaluate blood clotting for conditions like hemophilia.
• Infectious Disease Tests: Detect antibodies or pathogens for infections like HIV or hepatitis.
