This comprehensive preventative and diagnostic laboratory package investigates internal factors affecting skin health and appearance. It focuses on assessing nutritional status by measuring vitamin B12 and zinc, essential for cell regeneration and enzyme function, and evaluating iron stores (ferritin), which impacts skin tone and radiance. The package also includes liver function tests (ALT and AST enzymes) to ensure efficient detoxification of harmful substances that may manifest on the skin, and kidney function tests (creatinine) to confirm fluid and electrolyte balance. A complete blood count (CBC) is performed for a comprehensive assessment.
