Vitamin D is essential for a range of biological functions, with its primary role being to regulate calcium and phosphorus levels in the body, which are critical for maintaining bone health. Adequate Vitamin D supports the absorption of calcium in the intestines, helping to form and maintain strong bones. Without sufficient levels, bones can become thin, brittle, or misshapen, leading to conditions like osteoporosis in adults and rickets in children. Beyond bone health, Vitamin D plays a significant role in immune function, helping the body defend against infections and illnesses. Recent research also suggests that Vitamin D may influence mood regulation, cardiovascular health, and the prevention of chronic diseases such as type 2 diabetes​.

Micronutrients are essential vitamins, minerals, amino acids, and antioxidants that the body requires in small amounts but are crucial for a wide range of bodily functions. Unlike macronutrients (carbohydrates, fats, and proteins), which provide energy, micronutrients support vital physiological processes that maintain health and well-being. Although required in minute quantities, micronutrients play a pivotal role in everything from cellular function and metabolism to immune defense and mental clarity.

A urea blood test measures the amount of urea nitrogen in your blood, a waste product produced by the liver during protein metabolism and removed by the kidneys. Elevated urea levels can indicate that the kidneys are not functioning properly, as they are responsible for filtering urea out of the bloodstream. Normal urea levels range from 7 to 20 mg/dL. High levels may signal kidney disease, dehydration, or excessive protein intake, while low levels might point to liver problems. Regular testing is crucial for assessing kidney function and ensuring overall health.

A C-reactive protein (CRP) blood test measures the level of CRP, a substance produced by the liver in response to inflammation. Elevated CRP levels indicate inflammation in the body, which can be caused by infections, chronic diseases like arthritis, or cardiovascular conditions. While normal CRP levels are generally below 3 milligrams per liter (mg/L), higher levels may signal acute inflammation or an increased risk of heart disease. CRP tests are used to assess the severity of inflammation and guide diagnosis and treatment plans, making them crucial for monitoring overall health.
