An advanced diagnostic laboratory package for anemia, combining assessment of basic blood functions with specialized tests to identify the underlying causes of anemia. This includes a complete blood count (CBC) with detailed anatomy of red blood cells, assessment of iron stores and metabolism (iron, TIBC), hematopoietic vitamin B12, folic acid, and kidney function tests (creatinine, urea) that may contribute to anemia. It also includes tests to detect hemolytic anemia (uric acid, hemoglobin electrophoresis) and autoimmune diseases (ANA, rheumatoid factor) that may be associated with anemia.
