The cost of a simple routine blood test is usually around$20. However, ordinary routine blood test only includes white blood cells, hemoglobin, and platelets, of which white blood cells include neutrophils, lymphocytes, monocytes, eosinophils, and basophils; hemoglobin includes the determination of average red blood cell volume, average red blood cell hemoglobin content, and average red blood cell hemoglobin concentration. Some hospitals have routine blood tests, along with C-reactive protein and reticulocytes, that is, routine blood tests plus C-reactive protein, or routine blood tests plus reticulocytes, which are relatively more expensive, around$40. If you add blood smear analysis, it may cost a little more.
