Method for detecting antibodies to folic acid
Background
Folate, an essential B-vitamin, is crucial for a variety of health-related functions. The recognition that too few women obtained sufficient folate levels from their diet and knowing that a folate deficiency put embryos at risk for serious birth defects led to mandatory fortification of certain foods to prevent deficiencies. Such preventive...
