For example, this tool could be used for the examination of the anamnesis: the first day of the last menstrual cycle (FDLMC), body mass index (BMI), tetanus (TT) injection; vital signs: blood pressure, pulse, respiration, oxygen levels, fetal heart rate (FHR), and temperature; physical check: mid-upper arm circumference (MUAC), body weight, body height, fetal movement, and Leopold; and supporting examinations: Hemoglobin (Hb) level. This evidence concerns the gene GSTM1 and tetanus.
