“…Of the 15 guidelines that recommended quantification of Hb or a full blood count, only four specified a threshold Hb level indicative of anemia (\ 12 g/ dL [5,51,57] and \ 10 g/dL [50], respectively). Although six of the guidelines recommended evaluating symptoms of ID/IDA/anemia during the initial assessment [50-52, 56, 61, 62], only four of these described the specific signs and symptoms of anemia or ID/IDA to check for in the patient [50,51,56,62]. In these four guidelines, pallor [50,51], shortness of breath with or without activity [50,56], and lightheadedness/dizziness [50,56,62] were the most commonly stated signs and symptoms.…”
