I m a 34 yo, Female that just got blood work back and it showed three things off, CO2 = 21(L), Anion Gap = 20 (H), & EGFR = 57 (L). I don t have a follow up for two weeks, but am still very fatigued, get out of breath easily, and have palpitations and I m unsure if I should ask for more testing to be done before my next appt or if I just need to wait until the appt.
