<s>[INST] I am a post kidney transplant patient, had a pedia en block in 6/2008 at UCSF.  I haven't had my labs drawn for 8 months. I went yesterday since I've been feeling really exhausted, weak, confused and short of breath.  My hemaglobin is 8 and hematocrit 24, just got the lab results.  Should I be concerned and call my Nephrologist? [/INST] Hi, Your hemoglobin level is very low and that may contribute to severe weakness and fatigue. You can consult your nephrologist and you may require blood transfusions also. Hope I have answered your query. Let me know if I can assist you further. </s>
