I have been feeling tired and run down basically since my 2nd baby was born over a year ago and have just had various blood tests. Two have come back as outside normal range: Serum bilirubin - 43 (<21) Serum calcium - 2.09 (2.12-2.51) Is this what has been making me feel rubbish? Has anyone else had the same? My Ferritin and Vitamin D are both within range but look to be at the low end (ferritin 20, range is 10-420 and vitamin D is 55, range said it should be over 50) also my urine came back with high white blood cells and high epithelial cells but negative for bacteria. I was kind of expecting nothing to actually be wrong, or maybe just one thing that could easily be fixed but now I'm worrying there is something wrong with me! Help! (Have name changed for this)
