  • CBC
  • CMP (requires fasting)
  • Lipid Profile (requires fasting)
  • Iron Profile
  • Folate
  • Ferritin
  • TSH
  • HGbA1c
  • Vitamin B12
  • Vitamin B1 (Thiamine Level, Frozen Specimen, Needs to be protected from light)
  • H. Pylori, Urea Breath Test

It is recommended these labs are drawn prior to your initial consultation. Please note these labs are not to be confused with pre admission testing.
