• Not all lab appointments will require fasting. Your provider will notify you if you need to fast for your blood test. If you have any other questions, please call us or send a message through the Oshi app.

    The following is a list of labs that will always require fasting:

    • Vitamin K levels
    • Liver Fibrosis testing (ELF, Fibosure, FibroMETER, FibroTEST, Fib-4) 
    • Lipid panel, cholesterol tests 

    If the lab has different fasting recommendations, please follow your provider’s directions or call to clarify instructions. 

  • If you have a fasting lab, you’ll need to fast for at least eight (8) hours before the labs are drawn.

  • No, unfortunately, you cannot eat anything during the fasting period before your labs are drawn.

  • Yes, we definitely encourage you to drink at least two glasses (16 ounces or more) of water in the morning before your fasting labs. Being hydrated will help make sure that there are no issues drawing your blood (and it’ll help fend off those hunger pains). You can also have one cup of unflavored black coffee (no sugar, no milk).
