Frequently asked questions

What is the difference between FBS and FCS?

Both are tiers of NCAA Division I college football. FBS (Football Bowl Subdivision) is the higher tier, with bigger budgets, more scholarships and a bowl-game postseason; FCS (Football Championship Subdivision) is the level below it and decides its champion through a bracketed play-off.

What is a normal FBS level?

A fasting blood sugar under 100 mg/dL (5.6 mmol/L) is generally considered normal, 100–125 mg/dL suggests prediabetes, and 126 mg/dL or higher on two occasions usually indicates diabetes. Only a doctor can interpret your result properly.

How long do you have to fast for an FBS test?

Usually eight to twelve hours, with plain water allowed. Most people book the test first thing in the morning so the fast happens overnight.
