Could A Cholesterol Test Produce False Results Depending On Previous Days Meals?

I had a grilled ham, turkey, and cheese sandwich with fries for lunch and for dinner I had a 6 oz steak with steamed brocolli, baked sweet potato and cheesecake for dessert. This was on Monday. My fasting cholesterol test was Wednesday morning. Is it possible that this made my results be overstated? I'm only 27 and pretty active so I was surprised to see my cholesterol was high. Total was 226.

Answer

Hi L Keller,

No, your meals on Monday would not affect your lab results on Wednesday. A fasting test (no foods/drinks 8-12 hours prior to labs) gives you the most accurate results. If your labs had been non-fasting then there is the possibility for false highs.

A total cholesterol of 226 is not cause to panic, but a good wake up call to make some changes to lower your levels. Click here to learn more about a diet to lower cholesterol and keep up the physical activity. Also, discuss your results with your MD.
