Blood results update as promised

Hi @ianf0ster,

As @Rachox has pointed out, LDL usually isn't measured, but calculated on total, HDL and trigs. Most often the Friedewald equation is used, which deducts HDL and trigs (divided by 2.2) from the total. Other formulas exist and might lead to slightly different results (but won't be way off).

However, in @Swiggy 's case the total is 4.5 mmol and HDL is 4.1 mmol, leaving a maximum of 0.4 mmol for LDL, no matter which formula is used. The number reported for LDL was 3.1 mmol, though, so it's way off. Possibly someone at the lab or at the GP's practice entered the data incorrectly. For example, if HDL in fact had been 1.1 mmol (instead of 4.1), the other numbers would work out. Unfortunately, there is no way of really knowing.

The actually happened to me at once too when LDL was given as 148 mg/dl instead of 138 mg/dl -- a typo easily made.
