Apolipoprotein A-I

The main structural protein of HDL particles, so in effect a count of them.

Unit mg/dLTypical adult range 110–170 mg/dL
What it is

The main structural protein of HDL particles, so in effect a count of them.

Why it matters

It stands to HDL as apolipoprotein B stands to LDL: the number of particles rather than the cholesterol they happen to be carrying.

Reading the number

Here a higher value generally reads better. Its real use is the ratio to apolipoprotein B, which several labs print alongside it.

When to raise it

Worth reading with apolipoprotein B rather than on its own.
