Transthyretin (TTR)

On December 27, 2010, in General Nutrition, Tests, by Andrea

Transthyretin (TTR) is the test formally known as prealbumin.  It still is known as prealbumin by some labs, so be aware that the two names may be used interchangeably.

Transthyretin is a transport protein for thyroxine (T4) and retinol (vitamin A).  The main clinical use for a transthyretin level is for monitoring nutritional status as it is a better indicator of protein status than albumin.

This is a non-fasting test.

Range: 20-40 mg/dL Range given are from MY laboratory ranges.  Yours may vary slightly.  Adapt as needed.

A low level indicates malnutrition.
