Biochemistry case challenges (Proceedings)

Nov 01, 2009

Biochemical profiles may provide a definitive diagnosis in some cases while in other cases the information is useful mostly in ruling in or ruling out differential diagnoses. A baseline complete biochemical profile may be all that's needed for many patients but additional tests are indicated in some cases.

We will discuss some interesting, challenging cases we've had in which biochemical findings were important in making a diagnosis and in monitoring response to treatment.
