Stories
A Quest Health user
Following up on vitamin results
This user ordered Quest panels directly and found a very low vitamin D result. Later nutrient testing helped them track vitamin D and identify a low B12 result, which they took back to their doctor for treatment.

Getting more context for a kidney result
After an unexpectedly low kidney-function estimate, this user ordered Quest’s expanded kidney test with cystatin C. The new estimate was considerably higher, giving them reassuring additional information to bring to their ongoing health decisions.
