I felt the experience was customized and the process was supportive. I loved the chill playlist, the specific suggestions of drinking 32oz before the blood draw. I appreciated the honesty and the ease to reschedule/repeat a blood draw due to a sample or transit issue. Having these biomarkers measured gives me peace of mind. Having a thorough list of benchmarks with optimal ranges not just suggested ones in invaluable. One inconsistency is the various Quest Diagnostic Centers- some are well kept, others are not.
