Know Your Numbers.
Understand What They Mean.
Tests are useful when they change a decision. I pair diagnostics with physician interpretation so the output becomes a plan, a caveat, or a reason not to chase the metric.
Every test includes a dedicated consultation with Dr. Hillary Lin to review what is actionable, what is noise, and what needs follow-up before anyone adds another supplement.
Genomics
Your sequence rarely tells you what to do by itself. It is useful when it changes screening, medication choices, or family-risk conversations.
Biological Age
Aging clocks can be useful, but only if they lead to better decisions. I treat them as a trend signal, not a verdict.
Cardiac Health
Cardiac imaging is not for everyone. In the right patient, it can make risk visible before symptoms do.
Metabolic Health
Glucose problems usually show up in the pattern before the diagnosis. CGM and labs help find that pattern.
Fitness & Body Composition
Muscle, bone, aerobic capacity, and visceral fat say more than weight does. Measure them if the result will change training or treatment.

A number is not a protocol.
Direct-to-consumer testing has made it easier to buy data. Buying judgment is harder.
When I review results, I am not reading from a reference-range script. I am asking whether the number fits your history, symptoms, medications, family risk, and trajectory.
Sometimes the answer is a protocol. Sometimes it is a repeat test, a referral, or doing nothing. That restraint is part of the medicine.
Need more than one test?
Individual tests can answer narrow questions. For a care program that connects labs, symptoms, medications, and follow-up over time, explore Dr. Lin's practice.

Tests are ordered or interpreted by Hillary Lin, MD. Partner labs and testing companies are independent entities.
All consultations are provided via telemedicine.
