THE TEACHING CONNECTION

Keep the original result in view

Keep the original result in view

Start with your original report: check the date, units, the lab’s range, and the exact result. On a genetic report, the gene name, variant ID, and your actual genotype mean different things. A lab flag alone is not a diagnosis.

Putting the pieces together

Dr. Purser’s integrated approach asks whether the result aligns with symptoms, other current measurements and the proposed clinical goal. It also keeps trends and collection context visible. Comparing numbers without checking the method, units or timing can create an apparent change that is not a reliable clinical trend.

A question to bring to your visit

What does this test measure, what does it not measure, and which result or symptom would change our next decision?

Reading your own results

Bring your original report, current results, health history, and medicines to your visit. This information can help you ask questions, but it cannot diagnose a condition or choose a supplement dose for you.
