The short answer
A provider looking at an abnormal result asks three questions: could this be an artefact or a temporary effect, does it fit the clinical picture, and would acting on it change anything. The answer leads to one of four moves — repeat it, add a targeted test, change something, or record it and follow the trend. Very few abnormal results lead straight to a diagnosis, and that is not delay; it is how false alarms are kept from turning into treatment.
The four possible next steps
Repeat the test
Used for borderline values, surprising values, and anything where a technical problem at the draw is plausible. The repeat interval is chosen deliberately.
Add a specific follow-on test
An abnormal blood count leads to iron studies rather than a scattergun panel; an abnormal TSH leads to a free T4.
Change something
Start, stop or adjust a treatment, or make a targeted lifestyle change — with a date to reassess.
Watch the trend
Some values are best interpreted over time. This is a legitimate plan, provided it is written down with a next date.
Why a flagged result is often nothing
- Reference ranges describe most of a population, so a proportion of healthy people fall outside them.
- Recent illness, exercise, dehydration, a meal or alcohol shift many values temporarily.
- Medications and supplements — biotin especially — interfere with some assays.
- Handling and timing at the collection site affect several tests.
- Ranges differ between laboratories, so comparing across them can mislead.
Results that need attention quickly
A small group of values — severe electrolyte disturbances, very high blood sugar, very low haemoglobin, certain kidney and clotting results — are treated as urgent by the laboratory and reported to the ordering provider immediately. If that applies to you, you will be contacted with an instruction, and following it promptly matters. Independently of any result, the symptoms in the red-flag list above need emergency care.
How to get results handled properly
- Ask, at the moment the test is ordered, how and when you will get the result.
- Ask for a review rather than a portal notification — the explanation is the part that helps.
- Bring previous results so a trend can be seen rather than a snapshot.
- Ask what the result changes. If it changes nothing, ask why it was ordered.
- Keep a copy. Your own record is the most portable medical record you will ever have.
How Presence handles it
Results come back to the ordering provider and are reviewed with you in plain language, with the plan attached and a next date where one is needed. Members have unlimited virtual visits, so a results review is not a reason to hesitate about another appointment. Testing itself is priced before it is ordered — see labs and imaging savings.
This page explains the process. It cannot interpret your result, and it is not a reason to delay care you have been told to seek.
