- People with fatigue, weakness, fever, bruising, bleeding or recurrent infections
- Anyone whose clinician is monitoring a condition or medication that can affect blood cells
- A broad baseline when symptoms or medical history make it useful

TEST PASSPORT · REVIEWED JULY 2026
Complete blood count
The first look at red cells, white cells and platelets.A CBC can surface patterns consistent with anemia, infection, inflammation or platelet problems. It is a context test: an out-of-range cell count is a clue, not a diagnosis.

HOW TO USE THIS PAGE
Decide whether this test deserves a place in your plan.
- 01Confirm the question
Be clear about what decision the result would change before ordering.
- 02Check fit and preparation
Review who it helps, who should pause and how to protect the quality of the signal.
- 03Plan the response
Know what you will do with a normal, abnormal or unclear result.
01 / WHO SHOULD TAKE IT
Fit the test to
the person.
Testing is useful when the result can change a real decision. These are educational selection criteria, not a diagnosis or personal order.- Repeated wellness testing without a decision attached
- Using one small flag to self-diagnose iron deficiency, infection or cancer
02 / SIGNAL VS. STORY
What it tells you.
What it cannot.
01
Hemoglobin, hematocrit and red-cell size patterns
02
Total and differential white-cell counts
03
Platelet count and indices
01
It does not identify the cause of an abnormal count by itself
02
Hydration, altitude, pregnancy, recent illness and medications can shift results
03
Reference intervals vary by laboratory and population
03 / MARKERS + RANGES
Read the panel
without chasing flags.
The report should show its own method, units and laboratory reference interval. Clinical decision thresholds may be different from a lab interval. We do not invent a universal “optimal” range where authoritative guidance does not support one.Use the laboratory unit and method, then interpret with symptoms, trend and the decision this marker can change.

MEN, WOMEN + LIFE-STAGE CONTEXT
The correct range is personal context—not pink versus blue numbers.
Where biology differs, we call it out. Clinical interpretation should also reflect organs present, hormone therapy, pregnancy, age, medications and health history.
Menstrual blood loss and pregnancy commonly change hemoglobin and hematocrit context; heavy periods can justify iron studies.
Persistently low hemoglobin warrants evaluation; testosterone therapy can raise hematocrit and needs clinician monitoring.
04 / PREPARATION
Protect the quality
of the signal.
The best assay cannot rescue the wrong timing, wrong specimen or wrong question. Follow the ordering clinician and laboratory instructions when they differ from this general guide.Usually not required unless bundled with fasting tests.
Report recent infection, heavy exercise, altitude exposure, pregnancy and relevant medicines.
Compare with symptoms, prior CBCs and follow-up tests—not a generic ‘optimal’ range.
REPEAT CADENCEOnce when clinically indicated, then only at an interval tied to the finding, condition or medication being monitored.
05 / AFTER THE RESULT
Turn the number
into a next step.
- 01
Trend the pattern against previous results
- 02
Add ferritin, B12/folate, reticulocytes or other tests only when the pattern supports it
- 03
Escalate marked abnormalities or symptoms to a clinician
DO NOT WAIT ON A CONSUMER TEST
Shortness of breath, chest pain, fainting or severe weakness
Uncontrolled bleeding or widespread unexplained bruising
Very high fever or signs of serious infection
