Short answer: A medical check-up report compares
each of your results against a reference range — the
values typical for a healthy population. A result inside the range is
flagged normal; one outside is flagged high or low, but a single
out-of-range number rarely means something is wrong on its own. What
matters is the pattern, the size of the deviation, and
how it fits your age, symptoms and history. This guide translates the
most common sections of a Bali check-up report — blood count,
cholesterol, blood sugar, liver and kidney — into plain English, and
shows you exactly when an “abnormal” flag deserves a doctor’s attention
rather than a panic.
We’re an independent guide, not your treating clinic — we help you
understand what you’re looking at, then always confirm any concern with
a physician. If you’d like help arranging a review of your results, our
free JHG Medical Concierge can point
you to an English-speaking doctor. Start at the MedicalCheckupBali homepage.
First, understand the
reference range
Almost every line on a lab report shows three things: your
result, the unit, and the
reference range (sometimes called the normal range).
The lab flags your value as normal, “H” (high) or “L” (low) by comparing
it to that range.
Two things surprise people:
- Reference ranges are set so that about 5% of perfectly
healthy people fall outside them. So a mild flag on one test,
in isolation, is common and often meaningless. - Ranges differ slightly between labs. Never compare
a raw number from one clinic to a range printed by another — read each
result against its own lab’s range.
Understanding what each test is measuring helps enormously; our every-test-explained pillar breaks down
what a Bali check-up actually includes, test by test.
The full blood count (FBC /
CBC)
This measures your blood cells. The lines people ask about most:
- Haemoglobin (Hb): carries oxygen. Low can suggest
anaemia (common causes: iron deficiency, blood loss); very high is less
common. - White cell count (WBC): your immune cells. High can
indicate infection or inflammation; low can follow certain infections or
medications. - Platelets: help clotting. In Bali, a low
platelet count on a report — especially with fever — can be an early
clue to dengue, which is why doctors watch it closely after tropical
fevers.
A mildly abnormal FBC after a recent cold is usually nothing; a
markedly abnormal one, or one with symptoms, warrants review.
Cholesterol and the lipid
panel
Your lipid panel usually lists total cholesterol, LDL (“bad”), HDL
(“good”), and triglycerides.
- LDL cholesterol: lower is generally better for
heart health. - HDL cholesterol: higher is generally
protective. - Triglycerides: often rise with diet, alcohol, and —
importantly — if you didn’t fast before the test.
This is where fasting matters: a non-fasting sample can inflate
triglycerides and distort the picture. If your lipids look surprisingly
high, check whether you were told to fast. Our guide on fasting before a blood test covers the prep
that keeps these numbers honest.
Blood sugar and HbA1c
- Fasting glucose: your blood sugar after not eating;
used to screen for diabetes. - HbA1c: your average blood sugar over roughly three
months — a more stable picture than a single glucose reading.
An elevated fasting glucose or HbA1c is one of the more meaningful
flags on a screening report and deserves a doctor’s interpretation,
because it can signal prediabetes or diabetes that benefits from early
action.
Liver and kidney panels
- Liver (ALT, AST, GGT, bilirubin): mildly raised
liver enzymes are common and can follow alcohol, some medications, fatty
liver, or a recent viral illness. Persistent or marked elevations need
investigation. - Kidney (creatinine, urea, eGFR): eGFR estimates how
well your kidneys filter. A one-off borderline value can reflect
dehydration (easy to do in Bali’s heat) rather than kidney disease;
trends over time matter more than a single reading.
| Report section | What it screens | Common benign cause of a mild flag |
|---|---|---|
| Full blood count | Anaemia, infection, dengue clue | Recent minor illness |
| Lipid panel | Heart-disease risk | Not fasting before the test |
| Glucose / HbA1c | Diabetes risk | Recent large meal (glucose only) |
| Liver enzymes | Liver stress | Alcohol, medication, dehydration |
| Kidney (eGFR) | Kidney filtration | Dehydration |
General educational summary only — your report must be
interpreted by a doctor in the context of your health.
When an “abnormal” flag
actually matters
As a rule of thumb, take a flagged result more seriously when:
- It’s markedly outside the range, not just a whisker
over. - Several related tests point the same way (a
pattern, not a lone outlier). - It matches a symptom you actually have.
- It persists on a repeat test.
- It’s a high-stakes marker — blood sugar/HbA1c,
kidney function, or a very abnormal blood count.
Conversely, a single mild flag, no symptoms, and everything else
normal is usually a “note it and recheck” situation, not an
emergency.

education only and is not medical advice or a diagnosis. Laboratory
results must be interpreted by a licensed physician who knows your full

Why a doctor’s
interpretation is non-negotiable
The World Health Organization emphasises that laboratory testing is
only useful when results are interpreted within a proper clinical
context — the same number can be reassuring in one person and important
in another (World Health Organization, guidance on laboratory quality
and use of test results, who.int). That’s exactly why we never encourage
self-diagnosis from a printout. A ten-minute review with an
English-speaking doctor turns a confusing sheet of numbers into a clear
plan.
