Kidney
& Liver Function Tests in a Bali Full-Body Check-Up
Answer first: Kidney and liver function tests are
standard blood tests in almost every Bali full-body medical check-up.
For the kidneys, the core markers are
creatinine and eGFR (an estimate of how well they
filter), often with urea/BUN and a urine
test. For the liver, the panel usually
includes ALT, AST, ALP, GGT and bilirubin, sometimes
with albumin. These quietly reveal a lot: early kidney strain, fatty
liver, the effects of alcohol or certain medications, and more. They are
screening tests — they flag when an organ is under pressure,
and a doctor interprets any abnormal result and decides what, if
anything, to do next.
Your kidneys and liver are your body’s filtration and processing
plants, and both tend to signal problems silently, without pain, until
they’re advanced. That’s exactly why blood tests are so valuable: they
catch strain early. As the medical advisor for Bali Medical
Checkup, I’ll explain what each marker means in plain English, so
your results feel less like a wall of abbreviations and more like a
readable health snapshot.
Why these organs need
screening
Both organs can be quite damaged before you feel anything. Chronic
kidney disease, for instance, often progresses silently and is
frequently detected only through routine blood and urine testing (U.S.
National Institute of Diabetes and Digestive and Kidney Diseases,
Kidney Disease Basics). Liver conditions such as fatty
liver are similarly common and often symptomless in early stages.
Because early detection opens the door to simple, effective changes,
these panels are a cornerstone of a comprehensive screen — and are
described alongside the other bloods on our what’s included in a
full-body check-up page.
Kidney function tests
explained
Creatinine. A waste product from muscle that healthy
kidneys clear efficiently. A rising creatinine suggests the kidneys
aren’t filtering as well as they should.
eGFR (estimated glomerular filtration rate). A
calculation, based on creatinine, age and other factors, that estimates
your overall kidney filtering capacity. It’s the single most useful
number for grading kidney health.
Urea / BUN (blood urea nitrogen). Another waste
product; interpreted alongside creatinine and hydration status.
Urinalysis. A urine sample checks for protein, blood
or glucose that shouldn’t be there — an early warning of kidney or
metabolic issues that bloods alone can miss.
Liver function tests
explained
ALT and AST (transaminases). Enzymes released when
liver cells are stressed or inflamed. Raised levels are a common,
non-specific sign — often linked to fatty liver, alcohol, or some
medications.
ALP (alkaline phosphatase) and GGT. Enzymes that,
together, help point to whether an issue involves the bile ducts; GGT in
particular can reflect alcohol intake.
Bilirubin. A pigment the liver processes; high
levels can cause jaundice and help characterise a liver picture.
Albumin. A protein the liver makes; it reflects
longer-term liver (and nutritional) function.
If bloods suggest fatty liver, an abdominal
ultrasound is the natural next add-on to look directly at the
organ — covered in our fatty liver
screening and abdominal ultrasound guide.
What can raise these markers
Results are read in context, because several everyday factors move
them:
- Alcohol can raise liver enzymes; our guide on how long to
avoid alcohol before a check-up explains timing so a heavy weekend
doesn’t skew your baseline. - Intense exercise shortly before testing can
transiently raise some markers — see should you
exercise before a check-up. - Certain medications and supplements affect both
organs; disclose everything you take, as covered in our medications to
pause note. - Dehydration can nudge kidney markers, which is one
reason hydration before testing matters.
These panels also anchor our specialty health screening
packages, where metabolic and organ-focused screening is built
around individual risk.
Reading the results — and
the boundary
A single mildly abnormal enzyme or a borderline eGFR is common and
rarely a crisis. What matters is the pattern, the trend over time, and
your overall picture — which is why context and a clear report matter so
much. Our guide on reading your
blood test results walks through these lines calmly.
The screening boundary is important here: these tests detect
strain; they don’t diagnose or treat kidney or liver disease.
If results are clearly abnormal or trending the wrong way, the correct
next step is a proper clinical work-up with your own doctor or a
specialist — not more tests bundled onto a package. We flag the finding,
ensure the report is GP-ready, and hand it back to a treating
physician.
Frequently asked questions
“Do I need to fast for kidney and liver tests?”
They’re usually part of a fasting blood panel, so follow the fasting
instructions in our preparation
guide.
“My liver enzymes are slightly high — is that
serious?” Often not, and frequently reversible (for example
with fatty-liver-related lifestyle change). It’s read in context and may
simply be rechecked. A doctor interprets it.
“Will one big night of drinking ruin my results?” It
can temporarily raise liver markers. Avoiding alcohol for a few days
before testing gives a truer baseline.
“What if something looks wrong while I’m away?”
We’ll provide a clear, GP-ready report so you can follow up at home —
see sharing
results with your GP.
A clear read on two vital
organs
Because your kidneys and liver rarely complain until late, these
simple blood tests are among the most valuable in any screen. Tell us
about your history and lifestyle, and we’ll make sure the right panels —
and any follow-on imaging — are included and clearly explained. The
Sanur Health Concierge team arranges the bloods, ultrasound if needed,
and a report your own doctor can use.
