Strong

Strong evidence 11 of 48

Outcome data from randomised trials or large prospective cohorts, plus a guideline that actually recommends the test.

  • Strong Standard Lipid Panel (Total Cholesterol, LDL-C, HDL-C, Triglycerides)Blood PanelsThe oldest test on this page and still the one that earns its place most easily. S$20–40 Subsidised for eligible Singaporeans 40+ under Healthier SG Screening (S$0–5 per visit incl. consult).
  • Strong Apolipoprotein B (ApoB)Blood PanelsOne apolipoprotein B molecule sits on every atherogenic lipoprotein particle — LDL, VLDL, IDL and Lp(a) alike &mdash… S$40–70 (add-on to lipid panel)Price guide →
  • Strong HbA1cBlood PanelsGlycated haemoglobin reflects average blood glucose across roughly the preceding two to three months… S$15–25. Diabetes screening is subsidised for eligible Singaporeans 40+ under Healthier SG Screening, which uses a fasting glucose test (S$0–5 per visit incl. consult).
  • Strong Kidney Function Panel (Creatinine/eGFR, Urea, Electrolytes)Blood PanelsCreatinine — used to estimate glomerular filtration rate — together with urea, sodium and potassium. S$15–25. Not part of Healthier SG Screening, which subsidises glucose, lipid, blood pressure and BMI checks only.
  • Strong Complete Blood Count (CBC/FBC)Blood PanelsRed cells, white cells, platelets and their subtypes and indices — the most frequently ordered blood test in medicine… S$10–20. Not part of Healthier SG Screening, which subsidises glucose, lipid, blood pressure and BMI checks only.
  • Strong Urine Albumin-to-Creatinine Ratio (uACR)Blood PanelsA urine test, not a blood test, and the one most often missing from a premium panel that already contains forty blood markers. S$15–30
  • Strong Hepatitis B Screening (HBsAg)Blood PanelsA test whose risk calculus is genuinely different in Singapore from the countries most longevity content is written for. S$20–45 (HBsAg alone; a full hepatitis panel costs more)
  • Strong HIV ScreeningBlood PanelsRoutinely bundled into executive screening packages, and one of the very few items in that bundle carrying an unambiguous population-level recommendation. S$25–60
  • Strong Coronary Artery Calcium (CAC) ScoreScans & ImagingA non-contrast CT that quantifies calcified plaque in the coronary arteries and reports it as an Agatston score. S$300–550Price guide →
  • Strong Faecal Immunochemical Test (FIT)Cancer & Disease ScreeningA stool sample, collected at home, tested for blood invisible to the eye. S$10–30 standalone; subsidised for eligible citizens and PRs under Singapore's national Screen for Life programmePrice guide →
  • Strong Screening MammographyCancer & Disease ScreeningOffered as one of the “choose two” imaging options in most women's executive packages, which badly understates it. S$100–250 standalone; subsidised for eligible women under Singapore's Screen for Life programme
Moderate

Moderate evidence 16 of 48

Consistent association with hard outcomes, but thinner evidence that acting on the result changes them. Reasonable in the right patient, hard to justify as a blanket screen.

  • Moderate Lipoprotein(a) — Lp(a)Blood PanelsAn LDL-like particle carrying an additional apolipoprotein(a) component. S$50–100 (standalone draw S$50–55; more within a bundled specialist package) — full price comparisonPrice guide →
  • Moderate hs-CRP (high-sensitivity C-reactive protein)Blood PanelsA marker of low-grade systemic inflammation, and one of the more honestly contested numbers in preventive cardiology. S$35–40 (standalone draw; more within a bundled specialist package) — full cost breakdownPrice guide →
  • Moderate FerritinBlood PanelsFerritin is the body’s iron storage protein and, inconveniently, an acute-phase reactant that rises with inflammation regardless of iron status. S$30–52 depending on standalone vs. bundled iron-studies panel — full cost breakdownPrice guide →
  • Moderate Testosterone (total, men)Blood PanelsSerum total testosterone, ideally drawn fasting in the morning and confirmed on a second sample if the first comes back low. S$30.60–38.15 (total); S$125–147.15 for combined/free testosterone panelsPrice guide →
  • Moderate Thyroid Function (TSH, fT4)Blood PanelsTSH does the primary screening, with free T4 added once TSH returns abnormal. S$30–45 (TSH or TSH+FT4); S$95–110+ for antibody-inclusive panels — full cost breakdownPrice guide →
  • Moderate Liver Function Panel (ALT, AST, ALP, GGT, Bilirubin)Blood PanelsLiver enzymes and bilirubin, screening for hepatocellular injury through ALT and AST and for cholestasis through ALP, GGT and bilirubin. S$20–35. Not part of Healthier SG Screening, which subsidises glucose, lipid, blood pressure and BMI checks only.
  • Moderate Vitamin B12 / FolateBlood PanelsBoth are required for DNA synthesis and neurological function, and deficiency in either produces macrocytic anaemia and, if it runs long enough… S$30–50 combined
  • Moderate Omega-3 IndexBlood PanelsThe EPA and DHA content of red blood cell membranes, expressed as a percentage of total fatty acids. S$90–140 (specialised assay; fewer local labs offer it)
  • Moderate Cystatin CBlood PanelsA second way of estimating kidney filtration, using a protein whose blood level does not depend on how much muscle you carry. S$40–70
  • Moderate Helicobacter pylori TestingBlood PanelsA bacterium that colonises the stomach lining, causes most peptic ulcers, and is classified as a Group 1 carcinogen for gastric cancer. S$30–60 (IgG serology); S$120–200 (urea breath test)
  • Moderate DEXA — Bone Density & Body CompositionScans & ImagingOne machine sold for two quite different purposes, which is the source of most of the confusion around it. S$140–310 (bone density from S$141.70; body composition from S$308.47)Price guide →
  • Moderate Cardiac CT / Cardiac MRI (beyond calcium scoring)Scans & ImagingCoronary CT angiography uses contrast to visualise the coronary lumen along with both calcified and non-calcified “soft” plaque… S$1,200–2,200 (CCTA); cardiac MRI often higher
  • Moderate Prostate-Specific Antigen (PSA)Cancer & Disease ScreeningThe most argued-about blood test in preventive medicine, and the argument is not resolvable by picking a side. S$30–60Price guide →
  • Moderate EBV Testing for Nasopharyngeal CancerCancer & Disease ScreeningA test whose value depends almost entirely on where you live and whose ancestry you have. S$40–90 (IgA serology); plasma EBV DNA testing is less widely offered and costs more
  • Moderate VO2 Max (Cardiopulmonary Exercise Testing)Emerging & OverhypedA mask, a bike or treadmill, and a graded test to exhaustion measuring how much oxygen you can actually use. S$250–600
  • Moderate Grip StrengthEmerging & OverhypedA hand dynamometer, ten seconds, and a number that predicts death better than systolic blood pressure does. S$0–40 (usually included; a home dynamometer costs less than most single blood tests)
Weak

Weak evidence 18 of 48

Either the association is inconsistent, or it holds but no intervention has been shown to improve outcomes by treating the number.

  • Weak Fasting Insulin / HOMA-IRBlood PanelsFasting insulin and glucose combined into a single index — fasting insulin × fasting glucose ÷ 22.5 — as an estimate of insulin resistance. S$40–60
  • Weak Vitamin D (25-OH-D)Blood PanelsSerum 25-hydroxyvitamin D is the standard measure of vitamin D status, and its role in calcium and bone metabolism is not in dispute. S$120–135 (standalone test, 3 providers, 2026); bundled deficiency panels run S$161–264Price guide →
  • Weak Uric AcidBlood PanelsSerum urate, the end product of purine metabolism, and an unusually clean example of a test that is definitive for one condition and speculative for everything else. S$15–25. Not part of Healthier SG Screening, which subsidises glucose, lipid, blood pressure and BMI checks only.
  • Weak HomocysteineBlood PanelsA sulfur amino acid intermediate in methionine metabolism, raised by B12, folate or B6 deficiency and by polymorphisms such as MTHFR. S$40–60
  • Weak GGT (Gamma-Glutamyl Transferase)Blood PanelsA liver and biliary enzyme that already sits inside most standard liver panels, sensitive to alcohol intake and hepatic oxidative stress. Usually included in liver panels (~S$10–15 standalone)
  • Weak Older Inflammatory Markers (ESR, Fibrinogen, Lp-PLA2)Blood PanelsThree inflammation-adjacent markers that appear on expanded cardiac panels, almost always alongside hs-CRP. S$30–90 depending on how many are bundled
  • Weak Food “Intolerance” IgG PanelsBlood PanelsA large panel — typically 100 to 200 foods — reporting IgG antibodies against each one, sold as a way to find the foods behind bloating, fatigue or brain fog. S$300–800
  • Weak Carotid Ultrasound (Intima-Media Thickness / Plaque)Scans & ImagingUltrasound assessment of carotid artery wall thickness and any plaque, frequently marketed as a “vascular age” or stroke-risk test. S$150–300
  • Weak Abdominal MRI (Visceral Fat / Organ Screening)Scans & ImagingA full abdominal MRI, sold in some longevity packages as a way to image visceral fat directly and screen abdominal and pelvic organs for incidental disease. S$900–1,800
  • Weak Brain MRIScans & ImagingStructural brain imaging, marketed in some executive-health packages as an early screen for silent stroke, aneurysm or neurodegeneration. S$900–1,800
  • Weak Screening Chest X-rayScans & ImagingIncluded in nearly every executive health package in Singapore, and one of the clearest examples of a test that survives because it is traditional rather than because it… S$40–90 (usually absorbed into the package price)
  • Weak Resting ECG (as a Screening Test)Scans & ImagingTwelve leads, five minutes, and a reassuring strip of paper at the end. S$40–80 (usually absorbed into the package price)
  • Weak Thyroid UltrasoundScans & ImagingAn add-on scan offered in most Singapore executive packages, usually as one of a “choose two ultrasounds” option. S$120–250 (or “free” as one of two package ultrasound choices)
  • Weak Tumour Marker Panel (CEA, AFP, CA 19-9, CA 125, CA 15-3)Cancer & Disease ScreeningThe most misleading line on a Singapore executive health invoice. S$150–400 for a five- to seven-marker panel
  • Weak Tonometry (Glaucoma Screening)Cancer & Disease ScreeningThe puff-of-air test, included in most executive packages as a “glaucoma screen”. S$20–50 (usually absorbed into the package price)
  • Weak (for general screening) APOE Genotype TestingEmerging & OverhypedGenotyping the APOE gene, which has three common alleles (ε2, ε3, ε4). S$200–400
  • Weak Gut Microbiome TestingEmerging & OverhypedStool-based sequencing — 16S rRNA or shotgun metagenomics &mdash… S$300–600 (commercial direct-to-consumer)
  • Weak (as a bundle) Bundled "Longevity Panels" / Executive Health PackagesEmerging & OverhypedPre-packaged bundles combining dozens of the tests above, typically mixing genuinely Strong ones — CBC, lipids, HbA1c &mdash… S$3,000–15,000+ depending on packagePrice guide →
Emerging

Emerging evidence 3 of 48

Biologically interesting, commercially available, and not yet validated against hard outcomes. Buy it as an experiment, not a clinical decision.

  • Emerging Multi-Cancer Early Detection Blood TestsCancer & Disease ScreeningA single blood draw claiming to detect dozens of cancers by reading fragments of tumour DNA shed into the bloodstream… S$1,200–2,500
  • Emerging Epigenetic Clocks ("Biological Age" Tests)Emerging & OverhypedDNA methylation patterns at specific genomic sites, combined by algorithm into an estimate of “biological age.” The best-known versions &mdash… S$400–700 (commercial "biological age" tests)
  • Emerging Continuous Glucose Monitoring in People Without DiabetesEmerging & OverhypedA sensor worn on the arm for two weeks, streaming glucose readings to a phone. S$150–400 per 14-day sensor, more with a coaching programme

A note on how to read this. A weak grade is a statement about the published evidence for screening an asymptomatic adult — not a claim that the test is useless. Several weak-graded tests are entirely appropriate when there is a specific clinical reason to order them. What the grade rules out is buying them speculatively, in a bundle, hoping a number will turn out to be actionable.
