Blood health
A full blood count looks at the cells that carry oxygen, support immunity and help blood clot.
Full blood count (FBC / CBC)
CoreIncludes haemoglobin, haematocrit, red-cell indices, white-cell count and differential, and platelets.
The Pathhealth
Biomarker Guide.
Understand what common blood tests measure, why they may be useful and when additional testing needs clinical context.
Not a self-ordering menuEvery panel begins with a shared core. Additional tests depend on your intake, age, sex, symptoms, history, medication, risk factors and laboratory availability.
Core
Included in the shared preventative-health foundation.
Generally included in broader Pathhealth panels.
Clinically selected
Added only when the intake or risk profile supports it.
Kidney function & electrolytes
These markers help assess filtration, hydration and the body’s mineral balance.
Creatinine and estimated GFR
CoreUsed together to estimate how effectively the kidneys filter blood.
Urea
CoreProvides additional context about kidney function, hydration and protein metabolism.
Sodium and potassium
CoreKey electrolytes involved in fluid balance, nerves, muscles and heart rhythm.
Chloride and bicarbonate
May add context about electrolyte and acid–base balance when available.
Liver function & proteins
No single test measures every aspect of liver health, so results are interpreted as a pattern.
ALT and AST
CoreEnzymes that may rise when liver or other cells are stressed or injured.
Alkaline phosphatase (ALP)
CoreInterpreted alongside other results when considering the liver, bile ducts and bone.
Bilirubin
CoreA pigment processed by the liver; interpretation depends on the result pattern and clinical context.
Albumin and total protein
CoreProvide context about protein balance, liver synthesis and other health factors.
Gamma-GT (GGT)
Can help interpret liver and bile-duct enzyme patterns.
Glucose & metabolic health
These tests provide complementary views of current and longer-term glucose regulation.
Fasting glucose
CoreA snapshot of blood glucose after an appropriate fasting period.
HbA1c
CoreReflects average glucose exposure over roughly the preceding two to three months.
Uric acid
May be relevant to gout, kidney health and broader metabolic context.
Fasting insulin
Clinically selectedMay occasionally add context, but is not required for routine diabetes screening.
Cholesterol & cardiovascular risk
These markers help build a more complete picture of lipid-related cardiovascular risk.
Total cholesterol, LDL-C, HDL-C and triglycerides
CoreThe standard lipid profile, interpreted together rather than as isolated numbers.
Apolipoprotein B (ApoB)
Reflects the number of atherogenic lipoprotein particles and can refine risk assessment.
Lipoprotein(a) / Lp(a)
A largely inherited risk marker that is generally measured at least once rather than repeatedly.
High-sensitivity CRP (hs-CRP)
A non-specific inflammation marker that may refine cardiovascular risk in selected contexts.
Iron & nutritional markers
These tests are most useful when the intake identifies a relevant symptom, dietary pattern or risk factor.
Ferritin and iron studies
Clinically selectedAssess iron stores and transport using ferritin, iron, transferrin or TIBC, and transferrin saturation.
Vitamin B12 and folate
Clinically selectedMay help investigate anaemia, neurological symptoms, dietary risk or malabsorption.
25-hydroxy vitamin D
Clinically selectedUsed when deficiency risk or a relevant clinical reason is identified; not automatically required for everyone.
Thyroid
Thyroid testing is selected using symptoms, history, medications and risk rather than added automatically.
Thyroid-stimulating hormone (TSH)
Clinically selectedUsually the initial laboratory test when thyroid dysfunction is suspected.
Free T4
Clinically selectedAdds context when TSH is abnormal or the clinical situation warrants it.
Free T3 and thyroid antibodies
Clinically selectedReserved for specific questions rather than routine inclusion in every panel.
Hormonal health
Hormones vary with symptoms, medication, time of day, menstrual stage and other biological factors.
Total testosterone and SHBG
Clinically selectedMay be combined to provide context about androgen status when there is an appropriate indication.
Estradiol, LH and FSH
Clinically selectedCan help answer selected reproductive or endocrine questions when timing and context are recorded.
Prolactin
Clinically selectedUsed for particular symptoms or endocrine questions, not as a universal wellness test.
Urine & risk-based screening
Some useful preventive tests are not blood biomarkers and require specific eligibility or consent.
Urine albumin-to-creatinine ratio
Clinically selectedCan detect small amounts of urinary albumin in people with relevant kidney or cardiovascular risk.
PSA
Clinically selectedRequires an informed, age- and risk-appropriate discussion because potential benefits and harms differ.
HIV or hepatitis screening
Clinically selectedOffered only with appropriate eligibility, explanation and consent.
A longer list is not automatically a better health assessment.
Pathhealth is designed to select useful tests, preserve their laboratory context and turn the results into a clear report. Final test availability and composition are confirmed during coordination.
