PathWest Results Explained
How to read and understand a PathWest blood test report — Western Australia's government-operated public pathology service, covering Perth metropolitan hospitals, regional WA and remote community health.
The Quick Answer
PathWest is Western Australia's public pathology service, operated by WA Health (the Western Australian Government). PathWest is the largest pathology provider in WA, serving all major public hospitals in Perth and regional and remote WA communities.
PathWest also accepts GP-referred community collections at many sites, alongside the private providers Western Diagnostic Pathology and Clinipath. Hospital inpatient results integrate with the WAVE (WA Viewer of Electronic Results) clinical system. Patient access is via the PathWest patient portal and My Health Record.
How a PathWest Report Is Laid Out
PathWest reports use a WA Health government-styled format. Hospital and community reports share the same core structure, though hospital reports include ward and MRN details not present on community collections.
Header
PathWest name and WA Health logo, laboratory address (typically QEII Medical Centre, Nedlands for most reference testing), NATA accreditation number and contact details.
Patient demographics
Full name, date of birth, sex, Medicare number and hospital MRN or UR number (for hospital collections) or episode number (for community collections). Always verify these match you.
Ward or GP details
For hospital samples: ward name, bed number and treating consultant or team. For GP-referred samples: referring GP name and provider number. Clinical indication may also appear here.
Results panel
Each row is one marker: name, measured value, unit (mmol/L, g/L, etc.), reference range for your age and sex, and the flag column on the right (H, L, asterisk or blank).
Pathologist comments
A clinical narrative from the reporting pathologist below each panel. PathWest hospital pathologists are medically qualified and may provide detailed clinical interpretation on complex results.
Footer
Pathologist name and FRCPA qualification, PathWest NATA accreditation statement, page number and repeated patient identifiers on every page.
Common Abbreviations on PathWest Reports
PathWest uses standard Australian pathology abbreviations. These are the most common codes you will see on a routine GP-ordered blood panel in Western Australia.
FBC / FBE
Full Blood Count / Full Blood ExaminationRed cells, white cells, platelets, haemoglobin and red cell indices (MCV, MCH, MCHC, RDW)
UEC / EUC
Urea, Electrolytes and CreatinineKidney function and electrolyte balance — sodium, potassium, chloride, bicarbonate, urea, creatinine, eGFR
LFT
Liver Function TestsLiver enzymes (ALT, AST, ALP, GGT), bilirubin, albumin and total protein
eGFR
Estimated Glomerular Filtration RateKidney filtration capacity, derived from creatinine, age and sex. Critical for monitoring chronic kidney disease
HbA1c
Glycated HaemoglobinAverage blood sugar over the past 2-3 months; primary marker for diabetes diagnosis and management
TFT
Thyroid Function TestsTSH primarily; free T4 and free T3 added when TSH falls outside the normal range
CRP
C-Reactive ProteinAcute inflammation marker in mg/L; elevated in infection, autoimmune disease and tissue injury
WAVE

Understanding PathWest Result Flags
PathWest uses RCPA-aligned reference intervals consistent with the national pathology standard. Flags are statistical signals, not diagnoses — about 5% of healthy adults have at least one flagged result on a large panel purely by chance.
H
Result is above the upper limit of the reference range printed on that row. PathWest uses RCPA-aligned reference intervals for all routine panels.
L
Result is below the lower limit of the reference range. Common on ferritin, haemoglobin, sodium, vitamin D and folate.
* (asterisk) or bold
Critical or action-level result. PathWest phones the treating team or requesting GP directly for all critical values. Hospital ward results with critical flags are reported immediately.
AB or ABNORMAL
Used on immunology, microbiology and specialist panels where a directional H/L flag is not applicable.
CR
Critical result — explicitly used on some PathWest panels to indicate a value requiring immediate clinical action beyond routine notification.
Pathologist narrative
A written comment from the reporting pathologist below the panel. PathWest hospital pathologists may include interpretive remarks about complex or unexpected results, particularly for oncology, transplant and intensive care patients.
How to Read Your PathWest Report — Step by Step
Identify whether this is a hospital or community report
PathWest serves both hospital inpatients and community GP referrals. Hospital reports include ward details and MRN/UR numbers; community reports show the GP name and episode number. The clinical context differs significantly between the two.
Confirm your demographics
Check name, date of birth and identifier numbers at the top of the report. For hospital reports, also confirm the ward and MRN match your admission. Errors in identifiers are the most common reason results appear on the wrong patient file.
Note the collection date and reporting date
PathWest shows both the collection date and the date the pathologist finalised the report. Hospital inpatient samples are often processed within hours. Community GP referrals are typically 24-48 hours.
Identify each panel by its heading
PathWest groups markers under bold panel headings (FBC, UEC, LFT, Lipids, etc.). Scan the headings first to understand the scope of what was ordered before reading individual result rows.
Read each result row against the reference range
Each row shows marker name, your value, the unit and the reference range for your age and sex. The H or L flag on the right is your first attention signal. Always use the range printed on your specific PathWest report, not a generic internet value.
Understand RCPA reference ranges
PathWest uses RCPA-aligned reference intervals. Ranges are age-specific and sex-specific where relevant — haemoglobin, ferritin, eGFR, creatinine and hormone levels all have different normal values depending on your demographics.
Read pathologist comments carefully
PathWest hospital pathologists are FRCPA-qualified and include detailed clinical commentary on complex results. Community GP reports may carry brief interpretive notes. Never skip the comment section — it often contains the most clinically relevant information.

Red Flags — Results That Need Urgent Attention
Most PathWest results can wait for your next scheduled GP appointment. The following findings warrant a same-day phone call to your doctor or treating team:
Asterisk, bold or CR flag on any result
PathWest has already contacted your treating team or GP. If you received the report yourself and have not heard from a clinician, phone your GP or ward that day.
Potassium below 3.0 or above 6.0 mmol/L
Dangerous electrolyte imbalance with cardiac risk. Requires same-day medical review.
Haemoglobin below 80 g/L
Severe anaemia. Urgent investigation needed to find the cause — active bleeding, nutritional deficiency or bone marrow problem.
eGFR below 30 mL/min
Severely impaired kidney function. Ensure prompt GP or nephrology follow-up within days.
Sodium below 125 or above 155 mmol/L
Extreme sodium disturbance. Can cause neurological emergencies. Requires same-day assessment.
Pathologist comment with urgent or action language
PathWest pathologists write explicit clinical recommendations when warranted. Always act on these promptly. Phone your GP or ward if you have not already been contacted.
PathWest Hospital Sites and Coverage
PathWest services all major WA public hospitals and extends to regional and remote Western Australia. Below are the key sites and geographic areas covered.
QEII Medical Centre laboratory (central reference lab)
PathWest's flagship reference laboratory at the QEII Medical Centre campus. Complex, specialised and tertiary-level testing is centralised here, including oncology, transplant, immunology and molecular diagnostics.
Royal Perth Hospital
PathWest provides full on-site pathology for WA's major trauma and tertiary hospital in the Perth CBD. Includes 24/7 urgent pathology for the emergency department and intensive care unit.
Fiona Stanley Hospital
PathWest services this large southern-suburbs tertiary hospital, opened in 2014. Includes pathology for the adjacent St John of God Murdoch private hospital under a shared services arrangement.
