Douglass Hanly Moir Pathology — usually shortened to DHM — is the largest pathology provider in New South Wales, with more than 500 collection centres across metropolitan Sydney, regional NSW and north-west Victoria. DHM is part of Sonic Healthcare, the same group that owns Sullivan Nicolaides (QLD), QML (QLD) and Dorevitch (VIC). If your GP has referred you for blood tests in Sydney or NSW, there is a strong chance the report came back from DHM.
This guide explains exactly how to access your DHM results online, how to read each section of the report, what the abbreviations mean, an important gotcha about DHM''s billing policy, and how to track every biomarker over time using a free online tool.
How to access your DHM results online
You have three options for getting your Douglass Hanly Moir results:
- MyResults Patient Portal at dhm.com.au — register with your name, date of birth and Medicare number. You will receive an email when each result is finalised. Results are typically available within 1–3 business days of collection, and you can view, download and email a PDF copy of every report.
- My Health Record — since 15 April 2025, DHM automatically uploads all pathology results to My Health Record. Access through myhealthrecord.gov.au or the My Health Record mobile app — no separate registration with DHM required.
- Through your GP — your doctor receives results electronically as soon as they are available, usually before they appear in patient portals.
Tip: do not wait for your follow-up GP appointment to look at your results. Reading your own report a few days before lets you arrive informed and ask better questions.
An important DHM-specific note: billing
Unlike most major Australian pathology providers, DHM does not bulk bill by default. Bulk billing only applies when:
- Your referring doctor has a bulk-billing agreement with DHM, OR
- You are a concession card holder (Pensioner Concession Card, Health Care Card, DVA card), OR
- Your doctor has specifically marked the request as bulk-billable
If none of these apply, DHM will issue an account for the out-of-pocket portion after Medicare rebates. The exact gap varies by test — common LFT or FBC panels are typically $10–$30 out-of-pocket; specialty hormone, fertility and genetic panels can run $50–$200+. If cost matters, confirm with your GP before collection — many GPs route patients to a different bulk-billing lab (Laverty in NSW is fully Sonic-aligned and bulk bills most tests; 4Cyte and Medlab also have wide bulk-billing footprints).
The structure of a DHM pathology report
DHM reports follow the standard RCPA (Royal College of Pathologists of Australasia) format used by all major Australian pathology providers. Each report contains:
- Header: your name, date of birth, Medicare number, the requesting doctor, the DHM collection centre, the collection date and time, and a unique accession number.
- Tests grouped by panel: Full Blood Count (FBC), Liver Function Test (LFT), Iron Studies, Lipid Panel, Hormone Profile, Thyroid Function, EUC (Urea/Electrolytes/Creatinine), HbA1c, and any specialty panels your doctor requested.
- For each marker: the abbreviated name (e.g. ALT), your numeric value, the unit (e.g. U/L), and DHM''s reference range.
- Flags: DHM uses an H or L marker for results above or below the reference range. Some reports include comparator results from your previous DHM tests at the same lab — useful for spotting trends.
- Pathologist comments: DHM pathologists add interpretive notes for unusual, critical or markedly abnormal results.

| HbA1c | Glycated Haemoglobin | 3-month average glucose |
| SHBG | Sex Hormone Binding Globulin | Hormone-binding protein |
| FAI | Free Androgen Index | Calculated free testosterone marker |
| LH / FSH | Luteinising / Follicle Stimulating Hormone | Pituitary reproductive hormones |

Reference ranges on DHM reports
DHM uses RCPA-aligned reference ranges with sex- and age-adjustments where appropriate. A few worth knowing:
- ALT: men <40 U/L, women <35 U/L (slight variation by individual lab)
- Ferritin: men 30-300 µg/L, women 15-200 µg/L (RACGP defines iron deficiency as <30 µg/L)
- TSH: 0.4-4.0 mIU/L (some specialists use a tighter 1.0-2.5 mIU/L "optimal" range, especially during pregnancy planning)
- HbA1c: <5.7% normal · 5.7-6.4% prediabetes · >6.4% diabetes
- Total testosterone: men 8-29 nmol/L (declines ~1-2%/year after 30) · women 0.5-2.5 nmol/L
- 25-OH Vitamin D: 50-150 nmol/L sufficient · 30-49 mild deficiency · <30 moderate-severe deficiency
Note: "normal" is not the same as "optimal". Reference ranges describe statistical population norms, not the level associated with the lowest disease risk. A TSH of 3.8 is "normal" but many specialists target 1.0-2.5. Ferritin of 25 is "normal" at some labs but often symptomatic.
The H and L flags on DHM reports
DHM flags out-of-range results with H (high) or L (low). Some markedly abnormal values get HH or LL. A few principles:
- An isolated mild flag (just outside the reference) is often non-significant. Recent infection raises ferritin and CRP. Recent intense exercise raises CK and AST. Dehydration raises urea and haematocrit. Repeat in 4-8 weeks if your GP agrees.
- Multiple flagged markers in the same panel usually tell a coherent story. Low ferritin + low haemoglobin + low MCV + low MCH = iron deficiency anaemia. High ALT + high AST + high GGT = liver injury (cause depends on the ratio).
- HH/LL flags (markedly out of range or critical values) — the DHM pathologist will usually call your GP directly. Take these seriously and schedule a prompt review.
How to track your DHM results over time
DHM will show your previous result alongside the current one on the report — but only for the most recent test at the same lab. They do not aggregate across labs, do not chart visually, and do not let you compare against optimal ranges or condition-specific patterns. If you have ever moved interstate or switched between DHM, Laverty, ACL or any of the Sonic/Healius labs, your trend history is broken.
BloodTrack solves this. Upload your DHM PDF and BloodTrack:
- Extracts every biomarker from the DHM format automatically
- Maps each result to RCPA-aligned reference ranges
- Charts every marker over time across any Australian pathology provider — useful if you have moved between providers or interstate
- Flags out-of-range and near-boundary results
- Surfaces condition-specific patterns (PCOS, TRT, fatty liver, iron deficiency, thyroid)
It works entirely in your browser — no download, no app store. Try uploading your DHM PDF, no account needed for your first analysis.
Home visits and special services
DHM offers home collection visits for patients who are infirm or too unwell to attend a collection centre. This requires a referral from your doctor and is subject to medical-eligibility assessment by DHM. Select DHM collection centres also offer ECG, Holter monitoring, ambulatory blood pressure monitoring, glucose tolerance testing and specialised paediatric collection. Ask your GP whether your closest DHM collection centre offers these.
What if there is something wrong with my DHM report?
Pathology reports occasionally have errors — wrong sample, mis-labelled test, transposed results. If something on your report looks clearly inconsistent (e.g. men''s reference ranges applied to a female patient, or a test you did not have appearing on the report), contact DHM on 1800 555 100 or (02) 9855 5100 (results line) or your referring GP. For billing queries, contact DHM Accounts on (02) 9855 5500. Most issues are resolved quickly with a re-issue or correction.
