Worried that the biggest hurdle for parent visa applications is the medical exam—especially when it comes to infectious diseases? Last week, one of our Subclass 143 clients, who has Hepatitis B “minor surface antigen positive” (commonly known as xiaosan yang), successfully passed the medical examination under our professional guidance. No re-exam required, no explanation letter—approved on the first attempt!

Yes, you read that right—good preparation + professional guidance can truly help you avoid a lot of unnecessary trouble later on!

Official Hepatitis B Health Standards (Recognized by the Department of Home Affairs):
According to official requirements, Hepatitis B virus carriers (commonly xiaosan yang) must meet the following conditions:

HBeAg negative, Anti-HBe positive

HBV DNA < 2000–20000 IU/mL

Normal ALT levels

Mild liver fibrosis (via Fibroscan)

Real Client Case (Subclass 143):

Test: Hepatitis B Virus DNA Quantitative

Result: 2.84E+03 IU/mL

Reference Range: <2.00E+01

(Although above the normal range, this still meets the immigration standard of “DNA < 20000,” classifying the applicant as a healthy carrier!)

Before the medical exam, the client proactively disclosed their Hepatitis B history. Even though the viral load was already well controlled, we still provided detailed step-by-step guidance, including:

How to communicate the condition to the medical examiner

How to explain current medication and treatment outcomes
As a result, the exam outcome met immigration health standards, and after signing Form 815, the application was approved immediately!

Hepatitis B Categories:

Major surface antigen positive (dasanyang): Highly infectious, easily causes acute hepatitis, usually leads to refusal if detected.

Minor surface antigen positive (xiaosan yang): Much weaker infectiousness. If no hepatitis symptoms are found and liver function is normal, applicants may be recognized as “healthy carriers.” The Department usually approves the visa but may require signing a Health Undertaking: within 28 days of arrival, the applicant must visit a designated institution for re-examination and determine if treatment is necessary.

What Do Parent Visa Medical Exams Include?
