Biomarkers are measurable substances in the blood and body that can give insight into your health when analysed by experts. Through tests like blood panel (biomarker) analysis and ECG testing, your physician can look for early signs of issues related to heart health, hormones, inflammation, cholesterol, blood sugar, and more.
Since many health issues can develop before symptoms appear, Australians are becoming more interested in preventative health and early screening. In this article, we’ll explain what biomarkers are, the insights they can provide, and the markers physicians look at as part of your comprehensive health screening.

Biomarker testing compared to standard blood tests
Blood tests are often ordered to identify an existing health issue, or monitor an existing condition. In these tests, they often only look at a smaller number of markers related to your symptoms and then match them within broad “normal” ranges.
This means that early signs of issues such as inflammation, insulin resistance, hormonal imbalances, or cardiovascular risk can sometimes go unnoticed.
In contrast, advanced biomarker testing takes a more detailed look at how the body is functioning. This test analyses a wider range of biomarkers, which allows your physician to identify subtle changes and hidden risk factors earlier. This test is all part of taking a personalised and proactive approach to your long-term health.

Common misconceptions about biomarker testing
Understanding what biomarkers can, and can’t, show you is an important part of preventative health screening. Here are some common misconceptions and the truth behind them.
“If my results are in range, I’m healthy”
The standard ranges are broad, and results can still point to early risk even if they are technically “normal.” Especially for women, looking beyond averages is important because, historically, testing ranges have also been more heavily based on male data. This can make subtle hormonal, metabolic, or iron-related issues in women easier to overlook in a standard blood test.
“Cholesterol is the only marker that matters for heart health”
Cholesterol is one part of the picture. Advanced biomarkers like ApoB, Lipoprotein(a), inflammation markers, and ECG testing can provide a more detailed understanding of your cardiovascular risk. This includes risks that may not appear in a standard cholesterol panel.
“I feel fine, so there can’t be an issue”
As we know, many health conditions develop gradually and quietly over time. Small changes in blood sugar, inflammation, cardiovascular health, or hormones can begin years before symptoms become noticeable, which is why preventative screening is important.
“Advanced biomarker testing is unnecessary”
Standard blood tests are often designed to check for existing conditions, while advanced biomarker testing provides a much deeper understanding of how your body is functioning overall. This is particularly important because it looks at a wider range of markers and how they work together, allowing doctors to identify subtle changes and hidden risk factors that may not appear in a standard blood test.
The key biomarkers your physician will look at
Different biomarkers give your physician insight into different areas of your body. Looking at all these markers together helps build a clearer picture of your overall health and any potential risk factors. Here are the key ones we will scan for.
General health and metabolic markers
These biomarkers provide a broad overview of how the body is functioning and can help identify early metabolic or blood-related changes.
These markers help assess blood health, blood sugar regulation, metabolism, and other early signs of dysfunction.
Cardiovascular health
Cardiovascular biomarkers and ECG testing provide insight into heart health and circulation.
- Total cholesterol
- LDL cholesterol
- HDL cholesterol
- Triglycerides
- Apolipoprotein B (ApoB)
- Lipoprotein(a)
- ECG testing
Together, these markers can help identify hidden inflammation or changes in heart rhythm that may not appear in a standard cholesterol test alone.
Hormonal balance
Hormonal biomarkers play an important role in energy, metabolism, mood, and overall well-being. These often change over our lives, so it’s important to check in and make sure everything is working as it should be.
- Testosterone
- Sex hormone binding globulin (SHBG)
- Estradiol
- Thyroid-stimulating hormone (TSH), including T3 and T4
If your physician notices imbalances in these markers, it can sometimes be linked to fatigue, weight changes, low mood, poor sleep, or changes in metabolism. For women, this may also include changes related to menstrual cycles, perimenopause, or menopause.
Nutritional status
Nutritional biomarkers assess whether the body has the nutrients it needs to function properly.
- Vitamin D
- Vitamin B12
- Folate
- Iron
- Ferritin
Low levels in these markers may contribute to symptoms such as low energy, poor concentration, reduced immunity, or ongoing fatigue. Getting insights here can also support body composition or training.
Kidney health
Kidney biomarkers assess how well the kidneys are functioning and filtering waste products from the blood. This is important because the kidneys help regulate hydration and blood pressure.
These markers can help identify early changes in kidney function and overall metabolic health.
Inflammation and immune function
Inflammation biomarkers can provide insight into immune activity and hidden inflammation in the body, even before symptoms develop.
- White blood cell count
- Neutrophils
Changes in these markers can sometimes suggest inflammation, immune system stress, infection, or increased long-term health risk.
Liver function
Liver biomarkers assess how well the liver is functioning, including how it processes nutrients and supports metabolism.
Changes in these markers can sometimes point to liver stress, inflammation, alcohol-related strain, or even early metabolic changes before symptoms appear.
Prostate health
For men, checking prostate-specific antigen (PSA) can provide additional insight into prostate health and age-related changes.
Electrolytes and fluid balance
These biomarkers assess hydration, nerve signals, muscle function, and heart rhythm.
- Sodium
- Potassium
- Chloride
- Bicarbonate
Imbalances in these markers can sometimes be linked to simple dehydration. Other times, they might indicate kidney stress, hormonal changes, or other issues.
How does this all connect?
When we do a biomarker test at HealthScreen, we never look at the individual marker in isolation. Instead, we review them together to build a more complete understanding of your health. This then supports us in building a plan for your personalised, preventative health approach.
Why does early detection matter?
Many health issues begin developing long before symptoms appear. Biomarkers can help identify subtle changes in the body earlier, giving patients more opportunity to take a proactive approach to their health.
For example, biomarkers may show:
- Rising insulin levels before diabetes develops
- Increased inflammation before symptoms appear
- Early liver or metabolic stress
This is one of the biggest differences between standard blood tests and advanced biomarker testing. Advanced biomarkers can help identify hidden risk factors and early changes that may otherwise go unnoticed.
Plus, by tracking biomarkers over time, physicians can monitor whether your health is improving, staying stable, or moving in the wrong direction. This helps guide more personalised decisions around lifestyle changes.

FAQs
What are biomarker tests?
Biomarker tests measure different markers in your blood and body to give doctors a better understanding of your health. They can help identify early signs of issues related to heart health, hormones, blood sugar, inflammation, nutrition, and more.
Can biomarkers indicate cancer?
Some biomarkers can show changes in the body that can lead to further investigation, but they can’t diagnose cancer on their own. Instead, they are part of a broader preventative health screening program.
Who should get biomarker testing?
Biomarker testing can be helpful for anyone wanting a more detailed understanding of their health. If you’re interested in preventative health, early screening, or tracking your health over time, it’s a great, non-invasive screening tool.
How long do biomarker test results take?
Most biomarker test results are usually available within a few business days. Your physician will then review the results with you during your follow-up consultation.
