A biomarker is a measurable substance or characteristic found in the blood that provides information about a biological process, condition, or disease. Blood biomarkers can be proteins, enzymes, hormones, antibodies, genetic markers, cells, or other molecules that are present in the bloodstream.

Examples of blood biomarkers include:

1. Glucose: Elevated blood glucose levels are indicative of diabetes or pre-diabetes.
2. Cholesterol: Levels of LDL (low-density lipoprotein) cholesterol and HDL (high-density lipoprotein) cholesterol are important indicators of cardiovascular health.
3. Prostate-specific antigen (PSA): PSA levels are used as a biomarker for prostate health and can be elevated in prostate cancer or other prostate conditions.
4. Hemoglobin A1c (HbA1c): This biomarker reflects average blood glucose levels over the past two to three months and is used to monitor long-term glucose control in individuals with diabetes.

These are just a few examples of the many blood biomarkers that can be analysed to assess health, diagnose diseases, and predict disease progression.

Health data is important to the well being of all people, both male and female. Whether you're trying to investigate symptoms or optimise your performance, a comprehensive panel will show you an analysis of key hormones to track.

For example, some of the key hormones that performance driven people such as bodybuilders may want to test include:

1. Testosterone: Testosterone is crucial for muscle growth and strength development. Bodybuilders often want to ensure their testosterone levels are within optimal ranges for muscle building and overall well-being.
2. Growth Hormone (GH): Growth hormone plays a vital role in muscle growth, fat metabolism, and overall body composition. Bodybuilders may monitor GH levels to assess their anabolic state and potential for muscle growth.
3. Insulin-like Growth Factor 1 (IGF-1): IGF-1 is produced in response to growth hormone and is involved in muscle growth and repair. Monitoring IGF-1 levels can provide insights into an individual's anabolic status.
4. Cortisol: Cortisol is a stress hormone that can have catabolic effects on muscle tissue if levels are chronically elevated. Bodybuilders may want to ensure cortisol levels are within normal ranges to minimise muscle breakdown.
5. Thyroid Hormones (T3 and T4): Thyroid function can play a crucial role in metabolism and energy regulation. Monitoring thyroid hormone levels can help bodybuilders optimise their metabolism and energy levels for training and recovery.
6. Estrogen and Progesterone: While primarily associated with females, both estrogen and progesterone also play roles in male physiology. Imbalances in these hormones can affect muscle growth, fat distribution, and overall health.
7. DHEA-S (Dehydroepiandrosterone sulfate): DHEA-S is a precursor to testosterone and other sex hormones. Monitoring DHEA-S levels can provide insights into overall hormonal balance and potential testosterone production.

Regular blood screening for sexual health is vital for early detection of sexually transmitted infections (STIs) such as HIV, syphilis, and hepatitis. Detection allows for prompt treatment, reducing the risk of transmission to sexual partners and preventing complications like infertility and chronic health issues.

Knowing one's sexual health status promotes peace of mind and empowers individuals to make informed decisions about their sexual practices. Early identification of STIs facilitates timely treatment and support services, including counselling and education.

Ultimately, regular blood screening for sexual health is a key component of proactive healthcare for sexually active individuals, promoting overall well-being and reducing the spread of infections.
