HORMONE TEST
Hormonal imbalances can silently affect your mood, weight, energy, skin, and overall vitality. Dr. Jinah Yoo's advanced hormone testing provides a comprehensive picture of your hormonal health, enabling a personalised treatment plan to restore balance and optimise your wellbeing from within.
Hormone testing is a vital step toward understanding your body and unlocking long-term health and vitality.
WHAT IS A HORMONE TEST?
A hormone test is a precise diagnostic tool that analyses your body's key hormonal levels — including oestrogen, progesterone, testosterone, cortisol, thyroid hormones, and DHEA. At Dr. Jinah Yoo Clinic, we use advanced blood and saliva panel testing to identify imbalances that may be contributing to fatigue, weight gain, mood changes, poor sleep, skin issues, and reduced libido. Understanding your unique hormonal blueprint is the foundation of truly personalised regenerative care.
BENEFITS OF HORMONE TESTING
- Identifies Root Causes of Symptoms: Hormone testing goes beyond surface-level symptoms to reveal the underlying imbalances driving fatigue, brain fog, weight fluctuations, and mood instability.
- Supports Healthy Skin & Hair: Hormonal fluctuations are a leading cause of acne, hair thinning, and premature ageing. Testing enables targeted interventions to restore skin clarity and hair vitality.
- Optimises Metabolism & Weight Management: Imbalances in thyroid and adrenal hormones can significantly impair metabolism. Testing pinpoints these issues to support effective, sustainable weight management.
- Improves Energy, Sleep & Mental Clarity: Correcting cortisol and melatonin imbalances through data-led treatment restores energy cycles, deepens sleep quality, and enhances cognitive function.
- Supports Reproductive & Sexual Health: Assessing oestrogen, progesterone, and testosterone levels helps address issues related to fertility, libido, PMS, perimenopause, and menopause management.
- Enables Personalised Treatment Plans: Results guide a bespoke approach — whether through bio-identical hormone therapy, nutrition, supplementation, or regenerative treatments — unique to your biology.
HORMONE TESTING & LONGEVITY
Hormonal balance is intrinsically linked to the ageing process and long-term vitality. At Dr. Jinah Yoo Clinic, we view hormone testing as a cornerstone of our regenerative longevity programme. Declining levels of oestrogen, testosterone, DHEA, and growth hormone are directly associated with accelerated cellular ageing, reduced bone density, cognitive decline, and diminished physical performance. By monitoring and optimising your hormonal profile over time, we can meaningfully slow the biological ageing process, enhance your quality of life, and support your body's natural regenerative capacity — helping you look, feel, and function at your very best.

The staff was welcoming, and the therapist was knowledgeable and attentive. The clinic is clean and modern, and I am very pleased with my treatment results. Highly recommend!
I had a great experience here at Dr Jinah Yoo! I had the ‘brightening’ treatment after having too much sunburn on my summer vacation and it really helped. The process was very enjoyable thanks to the skillful and gentle practitioner. I will come back in the future if I have any needs for skin improvements!
A perfect experience! I had the rf facial which is for lift up. The therapist is very professional and the environment is also very helpful for relaxing. Nice location as well.
Absolutely love the place. Had some moles removed from my face by Dr Yoo. A week later there is not the slightest indication that there was ever even anything there. Results are incredible.

FREQUENTLY ASKED QUESTIONS
HORMONE TEST FAQ'S
What does a hormone test check?
A gut microbiome test analyses the full composition of microorganisms living in your digestive system — including bacteria, fungi, parasites, and other microbes. It maps bacterial diversity, identifies beneficial and harmful species, measures inflammation and intestinal permeability markers, assesses short-chain fatty acid production, and evaluates how your microbiome is influencing your immune function, metabolism, skin health, and energy levels.
How is the hormone test carried out?
The test is stool-based and entirely non-invasive. After your initial consultation, you receive a discreet at-home collection kit. A small sample is taken at home at your convenience and returned to the accredited laboratory via a prepaid, temperature-controlled courier. No clinical procedure or clinic visit is required for the sample collection itself.
How do I know if I need a hormone test?
The test is particularly recommended if you experience persistent bloating, IBS, or irregular digestion; chronic fatigue or low energy with no clear cause; recurring skin conditions such as acne, rosacea, or eczema; frequent illness or poor immune resilience; low mood, brain fog, or poor concentration; unexplained weight gain or difficulty managing weight; or if you are looking to establish a detailed health and longevity baseline.
Is hormone testing suitable for men?
Yes, the gut microbiome test is equally suitable for men and women. Microbiome imbalance affects both sexes and has been linked to a wide range of concerns in men including fatigue, metabolic dysfunction, low testosterone, poor sports recovery, digestive issues, and skin conditions. Dr Yoo will tailor the interpretation and restoration plan to your individual health profile regardless of sex.
How long does it take to receive results?
Results are typically available within 2–3 weeks of the laboratory receiving your sample. Once your report is ready, a follow-up consultation with Dr Yoo is scheduled to review your findings in detail, discuss what they mean for your specific health concerns, and present your personalised microbiome restoration plan.
Can hormone testing help with weight loss?
Yes. Specific gut bacterial profiles have a direct influence on how efficiently the body extracts calories from food, stores fat, and regulates appetite hormones such as ghrelin and leptin. The test can identify microbial patterns that are contributing to weight management difficulty, and the personalised plan that follows — including dietary adjustments, targeted probiotics, and complementary treatments such as bespoke IV drips or NAD+ therapy — can support more effective and sustainable weight management.
