Hormones
Total Testosterone
The total testosterone in your blood, bound and unbound. The headline number for tracking your levels before and during therapy.
Free Testosterone
The unbound, biologically active fraction, often the more useful read of what your body can actually use.
SHBG
The protein that binds testosterone and sets how much is free. Helps interpret total and free testosterone together.
Free Androgen Index
A calculated ratio of testosterone to SHBG that puts your free testosterone in context.
Oestradiol
The main oestrogen, which testosterone converts into. Tracked on TRT for its role in mood, water retention and libido.
LH & FSH
Pituitary signals to the testes, showing how your own production and fertility markers are responding.
Prolactin
A pituitary hormone measured because raised levels can affect testosterone, libido and energy.
Progesterone
Measured as part of the wider hormone picture.
IGF-1 & Growth Hormone
Markers of the growth hormone axis, relevant to recovery, body composition and energy.
Cortisol & DHEAS
Your main stress hormone and an adrenal androgen, reflecting how stress and adrenal output sit alongside your hormones.
Safety & general health
PSA
Prostate specific antigen, a prostate safety marker commonly tracked over time on TRT.
Full Blood Count (haematocrit)
Includes haematocrit, the proportion of red cells in your blood. A key safety marker on TRT, which can raise red cell production.
Liver & Kidney Function
Liver enzymes and kidney markers (EUC and eGFR), a general safety and health check alongside your hormones.
Calcium, Magnesium & Phosphate
Core electrolytes and minerals that support muscle, nerve and bone function.
HbA1c
Your average blood glucose over roughly three months, a marker of longer-term metabolic health.
hs-CRP
High-sensitivity CRP, a marker of low-grade inflammation linked to cardiovascular risk.
Advanced cardiovascular
Full Lipid Profile
LDL, HDL and triglycerides. Tracked because TRT can shift your lipid profile over time.
ApoB
A count of the cholesterol particles most associated with cardiovascular risk, a more precise read than standard cholesterol.
Lipoprotein(a)
A largely inherited, independent cardiovascular risk marker, usually worth measuring once.
Homocysteine
An amino acid linked to cardiovascular and B-vitamin status, adding depth to the cardiovascular picture.
Metabolic & thyroid
Fasting Insulin & HOMA-IR
Your fasting insulin and a calculation of insulin sensitivity, early markers of how your body handles blood sugar.
TSH, Free T3 & Free T4
A full thyroid panel. Thyroid affects energy and can overlap with low-testosterone symptoms.
Nutrients & minerals
Iron Studies with Ferritin
Iron, ferritin and related markers reflecting your iron stores, relevant to energy and, with a full blood count, red cell health.
Vitamin D
Supports bone, muscle and immune health.
Zinc
A mineral involved in testosterone metabolism and immune function.
