Testosterone
Testosterone
The headline androgen — but only useful when read alongside SHBG, LH and FSH.

Six numbers, one diagnostic picture.
The Hormone Panel 01 measures six markers — Total + Free Testosterone, FSH, LH, SHBG, Estradiol, Prolactin — and each answers a different clinical question. Total tells you what is circulating; SHBG decides bioavailability; FSH and LH localise testicular versus pituitary causes; Prolactin screens for upstream pituitary pathology; Estradiol catches the feedback-loop effects most GP panels miss.
Click through for the clinical detail behind every number on your panel — what it measures, the adult male reference range, what low and high values suggest, and how it reads in combination with the other five markers.
Follicle-stimulating hormone
FSH (Follicle-stimulating hormone)
Pituitary-side signal that drives spermatogenesis. The single most useful marker for testicular function.
Read the marker brief →Luteinising hormone
LH (Luteinising hormone)
The pituitary signal that tells the testes to produce testosterone.
Read the marker brief →Sex hormone-binding globulin
SHBG (Sex hormone-binding globulin)
The protein that decides how much of your testosterone is actually free to act.
Read the marker brief →Estradiol
Estradiol (E2)
The downstream oestrogen — quietly essential for libido, bone, brain and feedback control.
Read the marker brief →Prolactin
Prolactin
A pituitary hormone that, when elevated, can suppress the entire male reproductive axis.
