Type "how to increase testosterone" into Google and you'll get supplement ads, forum threads, and confident-sounding advice from people with no clinical training behind it. Meanwhile, the question itself, [UK monthly search volume TBC - confirm via a UK keyword tool before publishing; the figure on the AU version was 35,000+/month, which does not carry over], never gets the one answer that actually matters first: what are your levels doing right now?
That gap between search demand and clinical guidance is exactly where evidence-based testing should sit.
The symptom-first problem
Low energy. Reduced strength or recovery. Low libido. Flat mood. These are the reasons men start searching, and they're genuinely non-specific, the same symptom set can sit behind very different hormone pictures. Guidelines treat symptoms like these as a trigger to test, not as a diagnosis in themselves [1,2,4]. Two men with identical complaints can have opposite testosterone profiles, and "how to increase testosterone" content that skips straight to lifestyle hacks or supplements is guessing at a problem it hasn't actually measured.
A testosterone panel doesn't guess. It measures:
- Total testosterone - the primary screening marker, and the starting point for almost every panel
- Free testosterone - most useful when SHBG is abnormal or total testosterone sits near the borderline, rather than as a routine first-line addition [1-3]
- SHBG - the binding protein that determines how much testosterone is "active" versus bound
- LH and FSH (in a fuller panel) - distinguishing whether a low reading originates in the testes (primary) or upstream in the pituitary signal (secondary) [1,2]
Timing matters too. Testosterone is highest in the morning, so results are best collected fasting, before 10am [2]. And a single low reading isn't the end of the story: the Endocrine Society's clinical practice guideline notes that around 30% of men with an initial low result come back within the normal range on a repeat morning, fasting measurement, which is why a low result calls for confirmation before it means anything [2].
That's the difference between reading a symptom and reading a result.
Why this matters to practitioners too
Practitioners see the downstream version of this search behaviour constantly: patients who've already self-diagnosed, sometimes already self-treating, based on content with no clinical grounding behind it. A baseline panel, ordered without waiting on a GP referral pathway, gives both practitioner and patient a shared, objective starting point before any conversation about intervention happens. It shortens the path from "I think something's off" to an actual clinical decision.
That's the bridge i-screen sits on: direct-to-consumer accessibility, with results built to be useful in a practitioner conversation, not just a dashboard number.
Testing without the referral wait
i-screen's hormone testing runs from a focused starting point to a full picture, depending on what the question actually is:
- Male Hormone Check - testosterone, SHBG, DHEA-S, oestradiol, FSH, LH and prolactin from a finger-prick sample, for a comprehensive baseline read in one order
- Male Hormone Check (saliva) - testosterone, DHEA, androstenedione, oestradiol, oestrone and progesterone from a morning saliva sample, a non-blood alternative covering similar ground
- Advanced Dried Urine Hormone (DUTCH) Test - androgens including testosterone and DHEA, oestrogen and progesterone metabolism, and a full diurnal cortisol pattern across the day, for anyone whose question extends into adrenal function and daily hormone rhythm rather than a single snapshot
All ordered online, with results delivered to a dashboard, no GP referral required to get started.
The takeaway
The pattern is a clear signal: men want to understand their hormones, and right now, most of what they find doesn't help them do that. Testing first, then acting on what the result actually shows, is the more useful order to do things in. That's the position i-screen is built on.
