Quick Verdict
Forth testosterone test starts from £29, a strong second-cheapest option behind Medichecks, with a genuinely appealing upgrade path via the Tasso+ upper-arm device for anyone who finds finger-pricks unpleasant. The core finger-prick process works well for most people, but independent reviews show a real minority experience for whom it doesn’t: difficult collection, failed markers, and doctor’s comments that don’t always add much value on borderline results.
At a Glance
| Field | Value |
|---|---|
| Price (from) | £29 (single-marker testosterone); Male Hormone panel priced higher |
| What’s tested | Total testosterone (Male Hormone panel adds free testosterone, SHBG, LH, oestradiol) |
| Sample method(s) | Finger-prick (standard), Tasso+ upper-arm device (+£20 add-on), or clinic venous draw |
| Turnaround | Results typically within 2 working days of the lab receiving your sample |
| Doctor’s review included? | Yes, doctor’s comment included in the app alongside your detailed report |
| Lab accreditation | Processed via accredited partner labs |
| Company focus | General wellness and fitness-oriented blood testing, athlete-leaning panels |
What You Get, and What’s Actually Tested
At the £29 entry point, Forth measures total testosterone only. Step up to the Male Hormone panel and you’ll also get free testosterone, SHBG, LH, and oestradiol, giving considerably more diagnostic context than the base test alone, and putting it in similar territory to Randox’s Quickdraw panel, though typically at a higher price point. Forth’s broader positioning leans toward fitness and performance tracking (their panels are popular with people monitoring training load, recovery, and hormone trends over time), which is worth knowing if you’re after a one-off general check rather than ongoing performance monitoring.
Sample Collection Process
- Order online and receive your kit with instructions
- Collect your sample between 7am and 10am, when testosterone is at its natural peak
- Standard collection is a finger-prick sample taken at home, or add the Tasso+ device (+£20) for a near-painless upper-arm alternative
- Post your sample back using the included Tracked-24 envelope
- Results typically appear in the Forth app within 2 working days, alongside a doctor’s comment and a detailed report
Accuracy and Reliability Notes
The lab processing itself is generally well-regarded, and Forth explicitly reissues failed samples free of charge, which is a fair policy when things go wrong. That said, independent reviews reveal a genuine split in collection experience: many users report a smooth, quick process, but a meaningful minority describe the standard finger-prick as difficult, needing multiple pricks, struggling to collect enough blood for multiple sample pots, and in some cases having individually-priced markers fail without an automatic offer to retry them.
There’s also a recurring theme in critical reviews that the doctor’s comment on borderline or unusual results can feel thin, offering little practical interpretation beyond flagging a number as outside range. If you’ve never done a finger-prick test before, or you know you have small or hard-to-access veins, the £20 Tasso+ upgrade or a clinic venous draw is worth considering on your first attempt.
Pricing Breakdown
| Option | Price | Notes |
|---|---|---|
| Single-marker testosterone (finger-prick) | From £29 | Entry-level total testosterone only |
| Tasso+ device add-on | +£20 | Painless upper-arm collection, optional at checkout |
| Male Hormone panel | Higher tier | Testosterone, free testosterone, SHBG, LH, oestradiol |
| Clinic venous draw | Add-on cost varies | Available for those who prefer a professional blood draw |
Company Reputation
Forth positions itself toward fitness-focused and performance-minded users, with panels built around training, recovery, and hormone tracking over time rather than a purely general-health angle. This makes it a natural fit if you’re already tracking other training metrics and want testosterone data to sit alongside them, though it can feel like overkill if you just want a single, simple check. No notable conflict-of-interest pattern (such as a linked TRT clinic) surfaced in our research.
Who It’s a Good Fit For
- You train regularly and want testosterone tracked alongside other performance and recovery markers over time
- You’d rather pay a bit more (£20) for the Tasso+ device than risk a difficult finger-prick
- You want a fast, app-based results experience with a clear detailed report
Who It’s Less Suited To
- Anyone who’s had a difficult finger-prick experience before and wants the most foolproof collection method without an add-on cost
- Anyone who wants deep interpretation of a borderline result from their doctor’s comment, not just a flagged number
- Anyone who just wants the single cheapest possible baseline test. Medichecks undercuts Forth by around £10 at the entry level
How It Compares
Against Medichecks’ £19 single-marker test, Forth costs a little more at £29 but offers the Tasso+ device as a genuinely useful upgrade path that Medichecks doesn’t offer in the same way. Against Randox’s £46 Quickdraw panel, Forth’s base test is narrower, though its Male Hormone panel covers similar ground once you step up in price. See our full comparison of UK testosterone test kits for the complete picture.
Bottom Line
Forth is a solid, fitness-leaning option, particularly appealing if the Tasso+ device sounds preferable to a finger-prick. Just go in aware that the standard finger-prick collection doesn’t go smoothly for everyone, and don’t expect an in-depth clinical explanation from the doctor’s comment if your result comes back borderline.
FAQ
Is the Tasso+ device worth the extra £20?
If you’re new to home blood testing or know finger-pricks are difficult for you, it’s a reasonable upgrade. It’s designed to be a near-painless alternative collected from the upper arm rather than the fingertip.
What happens if my sample fails?
Forth reissues failed samples free of charge, though some user reviews note that individually-priced markers within a custom panel aren’t always automatically retried if only some of them fail.
Does the doctor’s comment explain what my result means?
It’s included as standard, though some independent reviews note the interpretation can feel limited on borderline or unusual results, for a fuller conversation, you may want to bring results to your GP.
Is Forth better for one-off testing or ongoing tracking?
Forth’s panels and positioning lean toward ongoing tracking, particularly for training and recovery, though a one-off single-marker test is also available.
Does Forth’s testosterone test include free testosterone and SHBG?
Not at the base £29 tier, that measures total testosterone only. The Male Hormone panel adds free testosterone, SHBG, LH, and oestradiol at a higher price.
