Industry & Use Cases

From longevity to fertility: use cases for laboratory diagnostics as a service

Home-sampling diagnostics fits anywhere lab values can make an offering more precise, more accessible or more controllable — across sectors. This article shows typical use cases without making medical efficacy claims, focusing on the programme value in each case. The diagnostic result always comes from an accredited laboratory, never from the end user.

GLP-1 and weight-management programmes

GLP-1-based therapies (semaglutide, tirzepatide and others) require an eligibility check before they begin (safety parameters, exclusion of certain risks) and follow-up diagnostics during treatment (metabolism, liver and kidney values, thyroid).

A typical, sensible panel for companion diagnostics:

  • Lipid profile (total cholesterol, LDL, HDL, triglycerides) — metabolic baseline.
  • HbA1c — long-term blood glucose as a follow-up parameter.
  • Liver values (ALT, AST, GGT) — safety monitoring.
  • Thyroid function (TSH) — relevant in some GLP-1 therapies.
  • Kidney values (creatinine, eGFR) — companion safety.

What home sampling adds here: programme participants complete pre- and in-therapy diagnostics without a clinic visit, with the result delivered into the programme app. That reduces drop-out rates and creates a safer accompanying workflow. We deliver diagnostics — not therapy and no efficacy claims.

Testosterone deficiency / men’s health

Hormone status (total testosterone, free testosterone, SHBG, optionally LH/FSH) as the basis for advice or a therapy indication. Providers in the men’s health space use this as an entry point — with the Testosterone Profile or Men’s Hormone Profile as the standard panel.

Screening & prevention

  • Cardiovascular — lipid profile, hsCRP, Lp(a) in preparation.
  • Diabetes early detection — HbA1c, fasting glucose.
  • Colorectal cancer — iFOBT (immunochemical faecal occult blood test).
  • Prostate cancer — PSA screening by home sampling (a first in this form in Germany, nationwide).
  • HPV / STI — urine- or swab-based screening.

What they share: low threshold, high uptake. Diagnostics reach insured members where they already are — in their living room.

Longevity & prevention

Programmes in the longevity space (anti-ageing, healthy ageing, performance diagnostics) live on recurring biomarker trajectories. Rather than a single measurement, a profile is built over time — trends matter more than individual values. Home sampling makes this repeated diagnostics practical.

Fertility

Hormonal diagnostics for couples trying to conceive (e.g. AMH, FSH, LH, oestradiol, testosterone), as preliminary or accompanying diagnostics — via the Fertility Profile on both the female and male side. Reduces appointment load in fertility clinics.

Menopause / women’s health

The Menopause Profile provides a hormonal picture for follow-up — for example to monitor hormone therapy or to establish a baseline in counselling sessions.

Thyroid

The classic Thyroid Profile with TSH, fT3, fT4 — often extended with autoantibodies where an autoimmune cause is suspected.

Micronutrients / vital substances

Vitamin D, B12, iron status, ferritin, magnesium and others — via Vitamin D Check Plus, Nutrient Analysis Plus or Energy Status, depending on programme depth.

Sports / performance profiles

Markers for endurance, recovery, overtraining — via Fitness Check Pro and topic-specific panels.

Allergy / intolerance

Specific IgE diagnostics through to the Allergy Screening (up to 295 allergens) and Intolerance Checks (e.g. 286 foods).

Gut health

Functional programmes around digestion draw on the Gut Flora Check (microbiome profile) or the iFOBT method — complemented by liver and metabolic profiles.

Common ground

In each of these fields the same quality foundation applies:

  • Analysis in an accredited laboratory — not a self-test with self-interpretation.
  • Validated parameters — stability on the shipping route is documented.
  • Digital routing — the result arrives in your system in a structured form, automatically.

Which parameters can actually be analysed from which sample type is covered in the companion article. Why home sampling and self-test are two different things from a regulatory perspective is explained here.

FAQ

Frequently asked questions

Which use cases is home sampling suited to?

Anywhere lab values make a digital health offering more precise: therapy companion diagnostics (e.g. GLP-1), hormonal diagnostics, prevention programmes, longevity, micronutrients, fertility, menopause, thyroid, sports and performance profiles, allergy and intolerance testing, gut health, STI screening. The prerequisite: the parameter in question is validated for shipment via the home route.

Is diagnostics suitable to accompany GLP-1 programmes?

Yes — as companion diagnostics before therapy begins (eligibility check, safety parameters) and during therapy (follow-up monitoring). Typical building blocks are lipid profile, HbA1c, liver values, thyroid function and kidney values. Which parameters make sense in detail is programme-specific and tailored during setup.

Can I put together my own panels for my use case?

Yes. Probatix designs a tailored panel with you based on your programme. Standard panels (e.g. lipid profile, hormone status, micronutrients) can be extended or trimmed selectively — within what the laboratory has validated.
