One-line Definition
A connected home-testing product system for ovarian health.
Brief
OHST explores how AMH, LH and FSH testing could be translated into a more private and approachable home-health experience. The system combines a reader, test strips, a blood-sampling module, packaging and a companion app. Its goal is to support regular self-awareness and earlier conversations with healthcare professionals rather than replace clinical diagnosis.
Problem
Ovarian-health assessment often requires hospital visits, repeated waiting and the disclosure of intimate information. Existing home products usually focus on a single indicator, depend on visual judgement or lack long-term data management. Users therefore need a coherent system that makes testing, interpretation and follow-up easier to understand.
Research & Insights
The research compared urine-strip products, multi-hormone digital tests and laboratory AMH services, examining accuracy, waiting time, cost and data continuity. It also reviewed the clinical roles of AMH, LH and FSH to define a multi-indicator information framework. The main opportunity was not only to measure a value, but to reduce subjective reading and build a personal trend record.
Design Opportunity
A calm domestic object could lower the medical anxiety associated with self-testing while preserving the credibility of the process. By combining digital reading, Bluetooth transfer and historical records, the product could turn isolated tests into an understandable health-management journey. A gentle visual language would also make the device more acceptable in a bedroom or bathroom environment.
Concept Development
The system uses a reader to identify test-strip colour values, process the result and display it on an OLED screen before synchronising data to the app. The app presents hormone curves, alerts and historical records, and connects the user with consultation, prescription and appointment services. Product, interface and packaging were developed as one continuous experience.
Form Development
The form is based on a rounded, protective oval silhouette that feels private and non-clinical. Sketch iterations adjusted screen angle, support position, sampling module and grip to create a stable desktop presence. A circular light band and softly inclined display provide clear status feedback without making the object resemble hospital equipment.
Structure & Prototyping
The product integrates a test-strip slot, optical reading area, control board, battery, OLED screen, light band and multifunction dial. A magnetic blood-sampling module can be removed for use and returned to the reader for analysis. The architecture separates consumables, electronics and user-contact parts to clarify cleaning, replacement and maintenance.
Testing & Iteration
Foam and printed mock-ups were used to evaluate scale, screen visibility, finger access and the angle of the supporting frame. The flow was repeatedly simplified from sampling to strip insertion, reading and app upload. Iteration focused on reducing ambiguous steps and making the result visible within a short, linear sequence.
Final Design
The final proposal includes the OHST reader, magnetic sampling tool, disposable strips, mobile interface and packaging kit. A soft white body, warm light ring and restrained pink accents create a calm identity for intimate healthcare. The unified system balances technical information with an approachable domestic presence.
Use Scenario
The user inserts a new strip, uses the sampling module and returns it to the magnetic dock. The reader analyses the strip, shows the result and transfers the data to the app, where trends and alerts can be reviewed. When needed, the user can share records with a clinician or enter a consultation pathway.
Outcome
OHST demonstrates how product design can connect a physical test, digital interpretation and follow-up services into one coherent journey. The project strengthened system thinking across hardware, UI, packaging and information hierarchy. Further development would require clinical validation, regulatory review and collaboration with diagnostic specialists.
