Define the clinical question
We document the method, record results and distinguish measured findings from editorial judgment.
Inside the MedsCompass test process
How we plan, measure, challenge and interpret a product before reaching an editorial verdict.
A repeatable six-stage review
Products face the same sequence so comparisons remain meaningful.

Bench test with calibrated tools
We document the method, record results and distinguish measured findings from editorial judgment.
Use in everyday conditions
We document the method, record results and distinguish measured findings from editorial judgment.

Score, review and update
We document the method, record results and distinguish measured findings from editorial judgment.
Measurement before recommendation
Accuracy, repeatability, usability, safety evidence, build and ownership cost are scored separately before the final result is calculated.
How a device moves from first inspection to final score
Our protocol separates controlled measurement, human-factors assessment and documentary evidence so that one attractive feature cannot conceal a weak result elsewhere.
We define the question before seeing the result
Each review begins with the device’s intended use, target user, measurement method and clinically important failure modes. We set the comparison criteria, sample sequence and pass thresholds in advance, then apply the same core procedure to every product in a category.
Category-specific checks are added where appropriate. A blood pressure monitor is assessed for cuff fit, positioning guidance and repeatability; a pulse oximeter is also challenged with motion, finger placement and low-perfusion limitations.
Repeated readings matter more than a single best result
Devices are stabilised, reset and tested in a repeatable sequence. Where suitable equipment is available, measurements are compared with a calibrated reference or simulator across representative points in the operating range. We record absolute difference, clustering, failed readings and unexpected variation.
A product is not rewarded for one favourable reading. We look for a pattern that remains consistent after refitting, repositioning and repeating the procedure under the same conditions.
Correct technique must be achievable at home
Instructions, controls, display contrast, error messages, accessibility and recovery from common mistakes are assessed as part of performance—not as cosmetic extras. A technically capable device loses marks when ordinary users are likely to obtain a poor result because its guidance is unclear.
Extended-use checks cover comfort, setup time, storage, cleaning, battery or charging behaviour, memory retrieval and the practical work needed to share a useful series of readings.
Claims are checked against their strongest available source
We examine current instructions, regulatory databases, validation material, safety communications and relevant published evidence. Manufacturer language is treated as a claim to verify, not as an independent conclusion.
Regulatory clearance, validation and clinical usefulness are not interchangeable. Reviews state what was confirmed, what remains uncertain and whether evidence applies to the exact model and population being discussed.
SCORING & REVIEW
A weighted result with safeguards against false precision
Category weights reflect the device’s purpose. Measurement performance and repeatability receive the greatest influence for a monitoring device; usability, evidence quality, build and value are scored independently. Serious safety concerns or unreliable core performance cannot be cancelled out by a low price or polished app.

Editorial and clinical safeguards
Review notes retain the model identity, test period, relevant settings and source material. Material technical or medical claims are checked before publication, and commercial partners do not see or approve our verdict in advance.
Reviews are revisited when an important recall, safety communication, specification change or stronger body of evidence becomes available. Corrections that could change a buying decision are made clearly and dated rather than silently rewritten.
