When discussions about gestational diabetes testing focus on attendance rates, capacity, or throughput, it’s easy to lose sight of the most important perspective: the expectant mother’s experience. Preference, comfort, and practicality are not “soft” outcomes. They directly influence engagement, completion, and trust in care pathways.
On GTT@home’s implementation in various NHS trusts, we have collected structured feedback from women who completed their oral glucose tolerance test using GTT@home. The results are striking; not just in how positive they are, but in how consistent they have remained across 6500 of completed tests.
User Experience Survey Results
20% of women who completed their OGTT with GTT@home rated their experience as follows:
• 5 out of 5: 62%
• 4 out of 5: 30%
• 3 out of 5: 5%
• 2 out of 5: 2%
• 1 out of 5: 1%
The small proportion of neutral and negative feedback was directed at the OGTT itself, not GTT@home. Comments most often referred to fasting, nausea, and the two-hour test duration - inherent features of the procedure regardless of setting. Notably, those same factors were frequently cited in positive feedback as being significantly easier to manage at home than in a clinical environment, highlighting that the critique lies in the test, not the delivery model.
It is important to acknowledge that this feedback is, by definition, drawn from women who completed the test and chose to leave a review, which introduces a degree of positive skew. However, that skew is limited by the fact that 97% of women who receive a GTT@home test go on to complete it and have therefore had the chance to rate their experience.
Taken together, 92% of respondents rated their experience 4 or 5 out of 5.
Qualitative Feedback
In healthcare, especially maternity care, that level of positive feedback at this scale is unusual. It invites a deeper question: what are women responding to?
The feedback consistently points to one thing - choice.
For the first time, women are able to decide when testing happens in a way that fits their lives. Instead of navigating early-morning hospital appointments, travel while fasting, childcare arrangements, or time off work, they can integrate testing into their own routines. That autonomy matters.
Some women start the test early, before the rest of the household wakes up. Others complete it before work to avoid using annual leave. Some time it around caring responsibilities, with partners supporting childcare during the two-hour test window. The common thread is not convenience alone, but control.
Importantly, this preference does not reflect a desire to disengage from care. Quite the opposite. High satisfaction scores are paired with high completion rates and detailed, thoughtful feedback. Women are not opting out of testing; they are opting into a pathway that respects their time, energy, and circumstances. Non-attendance and delayed testing are often framed as patient failure. Our feedback data suggests a different interpretation: when pathways are designed around real lives, women engage willingly and positively.
Patient preference is not about offering “nice-to-have” options. It is about designing diagnostic pathways that people can realistically complete - and want to complete. The data is clear: when women are given choice, trust, and flexibility, the response is overwhelmingly positive.
