Diabetes Test

A single blood test for HbA1c (glycosylated haemoglobin), which reflects your average blood sugar level over roughly the past three months. Suited to people with diabetes symptoms or an existing diagnosis who want to check how well their blood sugar is being controlled.

About this test

HbA1c, also called glycosylated haemoglobin, forms when glucose in your blood attaches to haemoglobin in red blood cells. Because red blood cells last around four months, the level of HbA1c reflects your average blood sugar over that period rather than a single moment, which makes it useful for checking how well diabetes is being controlled or for investigating symptoms such as increased thirst, frequent urination or unexplained weight loss.

Scored against the wider set of diabetes tests we track, this listing scores very poorly on price, coming in well above the median for similarly sized diabetes tests. It sits in the lower half for clinical depth as a single marker, and mid-table for collection convenience, since it requires a venous blood draw at a clinic with results back within about a day. It loses marks on results and follow-up because a doctor does not routinely review your result.

On trust signals, Better2Know scores a 4.2 on Trustpilot from 775 reviews, is CQC registered, and has traded since 2008.

Who is it for?

This suits people who have been diagnosed with diabetes and want to check how well their blood sugar has been controlled over the past few months, or anyone investigating persistent symptoms who wants an HbA1c reading specifically. Given how far this listing's price sits above the category median for a single marker, it is worth checking whether a cheaper single-marker HbA1c test, or a combined glucose and HbA1c test, meets your needs before booking.

There are no comparable tests recorded for this listing, so we cannot name a specific cheaper alternative.

How it works

A clinician takes a small venous blood sample at a Better2Know clinic and sends it to the laboratory for analysis. Results are typically available within about a day of the sample arriving and are uploaded to your secure online patient area, with email or SMS notification when ready. The provider does not state that a doctor reviews your result as standard; if it falls outside the normal range, Better2Know can arrange a doctor consultation to discuss treatment options.

Pros & cons

Pros

  • Clear description of what HbA1c measures and how it is used
  • Fast turnaround of around 1 day once the sample reaches the lab
  • Doctor consultation available if your result needs discussing

Cons

  • Priced well above the median for similarly sized diabetes tests we track
  • Only measures one marker, so gives no current glucose reading
  • Results are not reviewed by a doctor as standard

Our editorial score

Compare Health Test Score Single HbA1c marker priced well above the median
Editorial confidence: 9.0/10

This test measures only HbA1c, the marker that shows your average blood sugar over about three months, for £135. That is well above the median price for the diabetes tests we track, and it requires a venous blood draw at a clinic rather than an at-home kit.
