A full blood count with a 5-part differential plus ESR, covering red cells, platelets and five white cell types, from a venous blood sample. Suits people who want a general check on blood cell health without a wider chemistry panel.
9 biomarkers as listed by Better2Know.
This test gives a full blood count (FBC) with a 5-part differential, covering red blood cells, platelets and five types of white blood cell, plus the erythrocyte sedimentation rate (ESR), which can indicate inflammation. It is aimed at people who want a general read on blood cell health, drawn from a single venous blood sample.
Within its 'Essential health check' comparison group, this is the most expensive listed test at £145, against a group median of £113. It also tests fewer markers than most of its peers: Monitor My Health's Essential Health Screen covers the same 9 markers for £49, and several peers, including Blue Horizon Medicals' 20-marker Fingerprick Wellman and Fingerprick Wellwoman tests at £82.25, cover considerably more for less money.
Clinical depth scores modestly, since its 9 markers sit below the group's median of 18, and value for money is weak given the above-median cost. Clarity scores well, as Better2Know publishes a full description, the marker list, turnaround and collection options. Results and follow-up also holds the score back, since results are not reviewed by a doctor as standard.
This suits you if you specifically want a full blood count with a differential and ESR, and you are happy to test with Better2Know regardless of price. It is a narrower option than most of its peers, so it is not the best fit if you want the broadest possible general health check.
If cost or depth matters more, Monitor My Health's Essential Health Screen (£49) covers the same 9 markers for far less, and Blue Horizon Medicals' Fingerprick Wellman or Fingerprick Wellwoman tests (£82.25) cover 20 markers each. Better2Know's own £79.95 Complete Blood Chemistry Test Nurse Kit also tests more (10 markers, including organ profiles) for around half this price.
You give a venous blood sample at a Better2Know clinic or during a home nurse visit. The sample is analysed for a full blood count with a 5-part differential, individual white cell counts, platelets, red cells and ESR, with results available within around 1 working day. Better2Know does not state that results are reviewed by a doctor as standard, though it recommends discussing any abnormal results with a doctor and can arrange a private consultation.
At £145, this full blood count with a 5-part differential is the most expensive test in its comparison group, despite testing fewer markers than most peers: Monitor My Health's Essential Health Screen matches its 9 markers for £49, and Blue Horizon Medicals' Fingerprick tests cover 20 markers for £82.25. It's priced 28% above the group's £113 median, and results are not reviewed by a doctor as standard.
