Blood Film Examination

A Blood Film Examination looks at the size, shape and number of your red cells, white cells and platelets under a microscope. It's commonly used to investigate unexplained fatigue, bruising or an abnormal full blood count rather than as a routine check.

About this test

A Blood Film Examination involves spreading a thin smear of your blood on a slide, which a trained laboratory professional then examines under a microscope for the size, shape and number of red blood cells, white blood cells and platelets. It is commonly used to look into symptoms such as unexplained fatigue, bruising or frequent infections, or to follow up an abnormal full blood count.

We do not have a directly comparable rival test on file for this specific examination, so we cannot compare it against named peers. Within the wider set of general wellness tests we track, it is priced above the typical rate, at 19% over the median for tests of a similar size.

The test scores well for clarity, since the description, sample type and turnaround are all published clearly, and reasonably for collection convenience, with both a clinic draw and a home nurse visit offered. It loses marks on clinical depth, because it is counted as a single test rather than a multi-marker panel, and on results and follow-up, since a doctor does not review the findings as standard.

Who is it for?

This suits you if a GP or a previous blood test has flagged an abnormal full blood count, or if you have symptoms such as unexplained fatigue, easy bruising, frequent infections or pale skin that you want investigated further. It is a specialist follow-up test rather than a general wellness check.

We do not hold a directly comparable rival test on file, so if you are looking for this specific examination it is worth checking directly with other providers on price. Better2Know's own description notes this test is often used to follow up an abnormal full blood count, so you may want that test first if you have not already had one done.

How it works

A trained healthcare professional takes a venous blood sample at a clinic, or via a home nurse visit, and a thin smear is prepared, stained and examined under a microscope. Results, which detail any abnormalities in your red cells, white cells or platelets, are ready within one working day of the sample reaching the lab; the provider does not state that a doctor reviews them as standard.

Pros & cons

Pros

  • Examines red cells, white cells and platelets individually under a microscope.
  • Turnaround is one working day once the lab receives your sample.
  • You can have the sample taken via a home nurse visit instead of a clinic.
  • Useful specific follow-up if a full blood count has already flagged an abnormality.

Cons

  • Priced above the typical rate for the general wellness tests we track (+19%).
  • A doctor does not review your results as standard.
  • Best used as a follow-up test rather than a first, standalone check.
