Blood film microscopy
A blood film is a thin layer of your blood spread on a glass slide, so the cells can be looked at one by one under a microscope. I review every film myself, which means you get a consultant's eye on your blood cells, not just a set of numbers from a machine.
Seeing what the numbers can't tell you
A routine blood count tells us how many cells there are. It doesn't show what they look like. When I examine your blood film under the microscope, I can see the size, shape and appearance of each type of cell, and spot small changes an automated analyser can miss.
For many people, a blood film is an important first step. It can help explain an unexpected result, point towards a likely cause, and show whether further tests are needed at all, so you aren't put through investigations you don't need.
If you've been told a recent blood test came back abnormal, my page on abnormal blood test results explains what those results can mean and how I can help.
What a blood film can show
-
Red blood cells
Their size, shape and colour, which can give clues to causes of anaemia such as low iron or vitamin levels, or other blood conditions.
-
White blood cells
Whether the different types look normal and mature, or whether there are unusual cells that need a closer look.
-
Platelets
Their size and appearance, and whether they are clumping together, which can sometimes make a platelet count look lower than it really is.
Simple for you, careful on my side
There's nothing complicated about having a blood film. Here is how it works.
-
A simple blood sample
A small sample is taken from a vein in your arm, just like an ordinary blood test. It only takes a few minutes.
-
My review under the microscope
A drop of your blood is spread and stained on a slide, and I examine it myself, alongside your other results and your history.
-
Results explained clearly
I explain what I've found in plain language, what it means for you and whether anything further is needed, at a follow-up consultation or in a written results report.
Common questions about blood films
Something else on your mind? Please get in touch with the practice and we'll be happy to help.
Is a blood film the same as a full blood count?
No. A full blood count is done by a machine and measures how many of each cell type you have. A blood film is looked at by eye under a microscope, so I can see what the cells actually look like. The two are often used together.
Do I need to prepare for the blood test?
A blood film doesn't usually need any special preparation. If other tests are being taken at the same time that do need preparation, such as fasting, we'll let you know beforehand.
Will I need more tests afterwards?
Not always. Often the film is reassuring, or gives enough information to plan the next step. If I do recommend anything further, I'll explain why and what it involves, so you can decide together with me.
I'm not sure which appointment I need. What should I do?
That's very common. Please contact the practice and tell us a little about your situation, and we'll help you choose the right appointment.
