Cytology is a fast, non-invasive technique that leads to a diagnosis in most cases. Some of the indications for taking samples for cytological study include a presence of masses or neoformations in any external or internal location indicated by ultrasound or CT scans, a change in echogenicity, an organ presenting loss of architecture, effusion in cavities, etc. As the responsibility for passing on relevant images of the case falls to the veterinarian in the clinic and may require experience, a full physical assessment of the preparations is always preferable. However, a remote diagnosis can be a good first port of call if the images sent are representative of what is in the preparationsneoformaciones
Although, in some cases, a definitive diagnosis may be possible, the aim in most cases should be:

Find out the keys to take good diagnostic images before referring a cytology case.
For a case to be diagnosed successfully, samples must be representative and meaningful images of these samples must be taken.
In the case of masses/nodules, it is important to redirect the needle in various directions to obtain cells from different areas of the lesions. In large legions, it is best to avoid the middle area, as this may only provide necrotic material. Aspiration is to be avoided in most cases, especially in internal organs or in highly vascularised lesions that bleed easily. If no material is obtained on the first attempt, aspiration may be used on the second. It is important to smear the sample gently on a microscope slide (avoiding splattering) and stain it properly to keep as many cells as possible intact without producing an overly thick preparation and so that the colours distinguish the different structures in the images.
You might have the perfect sample, but it counts for nothing if the images taken of it are unsatisfactory and cannot be used for diagnosis. Here is our advice for taking the ideal images:
