Although the findings from the test do not give a conclusive diagnosis, these findings are quite sensitive in detecting parasitic infections. The test offers direct visuals of these parasites within our blood cells. They typically include a description of how your blood cells look. Any abnormalities in the appearance of your blood cells only indicate the presence of an underlying condition. Hence after your test, a doctor should interpret your report, and based on the case, the doctor may or may not recommend more testing.
A peripheral blood smear test is considered normal when your blood cells have a normal appearance and are sufficient in number. A peripheral blood smear test is considered abnormal if there are abnormalities in size, shape, colour, or number of cells in your blood. Abnormalities depend on the type of blood cell affected.
Disorders related to red blood cells include
- Iron-deficiency anaemia, where the body does not produce sufficient red blood cells due to iron deficiency.
- Sickle cell anaemia occurs when red blood cells have an abnormal shape.
- A hemolytic uremic syndrome is triggered by an infection in the digestive system.
- Polycythemia rubra vera
Disorders related to white blood cells include:
- Acute or chronic leukaemia
- Hepatitis C infection
- Fungal infections
- Parasitic infections
- Multiple myeloma
Disorders that affect platelets include:
- Thrombocytopenia occurs when the number of platelets is very low due to an infection or other diseases.
- Myeloproliferative disorders are a set of disorders that can cause the blood cells to grow abnormally in the bone marrow.
A blood smear test can also indicate other medical conditions, including:
- Kidney disease
- Liver disease
Once you receive the results, consult your doctor, who can diagnose your condition and initiate your treatment.
