Abstract

Background: In medical patients, the single most common investigation is carried out by means of the full blood count (FBC). This is very helpful in providing information for diagnosis and management, if interpreted carefully and in relation to clinical history. Primary hematological disorders by abnormalities in FBC are often beware by doctors.
Method: We performed hematology laboratory from May 2019 until October 2019 in all of patient who administered in Udayana University General Hospital. From the recruited participants who were directly collected data demographics and information about drug history.
Results: In present study out of 450 cases, 205 (45.6%) were males and 245 (54.4%) were females. It was found from different department, 71% from general practitioner, 14.5% from internal medicine, 6.9% from obstetric and gynecology department, and 4.9% from pediatric department. We found 7.1% cases of anemia, 34.9% cases of leukocytosis, 9.8% cases of leukopenia, and 16.9% cases of thrombocytopenia.
Conclusion: Important information sourced from FBC can help doctors in patient diagnosis and management. In relation to diagnosis, surgical intervention and drug treatment it is very important to value not only the current lab results but also to assign potential trends over time.
