Differential blood count with smear

Smear morphology – what is it?

Smear morphology is the most important and basic diagnostic test. It involves measuring the number of individualcells in the blood and measuring other parametersof the blood.

Human blood consists of a morphotic part (where blood cells, platelets and other cellsrs are located) and plasma. Most often, the number of individual cellsre examined automatically (by a hematology analyzer). The addition „5 Diff ” means that during the counting leukocytes will be divided into 5 groups: neutrophils, basophils, eosinophils, monocytes and lymphocytes. There is also a type of „3 diff” whichry divides them into only 3 groups. A smear, on the other hand, is the part of the test thatra is performed by a qualified laboratory technician and instructs on microscopic evaluation of the size and quality of individual cellsrecords.

Morphology with smear – when to perform the test?

As this is the most basic test thatre nevertheless provides a lot of valuable information it is ordered as part of virtually every blood test.

Most diseasesb will affect specific parameters and the number of given blood cells in the bloodstream, hence changes in the morphological evaluation can be the start of the diagnosis of a disease of virtually any system. Morphological examination is also performed for prophylactic purposes, since many diseases, before showing symptoms discernible to the patient, are manifested by changes precisely in the results of this examination.

The examination morphology with smear includes the measurement of the following parameterss:

• hemoglobin concentration
• hematocrit
• platelet count
• number of leukocytesw (divided into the 5 populations mentioned above)
• number of erythrocytesw
• red cell indices: MCV – mean red cell volume, MHC – mean hemoglobin mass in red cell, MCHC – mean hemoglobin concentration in red cells

Morphology with smear – who should perform?

Smear morphology is performed as a prelude to the diagnosis of many diseasesb, which can produce many different symptomsb. Any worrisome symptoms should be reported to a doctor, whory can then order additional tests. Some of the only reasons to order a blood count are suspected diseases such as anemia, infections, inflammation, cancer and many, many others.

Measurements of red blood cells (and their indices enable the diagnosis of disorders associated with anemia, otherwise known as anemia. The division of leukocytesinto 5 subgroups is effective in determining a more accurate sourceof symptomsof infection and a preliminary determination of its etiology and whenit is currently. Blood parameters are also a very important tool in monitoring the treatment of hematologic diseasesb and in correcting many nutritional deficiencies.

Certainly, symptomslated should not be ignored, as they can result from the development of many dangerous diseasesb, including cancer. These types of symptomsve include:

• general deterioration of mood
• permanent fatigue
• sleeping problems
• unexplained weight loss
• pallor of skin coverings
• faster fatigue
• sensation of shortness of breath after minor exertion
• dizziness
• fatiguel pain, localized in different parts of the body

Morphology with smear standards

Each of the parametersl examined during this diagnostic test has separate norms. These values rre depending on the patient's age, gender and the local reference rangesre used by the laboratory in question.

Interpretation of the resultss should always be carried out with a doctor, since certain values may be normal for one patient, while in another they will already represent a pathology thatra requires treatment. This depends on the current state of the patient's health, the co-b of other aggravating diseasesb and the goal of the treatment being carried out.

Regular performance of blood counts is able to prevent the development of many diseases which, if not diagnosed early enough, can pose a serious threat to the patient's life.
