The leukocytes formula or leucocitaria it measures the present percentage of every type of leukocytes in the whole of white globules. On having increased a group of leukocytes, a percentage diminishes the being other, although sometimes only there exists an increase or decrease of a concrete type and for it alone the percentage offers an evaluation orientativa but it owes to tell the entire number of every group to know what is the variable to be taken into consideration and to be studied. There are different groups of white globules, the called polimorfonucleares (neutrófilos, eosinófilos and basófilos) and the mononuclear ones (lymphocytes and monocitos). The leukocytes neutrófilos are the most numerous and in percentage terms more significant that they are. His function is the fagocitosis that is understood as if it was an absorption and digestion of strange substances (bacteria, strange bodies, woven etc...). The immature forms that appear when there is a fundamental intense stimulus for his production are called crooks (for the form of the nucleus); it usually indicates the existence of intense activity of the defenses against infections for bacteria. The leukocytes eosinófilos are called this way by the red color in which they appear to the microscope by a coloring with eosina. They are usually raised in certain illnesses caused by allergy or by parasitic infections. The basófilos usually have a similar behavior. The mononucleate leukocytes are the lymphocytes and the monocitos. They have the only and small cellular nucleus. His functions are them to fight chronic viral and bacterial infections. The modification of the percentage of leukocytes can face to the diagnosis of infectious, inflammatory illnesses, and other processes. When in the leukocytes measurement young cells are seen the neutrófilos appear in the shape of nucleus in the shape of cane (crooks), and an increase of the percentage of the white globules polimorfonucleares. this is named like "left shift". This term suggests sharp bacterial infections. The "right shift" is said when the percentage of lymphocytes and monocitos encuantra increased with regard to that of the polimorfonucleares (neutrófilos, eosinófilos and basófilos), it collaborates in general to viral illnesses. The eosinofília, which is the increase of the percentage or of the entire number of eosinófilos, he suggests an allergic picture or a parasitic infection. The leukocytes inventory is usually realized in a study of hematimetría and inventory leucocitario finished. To realize this analysis to be on an empty stomach is not needed. It is possible to realize the capture in an appropriate place (consultation, clinic, hospital) but sometimes it is realized in the proper domicile of the patient. To realize the capture it is needed of locating an appropriate vein and, in general, there are used the veins placed in the flexura of the elbow. The person entrusted to take the sample will use sanitary gloves, a needle (with a syringe or pipe of extraction). It will put a tortor (tape of gum - latex) in the arm so that the veins retain more blood and turn out to be more visible and accessible. It will clean the area of the prick with an antiseptic one and by means of a palpación it will locate the appropriate vein and will gain access to her with the needle. They will release the tortor. When the blood flows for the needle the sanitary one will realize an aspiration (by means of the syringe or by means of the application of a pipe with gap). On having finished the capture, it extracts the needle to itself and the area is pressed with a cotton or similar torunda to favor the coagulation and it will indicate him to itself that flexione the arm and the area pressed with a Band-Aid supports for some hours.
