TO CONSULT

White globules,

Leukocytes measurement,

Leukocytes account.

DEFINITION

The leukocytes or white globules are cells that are principally in the blood and circulate along her with the function to fight the infections or strange bodies; but sometimes they can attack the normal textiles of the proper body. It is a part of the immune defenses of the human body.

There are called white globules since this one color is that of his aspect to the microscope.

There are different groups of white globules: the called polimorfonucleares (neutr�filos, eosin�filos and the bas�filos) and the mononuclear ones (the lymphocytes and the monocitos).

The origin of all the forms of leukocytes is from cells mothers of the bone marrow.

WHY IS HIS STUDY REALIZED

The modification of the quantity of leukocytes can face to the diagnosis of infectious, inflammatory illnesses, cancer and leukemia, and other processes. For it the inventory is much orientativo in different illnesses. Also the percentage of every group of leukocytes will offer us a major information to need a diagnosis.

When in the leukocytes measurement young cells are seen the neutr�filos 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 deviation "to the left". This term suggests sharp bacterial infections.

The study of the leukocytes is usually realized in a study of hematimetr�a and inventory leucocitario finished.

PROCEDURE OF SECURING

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 palpaci�n 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.

PROBLEMS AND POSSIBLE RISKS

The securing by means of a prick of the vein can produce certain pain.

The possible difficulty in finding the appropriate vein can give place to several pricks.

Appearance of a haematoma (bruise or cardinal) in the extraction area; it is due usually to the fact that the vein has not closed well after the later pressure and blood has kept on going out producing this problem. Type Hirudoid can apply an ointment to itself � or Trombocid � in the area.

Inflammation of the vein (phlebitis); sometimes the vein turns out to be shaken, well be for a cause merely physically or why it has become infected. It will have to support the relaxed area a few days and type Hirudoid can apply an ointment to itself � or Trombocid � in the area. If the problem persists or appears fever will have to consult it with his doctor.
