WHAT IS STUDIED?

In a routine hematimetría study they go to quantify and evaluate different cellular groups, the red globules (red blood corpuscles), the white globules (leukocytes), the thrombocytes, the content of hemoglobin, and other parameters related to his quantity, form and content.

VALUES THAT ARE STUDIED

Parameter Normal values
Number of red blood corpuscles 4 - 5,5 millions / ml
Hemoglobin 12 - 16 g/dl
Hematocrito 37-52 %
VCM 80 - 99 fl
HCM 27-32 pg
CMHC 32-36 g/dl
Thrombocytes 135-450 thousands / ml
VPM 9,6 fl
Number of Leukocytes 4,5-11 thousands / ml
Neutrófilos 42 - 75 %
Lymphocytes 20.5 - 51.1 %
Monocitos 1.7 - 9.3 %
Eosinófilos 0-1 %
Basófilos 0-0.2 %

WHY IS IT REALIZED?

  1. The red blood corpuscles quantity can offer information of health or of the presence of an anemia, general illnesses, or different types of cancer. As the red blood corpuscles are the managers of transporting the hemoglobin (protein that carries the oxygen to the textiles), his decrease produces weariness and fatigue sensation.
  2. The hemoglobin concentration will offer us complementary information on the possible alteration of the number of red blood corpuscles.
  3. The hematócrito, is the percentage of the mass of the eritrocito in relation to the blood volume. With this information the indexes are calculated hematimétricos (VCM, HCM, VMHC). The alteration of these parameters they will help us to face different illnesses that cause alterations in these indexes (Example: different types of anemias)
  4. The white globules (leukocytes) are the managers of the defenses of the person, by it in infection pictures they are increased, or in certain illnesses they are diminished. Also it is an important knowledge who are the populations of every type of leukocytes, by it in the results the neutrófilos appear, monocitos, lymphocytes, basófilos and eosinófilos. According to the results of each of these populations it can face towards one or another illness.
  5. The thrombocytes are the cells entrusted on behalf of the coagulation by it if his number diminishes there can appear (bled) pictures of hemorrhages that it can owe to itself to different problems and illnesses, and his number increases in different rheumatic or autoimmune illnesses.

Each of these values can offer major information; for it we will gather each of them separately.

PROCEDURE OF SECURING

  1. To realize this analysis to be on an empty stomach is not needed.
  2. 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.
  3. 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).
  4. 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.
  5. 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.
  6. 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).
  7. If several samples are needed for different types of analysis blood will be extracted to him more or less or different gap pipes will be applied.
  8. 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

  1. The securing by means of a prick of the vein can produce certain pain.
  2. The possible difficulty in finding the appropriate vein can give place to several pricks.
  3. Appearance of a haematoma (bruise or cardinal) in the extraction area, 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.
  4. 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.
