OTHER NAMES

• Measurement of the speed,
• VSG,
• Sedimentation speed eritrocitaria.

DEFINITION

It is the precipitation of the eritrocitos (red globules) in a certain time (1-2 hours), which is related straight to the tendency of the red globules towards the formation of accumulations (batteries of coins) as well as to the plasmatic concentration of proteins (globulins and fibrinógeno).

The analysis of the VSG is realized normally in a finished hematimetría study.

WHEN DOES IT RISE?

If the proteins of the group of the globulins are raised by it with regard to the albumin the speed rises. Also a high fibrinógeno proportion can provoke this elevation.

WHY DOES IT MEASURE ITSELF?

The principal uses of the measurement of the VSG are:

1. To detect inflammatory or infectious processes. As discriminator or reactant of presence of illness.
2. As control of the evolution of certain chronic illnesses ó infectious.
3. To detect secret inflammatory chronic processes or tumors.

In the first months of pregnancy it can turn out to be high without much ado aftereffects.

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.

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. 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 POSBLES 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.

In the normal blood the eritrosedimentación speed is practically void, inclusive if the cholesterol or other lípidos are very high it can diminish the aptitude to form accumulations and to diminish more the VSG.

More discriminatory utility:

If his value is major than 100 mm / hour it is necessary to think that a problem of cancer exists, colagenosis, rheumatic illnesses, and other chronic infectious illnesses.

ABNORMAL RESULTS

The VSG rises in:

• Intense anemia
• Rheumatoid arthritis
• Renal illnesses
• Autoimmune illnesses (Lupus eritematoso)
• Thyroid illnesses
• Pregnancy
• Rheumatic fever
• Sharp infections
• Macroglobulinemia
• Multiple Mieloma
• Rheumatic polymyalgia
• Syphilis
• Tuberculosis
• Vasculitis

The VSG can turn out to be diminished in:

• Proteins descent in the plasma (for hepatic problems ó renal)
• Decrease of the fibrinógeno
• Cardiac mistakes
• Policitemia
