DENOMINATION

• Amilasa,
• Amilasa sérica,
• Amilasa in whey.

DEFINITION

The amilasa is an enzyme that has the function to digest the glicógeno and the starch to form simple sugar, she takes place principally in the glands you will salivate and in the pancreas. When one of these glands inflames apportionment the amilasa to the blood and his level turns out to be high in the analysis of the amilasa sérica.

WHY IS THE ANALYSIS REALIZED?

It is used to evaluate the function of the pancreas, to diagnose the presence of illnesses of the same one and to control his evolution. Also it is used to evaluate illnesses of the biliary vesicle (stones ó litiasis), intestinal problems, and other diverse illnesses.

The amilasa sérica turns out to be set sail at 12 a.m. of an injury of pancreas to return to the normality to the 48 at 72 hours. If he persists high the fact is that the problem has not been solved.

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 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.

The abstracted blood moves to the analysis laboratory in a special pipe for biochemistry, which contains an anticoagulant product. In general more than 10 milliliters of blood are not usually necessary for a standard battery of biochemical parameters.

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.

Normal levels of Amilasa in whey: from 30 to 220 U/L.

In these values there can be differences for the skill or for proper criteria of normality of concrete laboratories, sometimes in the status of values and other times for the units to which one alludes. This way they can be given like normal status between 40 to 140 U/L.

EVALUATION OF ABNORMAL RESULTS

The developing Amilasa levels in the blood can indicate:

• Cancer of pancreas, ovaries, lung.
• Colecistitis.
• Colic of biliary vesicle.
• I embarrass ectópico with break of horns.
• Intestinal obstruction.
• Sharp Pancreatitis.
• Problems of obstruction of biliary or pancreatic conduits.
• It ulcerates of stomach perforated.

The diminished Amilasa levels in the blood can indicate:

• Pancreas cancer.
• Pancreatic injury.
• Renal illnesses.
• Toxemia in the pregnancy.
