 OTHER NAMES
- Ferritina in blood,
- Anemia study.
DEFINITION
The ferritina is the principal protein of storage of iron in blood, and it is proportional to the iron deposits. It usually realize this analysis in the context of a study of anemia together with the iron sérico, the transferrina saturation, and other values hematimétricos (Red blood corpuscles, Hemoglobin, Hematocrito, VCM, HCM, CHCM, etc...). In the normal persons the value of 1 ng/ml of ferritina corresponds to 8 mg of stored iron.
¿PARA WHAT IS REALIZED?
It is used to evaluate the presence of an anemia and indicates the quantity of available iron of the organism. When the values of the iron are obtained sérico entirely and the capacity of reception of iron is a part of the study of an anemia. Also reactant of sharp phase can turn out to be raised like factor rising in inflammatory illnesses, infections, alcoholism, uremia, colagenosis and in the cancer. In general the low values of ferritina are accompanied of low iron levels, or of the size and chromatism of the red blood corpuscles. The pregnancy and another situation with diminished values of ferritina On the contrary when it is raised the poisoning collaborates at high levels of iron that appears in accumulation illnesses like the hemocromatosis, hemosiderosis ó for iron. Also she turns out to be raised in patients with anemia megaloblástica, hemolítica, and some chronic hepatic illness. It is used for the control of the deposits of iron in the chronic renal insufficiency.
PROCEDURE OF SECURING
To realize this analysis to be on an empty stomach is not needed. The ferritina can turn out to be high with the recent transfusions and with meals or medicines with iron excess. 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
- 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, 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.
NORMAL VALUES OF FERRITINA IN WHEY
| Normal levels of Ferritina |
| in adult men |
from 12 to 300 ng/ml |
| in adults women |
from 10 to 150 ng/ml |
| in children younger than 1 year |
from 25 to 500 ng/ml |
| in children |
from 7 to 142 ng/ml |
In these values there can be certain 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. Sometimes the units offer themselves in µg/l ó units IF.
