- Saturation of Transferrina,
- Capacity of reception of the iron and the transferrina.
The Transferrina is a protein of the group of the globulins that receives the iron of the diet, it accumulates it and transports, constituting the principal fixing protein of circulating iron.
WHY IS IT REALIZED?
The CTCH (aptitude of reception of the iron and the transferrina) measures the quantity of proteins that fix the iron for it on having measured both things we are reflecting the same.
In contrast to the ferritina that what it does is to fix the iron of the deposits and not the circulating one.
When there is an absence of iron the CTCH will turn out to be high.
The transferrina also can be used like factor reactant of sharp phase but in this negative case, since it diminishes his value in chronic, inflammatory, infectious illnesses and in the cancer. On the other hand in the pregnancy it turns out to be high.
The diet with more or less iron does not modify the values of the transferrina or of the CTCH, since it reflects a functioning of the liver that is the producer of the transferrina, also it reflects the nutritional state in proteins of the patient.
The saturation of the transferrina is calculated by means of a formula:
||I shoe sérico entirely
|| x 100
The value of the percentage saturation is 20 to 50 %. It can descend from 15 % in the anemia ferropénica, and rises in the anemia hemolítica, sideroblástica, and megaloblástica.
Also she turns out to be raised in the poisoning or excess of ingestion of iron, since the iron increases but not this way CTCH, and the percentage of saturation will turn out to be very high.
In the chronic illnesses there appear low levels of iron, of the CTCH and the saturation will be normal.
SKILL OF ACHIEVEMENT
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
NORMAL VALUES OF CTCH, TRANSFERRINA AND SATURATION OF TRANSFERRINA IN WHEY
- 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 levels of CTCH
||from 250 to 460 µg/dl
|Normal levels of Transferrina
|in adult men
||from 215 to 360 mg/dl
|in adults women
||from 245 to 370 mg/dl
|in children younger than 1 year
||from 125 to 270 mg/dl
||from 200 to 350 mg/dl
|Normal levels of Saturation of the transferrina
||of 20 to 50 %
||of 15 to 50 %
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.
EVALUATION OF ABNORMAL RESULTS
The developing CTCH levels can indicate:
- Contraceptive oral
- Anemia ferropénica
The diminished CTCH levels can indicate:
- Lacking in proteins
- Inflammatory illnesses
- Hepatic cirrhosis
- Anemia hemolítica or pernicious
