DEFINITION
It is an analysis that is realized separately or in a general biochemist request in the blood. Present measures the quantity (concentration) of creatinina in the blood. The creatinina is the result of the degradation of the creatina, which is a component of the muscles. The creatinina can be transformed into ATP that a source of high energy for the cells. The creatinina production depends on the modification of the muscular mass, and it changes little and the levels are usually very stable.
WHY IS THIS STUDY REALIZED?
It is a parameter that indicates the renal function.
SKILL OF ACHIEVEMENT
To realize this analysis it is needed to be on an empty stomach at least 6 hours earlier. 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.
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 IN THE BLOOD
The normal values in the adult men are between 0,7 and 1,3 mg for deciliter. In the adult women between 0,5 and 1,2 mg by deciliter In the small children values of 0,2 and 1 are accepted mg/dl. The values more high of 4 mg/dl owe to an important renal mistake.
POSSIBLE DIAGNOSES IN ABNORMAL VALUES
The creatinina raised in blood can appear in:
- Acromegalia
- Dehydration
- Muscular dystrophy
- Eclampsia
- Glomerulonefritis
- Diabetic Nefropatía
- Renal obstructions (stones, tumors)
- Pielonefritis
- Cardiac problems
There can turn out to be the creatinina diminished in:
- Advanced muscular dystrophy
- Miastenia gravis
