 OTHER NAMES
- Magnesium in blood,
- Mg in blood,
- Magnesium sérico.
DEFINITION
The Magnesium is a useful ion in different functions of the human body, it is inside the cells and especially in the bony textile. It is joined largely to the molecules of ATP that has a very important role in the route of the fosforilación (that is one of the principal routes of production of energy of the human body). For it the Magnesium is fundamental so that the textiles work, especially in muscular textiles and for it it is important to value the function of the muscular textile and of the cardiac one. The relation of the content of Magnesium, potassium, and the calcium at cellular level is fundamental for the balance and cellular stability. The diminished magnesium levels can produce an annoyance of the cardiac textile and for it to produce arrhythmias, and on the contrary an increase of the same one alters the conduction of cardiac stimuli, producing debts in the polarization and stimulation of the cardiac contraction (it lengthens the spaces PR, QT and QRS of the electrocardiogram).
:PARA WHAT IS REALIZED?
The changes of concentration of the Magnesium in the blood produce problems of the cardiac rhythm (arrhythmias, blockades), muscular weakness, irritability, muscular contractions, convulsions, etc... The magnesium excess can produce digestive symptoms as morning sickness, vomiting, weariness and alteration of the speech.
The absence of magnesium usually owes to an inadequate diet, or for a general malnutrition, the excess can owe to the capture of antacids that contain magnesium in excess.
PROCEDURE OF SECURING
To realize this analysis it is needed to be on an empty stomach at least 6 hours earlier. The medicines can alter the values of magnesium for the thyroid gland, the antacids, the laxatives, and some diuretics and antibiotics. 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 MAGNESIUM IN WHEY
| Normal levels of Mg in whey in adults |
1,3 to 2,1 mEq/l |
| Normal levels of Mg in whey in children |
1,4 to 1,8 mEq/l |
In these values there can be very small 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 Magnesium levels in the blood can indicate:
- Renal illnesses
- Diabetes without control
- Illness of Addison
- Hipotiroidismo
- Antacid medicines with magnesium
The diminished Magnesium levels in the blood can indicate:
- Malnutrition
- Alcoholism
- Renal illnesses
- Diabetes
- Intestinal Malabsorción
- Hipoparatiroidismo.
