The analysis of levels of uric acid in the blood is a study performed separately or in a general request of biochemical blood tests. Measures the amount (concentration) of this uric acid in the blood.
Uric acid is the end result of purine metabolism (parts of DNA and RNA). Most uric acid is excreted by the kidney, and something intestinal system. With increasing tissue destruction (as in various cancers) appears elevated uric acid in the blood, although the most common cause of their increase is gout.
What the analysis is taken
This analysis was done primarily to make a diagnosis of gout, but in certain processes may appear high and is useful for evaluating other diseases.
To perform this analysis is required to fast at least 6 hours prior.
Can you shoot at an appropriate place (consultation, clinic, hospital) but sometimes it is done in the patient’s home.
To make the taking is necessary to locate a suitable vein and, in general, the veins in the elbow are used. The person taking the sample will use sanitary gloves, a needle (with a syringe or tube removal).
- You will have a tortor (tape-rubber latex) in the arm to retain more blood veins and appear more visible and accessible.
- It will clean the area with antiseptic and puncture through a vein located palpation and appropriate access to it with the needle.
- They will release the tortor.
- When blood flows through the needle, aspiration done on health (by syringe or by application of a vacuum tube).
- If multiple samples are required for different types of analysis will be drawn more or less different blood or apply vacuum tubes.
- After the shooting, the needle is removed and the area is pressed with a cotton swab or the like to promote clotting and is instructed to flex the arm and the area pressed with a Band-Aid for a few hours.
Problems and possible risks
- The acquisition by a puncture of the vein can cause some pain.
- The possible difficulty in finding suitable vein can lead to several punctures.
- Appearance of a hematoma (bruise or cardinal) in the extraction zone, usually because the vein has not closed well after the later pressure and has continued to produce blood coming out this problem. You may apply or Thrombocid® type Hirudo ® ® ointment in the area.
- Inflammation of the vein (phlebitis), sometimes the vein is altered, either by a purely physical cause or has been infected. It should be kept relaxed area a few days and can apply an ointment type Hirudo ® ® or Thrombocid® in the area. If the problem persists or fever should consult your doctor.
Uric acid values
Normal values in adult men are between 4 and 8.5 mg per deciliter. In adult women 2.5 to 7.5 mg / dl. In young children values from 2.5 to 5 mg / dl are accepted.
Higher values of 12 mg / dl are considered high (hyperuricemia).
You can modify the values of uric acid and not for a drop certain situations:
- Stress in general can raise uric acid levels.
- The use of radiological contrast also
- Certain products and medications can increase uric acid, caffeine, alcohol, theophylline, etc.
- They can lower uric acid, aspirin, allopurinol, corticosteroids, female hormones.
possible diagnoses abnormal values
It may appear high blood uric acid (hyperuricemia) at:
- Metabolic acidosis,
- Mellitus diabetes,
- Diet rich in purines (red meat, organ meats, sausages, seafood, nuts)
- Eclampsia in pregnancy,
- Kidney failure,
- severe tissue damage (burns, trauma),
- Polycythemia vera,
- Cancer chemotherapy.
- It may appear decreased uric acid (Hypouricemia) at:
- Diets low in purines (proteins),
- Fanconi syndrome,
- Wilson disease.
