Lipoprotein X (LP-X)

Lipoprotein-X is a special lipoprotein that occurs in obstructive jaundice and is present in low-density lipoproteins, which may be involved in phospholipid reflux in bile. Determination of serum lipoprotein-X is helpful in identifying jaundice and can be used to understand the severity of cholestasis.

Applicable gender: whether men and women apply fasting: fasting

High results may be diseases: liver cancer, gallstones, primary biliary cirrhosis, duodenal diverticulum obstructive jaundice syndrome

First, the precautions before blood draw

1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results.

2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results.

3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection.

Second, should pay attention after blood draw

1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma.

2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended.

3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.

4. If there is localized congestion, use a warm towel after 24 hours to promote absorption.

3. Please inform the doctor about the recent medication and special physiological changes before the test.

Inspection process

Adverse reactions and risks

1. Infection: Pay attention to aseptic operation when collecting blood, avoid contamination of water and other parts at the blood collection site to avoid local infection.
2, bleeding: after the blood is given a full compression time, especially coagulopathy, bleeding tendency, to avoid local subcutaneous oozing, bruising and swelling.
