What is Albumin Quantitative?

Quantification of Albumin in the blood is one of the important tests in biochemical tests when checking health. People who are suspected of having liver disease, multiple myeloma, kidney disease, poor health, etc. are usually assigned to perform a quantitative serum Albumin test.

Albumin is one of the most important protein components of serum, accounting for 58-74% of the total protein content. 40% of albumin is in plasma and 60% in extracellular fluid. Blood albumin has many important functions such as:
Maintaining colloidal osmotic pressure in the blood, keeping water from leaking out of the blood vessels; Provide amino acids for protein synthesis in the periphery; Responsible for binding, transporting a number of substances produced in the body's metabolism such as fatty acids, bilirubin, steroid hormones and other active substances,... throughout the body. The liver is the only organ in the body that produces Albumin (every day the liver produces about 10.5g of Albumin). Also, the Albumin index clearly shows the functional status of the liver. Albumin decreases when the liver is weakened in people with kidney disease, shock, malnutrition, inflammation,... High blood albumin when the body is dehydrated. However, because the breakdown time of Albumin is from 12 to 18 days, in the early stages of liver damage, it is possible that Albumin in the blood has not decreased much.

Albumin protein test is a test of albumin levels in the blood, used to support the diagnosis of various diseases or to monitor the health status and progression of each patient. In addition, the albumin blood test results also help doctors continue to monitor, prescribe testing methods and prescribe appropriate drugs to treat the disease more effectively.

Doctors order Albumin test and some other tests when a person has signs of liver dysfunction such as fatigue, rapid and rapid weight loss, jaundice or symptoms of nephrotic syndrome such as swelling around the eyes, abdomen and ankles; Doctors only perform blood Albumin and Prealbumin tests when they want to monitor and check the nutritional status of a patient. Albumin concentration does not change as rapidly as Prealbumin but it can decrease, reflecting protein deficiency and malnutrition; Test plasma albumin concentration to assess the patient's liver and kidney function.

Forcing the garo for a long time can increase the Albumin index when testing; Taking a blood sample near the site of the infusion may result in a lower than actual level of Albumin; During pregnancy, the blood albumin concentration in the blood decreases, the globulin concentration increases; Using drugs that increase Albumin levels: Anabolic steroids, anti-inflammatory drugs containing steroids, dextran, androgens, growth hormone supplements, insulin, progesterone and phenazopyridine,... Using drugs to reduce Albumin levels: estrogen, ammonium ion supplements, hepatotoxic drugs and oral contraceptives; Patients who are dehydrated often have elevated albumin levels.

5.1 Before the test The patient informs the doctor about the drugs he is taking so that the doctor can consider and stop using the drug before taking blood for testing; When doing the test, the patient should wear a short-sleeved shirt so that the nurse can easily draw blood from the arm. 5.2 Testing procedure With blood test: The examiner will wrap a bandage around the patient's arm to stop the blood circulation, disinfect the injection site with alcohol, inject a needle into the vein, more than 1 injection can be given. times if necessary, attach a tube to drain the blood and remove the bandage around the arm after enough blood has been drawn. Finally, the medical staff applies a cotton ball to the injection site and puts a bandage on it. Note: the patient draws blood in the morning, on an empty stomach. With urinalysis: Patients are instructed to collect urine within 24 hours, to avoid fecal contamination of urine, to not mix toilet paper with samples, and to keep urine samples in the refrigerator for a period of time. 24 hours, last urine collection as close to the end of 24 hours as possible. The patient then transfers the urine sample to the place where the albumin quantification test is performed.

6.1 Normal value Children 0 – 4 months old: Albumin concentration is 2.0 - 4.5 g/dL; Children 4 - 16 months old: Albumin concentration is 3.2 - 5.2 g/dL; Adults over 16 years: Albumin concentration is 3.5 - 4.8 g/dL or (35 - 48 g/L). 6.2 Abnormal values ​​Albumin quantification decreased: Due to liver disease (alcohol addiction, hepatitis, cirrhosis), diabetes, kidney disease, shock, malnutrition, inflammation, especially after surgery. Health conditions such as burns, protein-losing intestinal disease, urinary tract disease, Hodgkin's lymphoma, hypothyroidism, heart failure, multiple myeloma, autoimmune disorders such as lupus erythematosus or Rheumatoid arthritis, ... can also reduce the concentration of Albumin in the blood, even when the patient eats enough protein; High albumin: Due to dehydration, acute pancreatitis, pregnancy, high protein diet, long garnage or recent blood donation or blood test. Quantitative serum albumin is an important indicator to help doctors accurately diagnose the pathology of each patient. Therefore, in case there are symptoms of liver, kidney or damage to these organs, patients should go to reputable medical centers to perform a quantitative albumin test. The purpose of the Albumin index test is to accurately diagnose the cause and provide timely and effective treatment.
