In today’s information, we will talk about Bilirubin Test, what are the types of Bilirubin Test, what is the normal range of bilirubin test, why is the bilirubin test done and what are the systems that seem to have increased bilirubin bilirubin We will know all these things in this information when it is considered to be joint.
What is Bilirubin
Bilirubin is a yellow colored substance formed by the breakdown of RBCs into haemoglobin. That is, the more RBCs in your blood are broken down, the more the amount of bilirubin will increase.
Because the RBC in our blood does not survive for a long time, its life cycle is 100 to 120 days, then it breaks down after 100 to 120 days, that is, it dies and in its place a new RBC is formed.
What is Bilirubin Test?
Bilirubin test measures the level of bilirubin in the blood. The amount of bilirubin in our blood is detected. And if the amount of bilirubin in our body ie blood increases, then jaundice is considered as jaundice.
But there are many other diseases other than jaundice, such as liver, cirrhosis, hepatitis, anemia or bile duct stone, the amount of bilirubin also increases.
In which symptoms bilirubin test is done?
- yellowing of the eyes or yellowing of the skin
- stomach pain or loss of appetite
- vomiting or nausea
- Yellow urine or dark brown stools
- hepatitis or liver cirrhosis
- anemia
There are three types of bilirubin test done.
- Indirect bilirubin (unconjugated)
- Direct bilirubin (conjugated)
- Total bilirubin
What is meant by conjugated, unconjugated and total bilirubin?
When RBC breaks down, unconjugated bilirubin is formed, then first it binds with a protein, which we call unconjugated bilirubin. And when it goes to the liver and is separated from the protein and combined with sugar, it is called conjugated bilirubin.
With the help of the test, we can know how much is unconjugated and conjugated bilirubin, adding these two quantities gives us the total bilirubin.
Why is the Bilirubin Test Done?
- This test if the doctor suspects that the patient has some liver related problem.
- You have a yellowish look somewhere in your body
- or yellowing of the eyes
- or swelling in the body
- or itchy
- So if the doctor thinks that the bilirubin has increased due to an infection
So if all these problems occur, doctors refer you for Bilirubin Test.
How is the Bilirubin Test Done?
This test requires a blood sample which is taken from the patient’s side. For this test, the patient’s blood sample is taken.
Are any special precautions required before this test?
No special precautions are required before this test, this test can be done at any time according to the convenience of the patient.
What is the normal amount of bilirubin?
- For unconjugated bilirubin, 0.2 to 1.2 mg/dl is considered normal.
- 0 to 0.3 mg/dl is normal for Conjugated Bilirubin.
- and goes up to 1.4mg/dl for Total Bilirubin.
But these values can be slightly up or down according to different laboratories.
What can be the reasons for increased bilirubin
There can be many reasons for the increase in bilirubin.
- Liver disease such as hepatitis, cirrhosis increases bilirubin
- Blood diseases such as hemolytic anemia also increase bilirubin in
- Apart from this, if you have stones in your gallbladder, bilirubin can also increase due to these reasons.
What are the causes of increased bilirubin in young children?
- In young children, the blood is formed due to the deficiency of hemoglobin or the disease occurs due to the defect of hemoglobin.
- Apart from this, bilirubin can also increase in erythroblastosis fetalis.
