CD4 and CD8 are two important white blood cells that are present in the human body. Lymphocytes are a type of white blood cells present in the immune system that conduct the ratio between CD4 and CD8. CD4 cells fight against infection, while CD8 cells help prevent cancer.
The CD4 CD8 ratio test determines how strong your immune system is and how adaptable it is to developing an infection. Let’s know more about the test in detail.
What is the need for the CD4:CD8 Ratio Test?
Some people, after being infected by the Human Immunodeficiency Virus or HIV, unknowingly develop symptoms like flu, and some people show no symptoms at all. So, to confirm this, our healthcare providers advise you to take a CD4 and CD8 ratio test.
The test results mostly show the CD8 and CD4 cell counts. In general, the doctor will focus more on the result of CD4 cell count. This treatment also determines how your HIV treatment is going on.
In a nutshell, the test is needed to check all types of viral infections and other chronic diseases like Lymphocytic leukaemia, as well as some neurological health issues like multiple sclerosis.
What Other Test is Required Along With The Test?
To ensure the immune system is accurate, our healthcare providers will run some other types of tests such as HIV and CBC or Complete Blood Count. These two are the common tests required when you opt for the CD4 and CD8 test. Based on these test results, the next tests or formalities will be done for your treatment.
How Test Results Will Determine Your Health Condition?
After conducting the tests, the result may vary depending on the person’s gender, age, and other health issues, if any. Sometimes, the result varies according to various labs. Although these are not incorrect, if you have any questions, ask your doctor about the test result.
In general, the test result comes with a number per cubic millimetre (number/mm3) or number per microliter. The normal ratio test result is always greater than 1, and CD4 cell count in Lymphocyte blood cells ranges from 500 to 1200/mm3. At the same time, CD8 ranges from 150 to 1000/mm3.
If the CD4/CD8 ratio result value is less than 1, it is called an abnormality. The value defines the following health conditions.
- You may be testing for HIV.
- Can be tested for AIDS if the value is less than 200/mm3.
- Also, if you are related to smoking, then the ratio indicates that you may have Pneumonitis, pneumonia and other cancer-related diseases.
- The number of more white blood cells may lead to Anaemia.
- Other dangerous infections can be hazardous to your life.
- The lower value for some patients indicates that they might have neurological disorders such as Myasthenia gravis and other nerve problems.
In some patient’s cases, the test results exceed the normal range. So, it also indicates that there are some abnormalities in the patient’s health condition. The following health conditions can be taken into account:
- Some chronic infections.
- Some patients might have blood cancers.
- For some patients, it indicates that they might have viral infections.
Understanding The CD4/CD8 Ratio Test:
In traditional methods, the doctors only focus on the CD4 Cell count to understand the responsiveness toward HIV treatment. However, with the development in medical science, the upgradation of HIV testing is currently calculating both CD4 and CD8 ratios.
The formula of this ratio test can be followed as follows:
CD4/CD8 ratio= percentage of CD4 cell count/ CD8 Cell count.
It should always be recommended that the CD4 cell count be greater than the CD8 cell count, and the ratio result should be greater than 1. In general, more CD8 cell counts lead to infections.
- This test helps determine your immune system strength and whether you are at risk when infection arises. These conditions can be compared with some hazardous conditions like Pneumocystis Pneumonia. However, proper medications can probably minimise the situation.
- In case of a low ratio rate it indicates that infections are still in your body and can be treated if they are detected early with proper medications and safety measures. For instance, if you are human immunodeficiency virus (HIV) positive, which is in the early stage, then to bring it into the normal range, it takes up to six years approximately.
- If you are avoiding the test results, then the treatment can’t make your infections curable and may take your life as well.
The Most Common Reason For Abnormal CD4/CD8 ratio test:
The most common reason for an abnormal CD4/CD8 ratio test is testing for HIV positive. Our physicians diagnose these HIV infections by considering other factors, such as Antibody or antigen testing.
After knowing the cause of HIV infection, the physician moves towards the treatment. Before the treatment, he determines the age of infection. If it is newly detected, then this can be curable with certain medications. Otherwise, still today, the chance of survival from AIDs related issues is very low.
Along with medications, the physician determines whether your infection is in a progression state by conducting Viral load tests to ensure the quantity of HIV in your blood. The test is done every six months to check the reduction of the quantity of HIV with the prescribed medicines, or it needs to be changed.
Some Potential Risks While Testing The CD4:CD8 Ratio Test
There are certain risks associated with the testing while using the needle to pull your blood from your vein. The risks include bleeding, infection, or sometimes bruising. If the blood pulling is not done properly, then it can stink your arms or hands for some time, and later, it leads to soring. These situations are very low as professionals do the blood pulling.
Conclusion:
Whether you have some symptoms or you just want to check your CD4/CD8 ratio test, it is allowed in both cases. For a healthier life, this test can save you from future chronic diseases. If you want to test in a reliable laboratory, then we at Agilus Diagnostics have a certified Lab with professional pathologists. For a detailed test, you can visit our site and book an appointment.
