Overview

HLA B27 PCR test is a blood test that is used to detect the HLA-B27 genetic marker associated with certain inflammatory conditions such as ankylosing spondylitis, reactive arthritis, and uveitis. It is usually recommended for people with persistent back pain, joint inflammation, stiffness, or related symptoms. A blood sample is generally required, and fasting is usually not needed. The HLA B27 PCR test price in Delhi is around INR 1600 to INR 4000, depending on the diagnostic lab and testing method. A positive result indicates that HLA-B27 was detected but does not by itself confirm any disease; results should be interpreted with symptoms and other clinical tests.

What is HLA-B27?

The HLA stands for Human Leukocyte Antigen. These are proteins found on the surface of cells that assist the immune system in determining what is native to the body and what is foreign.

HLA-B27 is one specific type of HLA marker. It is inherited from parents, hence a person's HLA-B27 status is primarily influenced by their genetics.

Some persons who carry HLA-B27 never suffer any associated health problems. At the same time, individuals with specific inflammatory disorders may be more prone to carry this marker.

This is why an HLA-B27 test is typically used in conjunction with symptoms, a physical examination, a medical history, and, in certain cases, additional investigations.

What Is the HLA B27 by PCR Test?

The HLA B27 by PCR test uses a molecular technique known as Polymerase Chain Reaction to detect the presence of HLA-B27-related genetic material.

PCR is a scientific technique for making many copies of a specific region of DNA so that it may be detected more easily. As a result, PCR can be used to identify specific genetic markers within a sample.

A blood sample is often used for the HLA-B27 PCR test. The material is subsequently processed and tested for the HLA-B27 marker using PCR.

The result is often recorded as either positive or negative, depending on the laboratory's testing procedure.

Why is the HLA B27 test done?

Doctors typically offer this test when they suspect a problem that may be linked to HLA-B27.

For example, a doctor might recommend the test if someone has:

• Long-term lower back pain.
• Back stiffness, particularly in the morning.
• Repeated joint pain or edema.
• inflammation of the joints
• Pain at the hip or pelvis
• Repeated cases of eye inflammation
• Symptoms suggest ankylosing spondylitis.
• A family history of certain inflammatory disorders.

The test is not typically used for a general health check. It is more effective when the patient's symptoms suggest an HLA-B27-associated disease.

PCR Test for HLA B27 and Ankylosing Spondylitis

One of the most prevalent disorders associated with HLA-B27 is ankylosing spondylitis, which is an inflammatory condition that mostly affects the spine and pelvic joints.

Ankylosing spondylitis can cause chronic back discomfort and stiffness. The pain can occasionally improve with movement but worsen after extended periods of rest.

HLA-B27 is more prevalent in ankylosing spondylitis patients than in the general population. However, possessing HLA-B27 does not guaranty that a person has ankylosing spondylitis.

In addition to the patient's symptoms and assessment, the doctor may order additional tests, such as X-rays or an MRI.

Other Conditions Associated with HLA-B27

HLA-B27 can also be linked to a variety of other inflammatory disorders.

This may include:

• Reactive arthritis.
• Psoriatic arthritis occurs in some circumstances.
• Certain types of juvenile arthritis
• Certain types of uveitis
• Inflammatory bowel disease-related arthritis
• Ankylosing spondylitis.

It is critical to recognize that HLA-B27 is merely a risk marker. It is not proof that a person has one of these conditions.

What is HLA B27 PCR Test price in Delhi?

The cost of HLA-B27 test by PCR in Delhi NCR usually ranges between Rs 1,600 to Rs 3,200. Also its varies according to the diagnostic laboratory, location, and testing method. Although this is merely an estimate. The actual pricing may vary from one center to another.

If you are looking for an HLA B27 PCR test in Delhi, you should contact the diagnostic center ahead of time to confirm the current price.

Some laboratories may also provide home blood sample collection, which can be beneficial for those who are unable to travel to the center.

HLA B27 PCR Test Preparation

Preparation for this test is usually relatively simple.

Fasting is usually not required prior to donating a blood sample. You can eat and drink normally unless your doctor or laboratory has given you specific advice.

Before the test, inform the healthcare professional whether you are using any medications or supplements. You usually do not need to stop taking your medications just for this test unless your doctor specifically instructs you to do so.

If other blood tests have been ordered at the same time, determine whether they require fasting.

How is the HLA B27 PCR test performed?

The procedure is identical to a routine blood test and normally takes little time.

Then, a small part of your arm is cleansed thoroughly. A sterile needle is placed into a vein, and a little sample of blood is collected in an appropriate tube.

After collecting the sample, remove the needle and cover the area with cotton or a bandage.

The blood sample is subsequently sent to a laboratory. The laboratory use the PCR technique to detect the HLA-B27 genetic marker.

After the testing is completed, the results are compiled and included in the laboratory report.

What Does A Positive HLA B27 Result Mean?

A positive HLA-B27 result indicates that the HLA-B27 marker was present in the sample.

However, this does not necessarily indicate that the individual has an autoimmune or inflammatory condition.

Many HLA-B27-positive people do not acquire a linked condition. When combined with symptoms and other medical findings, the outcome gains significance.

What Does a Negative HLA B27 Results Mean?

A negative result indicates that the test did not find the HLA-B27 marker.

This can reduce the likelihood of certain HLA-B27-associated disorders, but it does not eliminate them entirely.

Even if an HLA-B27 test is negative, a person may still have ankylosing spondylitis or another inflammatory illness.

Benefits of HLA B27 via PCR Test

There are various useful points regarding this test.

• It merely requires a blood sample.
• Usually, fasting is optional.
• The sampling process is rapid.
• PCR is a molecular testing technology that detects specific genetic material.
• It can aid in the evaluation of some inflammatory disorders.
• It can be useful when symptoms point to an HLA-B27-associated illness.
• The test may yield a positive or negative result.

Limitations of the HLA-B27 PCR Test

The most important thing to realize about this test is that it does not diagnose a condition.

A positive result does not guaranty that a person has ankylosing spondylitis or any inflammatory condition. It just indicates that the HLA-B27 marker is present.

Similarly, a negative result does not rule out these possibilities.

The doctor makes the final diagnosis after reviewing the symptoms, physical examination, medical history, imaging investigations, and any additional laboratory testing that may be required.

Who Should Consider Getting the HLA B27 Test?

In general, the test should be performed when a doctor recommends it. It may be beneficial for persons with symptoms of inflammatory joint or spinal illness.

HLA-B27 testing may be recommended for someone who has persistent back stiffness, unexplained joint inflammation, or recurring eye inflammation.

People should not presume that they require this test just because they experience common back discomfort. Back pain can occur for a variety of reasons, and HLA-B27 testing is typically used when the symptoms follow a specific pattern.

Conclusion

The HLA B27 PCR test is a blood test that detects the HLA-B27 genetic marker. This marker is associated with an increased risk of several inflammatory illnesses, particularly those affecting the spine and joints.

The test is straightforward and typically does not require fasting. A little blood sample is obtained from the arm and delivered to the laboratory, where the marker is detected using PCR.

One major distinction is that HLA-B27 is a marker, not a disease. A positive test does not necessarily indicate that a person has ankylosing spondylitis or any other associated disorder. Similarly, a negative result does not rule out an inflammatory condition.
