Overview

The purpose of this assay is to detect disease-causing mutations in the HBB gene associated with beta thalassemia. It is used to confirm the diagnosis in affected individuals, identify carriers among high-risk ethnic groups or people with positive family history, and to support prenatal diagnosis of beta thalassemia in families at risk.

Method
PCR, DNA Sequencing
Step 1

Sample Collection

No fasting is required. The consent form is mandatory, especially for prenatal testing. Patients should inform the laboratory about any recent blood transfusion, bone marrow transplant, or ongoing medications.

Method: Peripheral venipuncture

Step 2

Laboratory Analysis

A trained phlebotomist will collect a venous blood sample under aseptic conditions. For home collection, the patient will be guided by the pre-sample instructions.

Step 3

Report Delivery

No specific precautions are needed. The sample will be shipped refrigerated at 2-8°C. Do not freeze the sample under any circumstances. Continue normal daily activities after blood collection.

Timeline: Samples received by Monday 11 am will be reported by Friday. Standard turnaround time is 5 days. Reports are available online, by email, or on WhatsApp.

Patient Instructions

1
Before the Test:No special preparation such as fasting is needed for this test. However, it is essential to complete all required consent forms and provide a clear clinical history and any prior hematological reports. For prenatal testing, genetic counseling before the test is recommended.
2
During the Test:The test involves a simple blood draw. A needle is inserted into a vein, usually in the arm, and a small amount of blood is collected into an EDTA tube. The procedure takes a few minutes and may cause minor discomfort.
3
After the Test:After the blood draw, the puncture site may be bandaged. There are no dietary or activity restrictions. The sample is sent to the laboratory for genetic analysis.

About This Test

Who Should Get This Test

The purpose of this assay is to detect disease-causing mutations in the HBB gene associated with beta thalassemia. It is used to confirm the diagnosis in affected individuals, identify carriers among high-risk ethnic groups or people with positive family history, and to support prenatal diagnosis of beta thalassemia in families at risk.

How to Prepare

  • Sample: 4 mL (2 mL min.) whole blood from a Lavender Top (EDTA) tube.
  • Ship refrigerated. DO NOT FREEZE.
  • Duly filled Prenatal Genetic Testing consent form (Form 18) is mandatory when applicable.
  • Samples must be transported in leak-proof containers to the laboratory.

Doctor's Notes

Understanding Your Results

The interpretation of the beta thalassemia mutation analysis should be performed by a clinical geneticist, hematologist, or trained physician. The result will typically indicate whether a known pathogenic mutation is detected.
Mutation Detected: The report will name the specific mutation(s) identified in the HBB gene. This confirms beta thalassemia and helps define the genotype (e.g., β+ or β0).
Mutation Not Detected: No pathogenic mutation was found among the panel of mutations tested. This does not completely rule out very rare mutations.
Carrier Status: A single mutation detected indicates thalassemia trait, which is usually mild, but can have implications for offspring if both parents are carriers.
Prenatal Testing: The result will indicate whether the fetus is affected, a carrier, or unaffected. This must be accompanied by post-test genetic counseling.
⚠️ When to Consult a Doctor:

Consult a hematologist, clinical geneticist, or your obstetrician if the test result is positive for a mutation, if you are a carrier and planning a family, or if you require guidance on treatment options and genetic counseling.

Limitations

  • ⚠This assay detects more than 100 mutations but does not cover all rare mutations in the HBB gene.
  • ⚠Large deletions other than the 690 bp deletion in IVS-II and Exon 3 may not be detected.
  • ⚠A negative result does not completely exclude carrier status if the causative mutation is not included in the panel.
  • ⚠Results should be interpreted by a qualified clinical geneticist in the context of clinical and hematological findings.

Risks & Considerations

  • ●Bruising or bleeding at the puncture site
  • ●Lightheadedness or fainting during blood draw
  • ●Rare chance of infection at the venipuncture site

Interfering Factors

  • ●Recent allogeneic bone marrow transplantation may result in donor-derived DNA and mask the patient's mutations.
  • ●Whole blood transfusion within 2 weeks can dilute or confound the mutation analysis.
  • ●Contaminated or degraded DNA may compromise PCR amplification.
  • ●Maternal cell contamination in prenatal samples can obscure the fetal result.
