Key Takeaways
- 🧬 HLA DRB1, DQB1 Low Resolution identifies broad HLA genes for transplants and autoimmunity.
- 👥 Best for people planning donor matching, family screening, or autoimmune concerns.
- ⏱️ One simple blood draw or cheek swab.
- 📈 CLIA lab with >99% genotyping accuracy; results don’t change over time.
- 🗺️ Order online, collect sample locally.
What Is The HLA DRB1, DQB1 Low Resolution Gene Test?
This HLA typing test checks your HLA-DRB1 and HLA-DQB1 genes at a low resolution (broad genes rather than very specific gene variants).
It looks for gene groups, like DRB1*04 or DQB1*02, to help with transplant matching and genetic autoimmune risk insight.
One lesser-known detail: other than transplant matching, certain DQB1 groups relate to sleep disorders research, while DRB1 groups can inform immune system matching.
Think of HLA like a “name tag” on your cells, this test reads the big, readable parts to see who best matches you.
- HLA DRB1, DQB1 low resolution results are reported as gene groups.
- Results never change over time because your DNA stays the same.
Why Ordering HLA DRB1, DQB1 Helps
Ordering this HLA typing test can guide matching and rule-in next steps fast.
It supports bone marrow and organ donor matching and can screen family members for potential compatibility.
Some DQB1 allele groups help doctors understand risks tied to certain autoimmune conditions like Lupus, Hashimoto’s thyroid, Multiple Sclerosis, and Type 1 diabetes, which can focus follow-up testing instead of guessing.
Who Should Consider Ordering The HLA DRB1, DQB1 Low Resolution Test
This test is a smart first step for people who want simple, fast HLA information.
- People preparing for potential transplant matching or joining donor registries.
- Families exploring shared HLA patterns for a loved one’s care plan.
- Those who are concerned with autoimmunity.
Labs Included When Ordering Your HLA DRB1, DQB1 Low Resolution
| Test Name | Reference Ranges | What The Biomarker Means |
|---|---|---|
| HLA-DRB1 Typing |
|
Shows your broad HLA-DRB1 “name tag.” It helps with donor–recipient matching and can guide next testing steps. |
| HLA-DQB1 Typing |
|
Shows your broad HLA-DQB1 type. Certain groups relate to immune conditions research and can focus follow-up care. |
HLA DRB1, DQB1 Low Resolution FAQ
Is There HLA DRB1, DQB1 Gene Typing Testing Near Me?
Yes. Use our patient service center locator to find nearby Quest Diagnostics sites for sample collection.
What Is The Cost Of The Test?
The price shown includes all fees such as sample collection at Quest.
Can You Help Me Interpret My Test Results?
Your doctor should review results for care decisions. They may want to run confirmation or follow-up tests for their own records. See our TOS.
How Often Should I Retest?
Usually never. HLA genes don’t change. Retesting is only needed if your clinician requests confirmation for transplant or documentation.
How Accurate Is The Test?
Method: PCR-SSOP (a DNA probe method) used by CLIA-certified labs. External proficiency programs report HLA genotyping accuracy over 99%, reflecting very high analytical sensitivity/specificity for allele calls.
Do I Need To Eat Gluten Or Fast?
No. This is a genetic test, no diet changes or fasting are needed. Show up well-hydrated for an easier draw.
Will This Diagnose A Disease?
No. It shows genetic patterns that can support or rule out next steps. Doctors combine this with symptoms and other labs when needed.
Can This Help With Celiac Screening?
It can help rule out celiac risk if key HLA genes are absent. It may be more effective to test for the HLA DQ2 + DQ8 genes that are more associated with celiac disease. A celiac disease panel may also be helpful.
Is Saliva Accepted?
Quest accepts cheek swabs or blood as acceptable samples.
