What This Test Measures

This test evaluates specific genetic sequences (alleles) in a donor’s DNA that are critical for organ or tissue compatibility. It provides detailed, high-resolution data on the genetic markers (e.g., HLA types) to assess how well a donor’s cells may match your own.

Why It’s Used in Transplantation

High-resolution HLA testing is essential for organ transplantation, such as kidneys, liver, or bone marrow, to minimize rejection risks. It helps match donors and recipients based on genetic compatibility, improving outcomes for patients.

Common Uses Beyond Transplantation

Beyond transplants, this test may also be used in stem cell donations, genetic research, or specialized medical procedures requiring precise genetic matching for safety and efficacy.

How the Test Works

The test involves analyzing a blood sample (whole blood, plasma, or serum) to extract and sequence donor-specific genetic markers. Advanced techniques like high-performance liquid chromatography (hplc) or similar methods may be used to detect and compare these markers precisely.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

High-resolution HLA testing reduces the risk of transplant rejection by ensuring a closer genetic match between donor and recipient. It also supports personalized medicine approaches where genetic compatibility directly influences treatment success.
This test is not a routine blood panel but is specifically ordered for patients needing organ transplants, stem cell donations, or specialized genetic evaluations.
What does a high-resolution HLA test involve?
A high-resolution HLA test involves detailed genetic sequencing of specific markers (e.g., HLA types) in a blood sample. It compares these markers between donors and recipients to assess genetic compatibility, often using advanced laboratory techniques like high-performance liquid chromatography or immunoassays.
How long does it take to get results from this test?
Results from a high-resolution HLA test typically take 1–2 weeks, depending on the laboratory and complexity of the analysis. Your healthcare provider will discuss the timeline with you before ordering the test.
