What Test is Used for HLA Typing?

In the intricate world of immunogenetics, Human Leukocyte Antigen (HLA) typing emerges as a cornerstone, pivotal for a myriad of applications ranging from organ transplantation to the understanding of autoimmune diseases. Capitabio, a leader in the provision of advanced genetic testing solutions, stands at the forefront of this critical field, offering a suite of HLA typing services designed to meet the diverse needs of the medical and research communities. This article delves into the essence of HLA typing, exploring its DNA basis, the methodologies employed, and the various types of HLA tests available.

Is HLA Typing a DNA Test?

At its core, HLA typing is indeed a DNA test. The HLA system comprises a group of genes located on chromosome 6, which encode for proteins essential to the immune system’s ability to distinguish between self and non-self. Given the genetic underpinnings of HLA, DNA-based methods are employed to determine an individual’s HLA type, providing insights that are critical for organ transplantation compatibility, among other applications.

How Do You Test for HLA Typing?

HLA typing involves extracting DNA from a sample of an individual’s blood or tissue. Once the DNA is isolated, it is subjected to various techniques designed to identify the specific alleles present in the HLA genes of interest. The choice of technique depends on the required resolution of typing and the specific application for which HLA typing is being conducted.

What Are the Different Types of HLA Tests?

HLA tests can be broadly categorized based on the level of resolution they provide and the specific HLA loci they target. Some of the key types include:

  1. Low-Resolution HLA Typing: Often used for preliminary screening, low-resolution typing identifies the major groups of HLA alleles, providing a broad overview of an individual’s HLA type.

  2. High-Resolution HLA Typing: This type of test offers a more detailed analysis, identifying specific alleles within the HLA genes. High-resolution typing is crucial for applications such as bone marrow transplantation, where precise matching between donor and recipient is essential.

  3. HLA Antibody Screening: Beyond allele typing, HLA antibody screening tests are used to detect antibodies against HLA antigens. This is particularly important in transplant medicine to assess the risk of organ rejection.

What Methods Are Used for HLA Typing?

Capitabio employs a range of state-of-the-art methods for HLA typing, each selected for its ability to meet the specific needs of our clients. These include:

  1. Sequence-Specific Primer (SSP) PCR: A rapid and cost-effective method, SSP PCR is used for both low and high-resolution typing, utilizing primers specific to known HLA alleles.

  2. Sequence-Specific Oligonucleotide (SSO) Probing: This technique involves hybridizing PCR-amplified DNA with labeled probes that bind to specific HLA sequences, suitable for intermediate to high-resolution typing.

  3. Sequence-Based Typing (SBT): Representing the gold standard for high-resolution HLA typing, SBT directly sequences the DNA of the HLA genes, providing detailed allele information.

  4. Next-Generation Sequencing (NGS): The most advanced method available, NGS offers unparalleled resolution and depth, allowing for the comprehensive analysis of the HLA region. Capitabio’s  next generation sequencing platforms services cater to the most demanding HLA typing applications, ensuring precise matching and compatibility assessments.
