These typing methods, particularly SSP, have permitted rapid HLA typing that does not rely on viable cells, significant numbers of lymphocytes, or adequate antigen expression on different cell types. Thus, testing can be performed using small samples of blood or other tissue that would be inadequate for serologic typing, and provides a highly reliable, reproducible method of HLA typing.

The HLA complex is the human version of the major histocompatibility complex (MHC) which helps the immune system distinguish host cells from invaders. The performance of HLA*LA under reduced coverage (15×) is relatively stable (90%) and comparable to that of xHLA (91%), where xHLA has higher performance on HLA class I (95% compared to 87%), and HLA*LA has higher performance on HLA class II (94% compared to 84%). There is a basic rule in HLA inheritance. The rule is: you have a 25% chance of inheriting all of the same HLA (same 2 haplotypes) as any one of your siblings, you have a 25% chance of not inheriting any of the same HLA (none of the same haplotypes) and you have a 50% chance of sharing I haplotype with your siblings. Allele-level resolution data at primary HLA typing is the ideal for most histocompatibility testing laboratories. Many high-throughput molecular HLA typing approaches are unable to determine the phase of observed DNA sequence polymorphisms, leading to ambiguous results.

A transplant center may decides that additional HLA typing is needed on the CBU, after the HLA-CT results are received.

The crossmatch result should always be interpreted along with known information regarding the recipient's HLA antibodies and the donor's HLA typing. Since the MHC system is involved in recognizing "self" and "non-self" antigens, HLA gene testing may be used to aid in the diagnosis certain diseases, such as autoimmune disease.

For most HLA runs, the Sequencing Center does not review and approve/reject the HLA loci typing results. This function is typically assigned to designated reviewers in the client organization. So in most reports delivered by The Center, the Review status will be “Not reviewed”.

The HLA locus is sequenced with high-quality, paired-end 2 × 150 bp reads, enabling the use of dense polymorphisms to assign phase accurately. This allows unambiguous HLA typing results to be derived directly from the sequencing data

Inform the NMDP of what loci and level of typing are desired. Request Additional Services. As a result of the confirmatory testing, the transplant center may request additional activities. 2021-03-23 Typing HLA-DRB1*04, 07 and DRB4* in the donor’s DRB genes by Pyrosequencing not only yields the same result as using the SSOP typing kit, but also produces the result with a higher resolution. Compared with SSP, SSOP, direct or reverse hybridization, Pyrosequencing can be used to solve ambiguous allele combinations of HLA-DQ and HLA-A/B in a short time.

The percent PRA is the number of wells reactive with the patient's serum expressed in percent. Normal results HLA typing either by serologic (blood fluid) or DNA methods is reported as the phenotype for each HLA loci tested. The antibody screen test is reported as the percentage of panel reactive antibodies (PRA). The percent PRA is the number of wells reactive with the patient's serum expressed in percent. HLA typing has led to some improvement and acceleration in the diagnosis of celiac disease and type 1 diabetes; however, for DQ2 typing to be useful, it requires either high-resolution B1*typing (resolving *02:01 from *02:02), DQA1*typing, or DR serotyping.

Human leukocyte antigen (HLA) typing is used to match patients and donors for bone marrow or cord blood transplants. HLA are proteins -- or markers -- found on most cells in your body. Your immune system uses these markers to recognize which cells belong in your body and which do not.

HLA results will not change over time.

The HLA (human leucocyte antigen) system encodes the major histocompatibility complex (MHC) proteins in humans. These integral cell membrane glycoproteins are responsible for the regulation of the human immune system. There are two classes of MHC, i.e., MHC class I and MHC class II. Human leukocyte antigen (HLA) allele ambiguities are the result of limitations of current HLA typing methodologies.

poor amplification [48]. HLA typing that defines groups of alleles (usually approximating serologic specificities) is referred to as low-resolution or generic typing (For example, HLA- DRBl-04).

However in 36/178 donors As stated before, the patient could haveHLAantibody as a result of transfusions, prior transplants, and/or pregnancies. ThePRA is determined by testing the patient's serum to a panel of 60 different types of HLA. Your tissue typing laboratory staff is always willing and enthusiastic to … An HLA Typing test, like LifeCell’s StemMatch, is a genetic test the purpose of which is to identify an individual’s HLA antigens in the immune system.
