2. What are all the types of samples accepted?

Whole blood, dried blood spots on filter paper, buccal swabs, DNA.


3. What are all the Loci that can be typed?

HLA–A, HLA–B, HLA-C, HLA-DRB1, HLA-DQB1, HLA-DQA1, HLA-DPA1, HLA-DPB1, and KIR.


4. What are all the supported resolutions?

We provide two levels of resolution with HLA-SBT:

- Gold level: all ambiguities will be resolved in the antigen recognition sites (ARS); that is exon 2 and 3 for Class I and exon 2 for class II.

- Silver level: a majority of ambiguities will be resolved.


5. What are the normal turnaround times?

- 3 days for ultra urgent samples
- 5 days for clinical samples
- 14 days for Class I for non-clinical samples
- 21 days for Class II for non-clinical samples
- 28 days for research samples

We can report faster upon special request. Contact us


6. What are all the supported client profiles?

Donor registries, transplant centers, donor centers, cord blood banks, hospitals, pharmaceutical companies, and clinical research projects.


7. How should we ship the samples?

FedEx is a our preferred carrier to ship samples. Here’s our address


8. What Exon do you normally type?

We routinely perform SBT for exons 2 and 3 for HLA-A, -B and –C. On request, we perform typing for exons 4 and 7 to rule out some null alleles in HLA-A, -B and –C.

Most published alleles do not have exon 4 sequences available in the WHO HLA database; therefore typing for exon 4 can be difficult. One other problem is that with current available technologies to separate the phase of alleles is not always possible in other exons.

We recommend following ASHI and NMDP guidelines for typing those exons.
