Fulgent Genetics accepts various types of specimens. The information below will provide a guide for which type might be best for your situation.
Blood:
  • (2) 4ml in EDTA (lavender top) or ACD (yellow top) tubes, or one of each.
  • for patients less than 1 year of age, we can accept 1-2ml (minimum).
  • This is our preferred specimen type to receive for testing. Blood specimens can be sent at ambient temperature and express delivery should be arranged such that it arrives within 72 hours from collection, otherwise, they will need to be refrigerated.
Extracted DNA:
  • 3μg DNA in EB Buffer. DNA extracted from sources containing Heparin will not be accepted.
  • DNA specimens can be sent at ambient temperature and express delivery should be arranged such that it arrives within 72 to 96 hours from when it was sent.
  • DNA must be extracted from a CLIA-certified laboratory or a laboratory meeting equivalent requirements as determined by CAP and/or CMS.
Saliva / Buccal Swab:
  • DNA Genotek OC-100 kits are preferred and can be provided upon request.
  • (For del/dup analysis, blood samples are preferred as buccal swabs may fail to generate high quality data.)
  • Saliva / buccal swab specimens can be sent at ambient temperature and express delivery should be arranged such that it arrives within 72 to 96 hours from when it was sent.
T-25 Flasks:
  • If you are sending us a prenatal test then we will accept (2) T-25 flasks of cultured cells; ~70% confluency is preferred.
  • Please call to speak with a genetic counselor PRIOR to sending the sample to avoid delays in processing.
  • If you require a Maternal Cell Contamination study then we will also need the mother’s blood in addition to the T-25 flasks.
  • Cultured cell specimens can be sent at ambient temperature and express delivery should be arranged such that it arrives within 72 to 96 hours from when it was sent and refrigeration is recommended for warm weather.
Fresh / Frozen Tissue:
  • 1g of sample from any of the following sources: muscle, liver, spleen, skin, lung, and placenta. (Maternal Cell Contamination study recommended for placenta samples.)
  • Brain tissue and specimens under 1g are not recommended; they are only accepted with special circumstances and approval from a Lab Director.
  • Fresh tissue samples may be accepted if received within 24 to 48 hours after collection and refrigeration is recommended for warm weather.
  • Frozen tissue samples must be stored at -80°C immediately after collection and shipped with dry ice.
  • Tissue samples are very delicate and we will use our best efforts to extract quality DNA. However, the success of extraction cannot be guaranteed.
Patients with Bone Marrow Transplants:
  • DNA extracted from cultured fibroblasts should be submitted instead of blood/saliva/buccal samples from individuals who have undergone allogeneic bone marrow transplant and from patients with hematologic malignancy.
