PBMC isolation workflows are protocol-sensitive: timing, tube type, gentle processing expectations, and cold-chain handoffs matter. Speedy Sticks supports research and trial teams with disciplined mobile collection aligned to IRB-approved instructions—especially when participants cannot visit a site easily.

Peripheral blood mononuclear cells, including lymphocytes and monocytes, are the target of CPT and SepMate tube-based collection protocols used in immunology research, clinical trials, and some diagnostic programs. These cells are highly sensitive to collection trauma: a partially clotted specimen, overfilled or underfilled tube, insufficient inversions after collection, temperature excursion above 25 degrees Celsius, or processing delay beyond the validated window can reduce viable cell yield dramatically. Unlike routine chemistry collection where a clean draw is sufficient, PBMC collection demands protocol-exact technique because cell viability, not just analyte concentration, is the measured outcome. Your study's SOP defines every parameter and we follow it without deviation.
CPT tubes contain a density gradient gel that separates mononuclear cells from red blood cells during centrifugation. SepMate tubes use a porous insert design to achieve the same separation. Both require specific fill volumes since under- or overfilling compromises the separation, a precise number of inversions immediately after collection typically 8 to 10, and processing within specific time and temperature windows. These are not parameters to estimate or improvise. The cell yield and viability data from your study depends on these conditions being met exactly. Provide the complete tube handling section of your protocol, not just the tube type, before we confirm the appointment to ensure full compliance with your study SOP.
PBMC collection for clinical trials and IRB-approved research requires adherence to the study's IRB-approved informed consent documentation, protocol-specified collection procedures, and chain-of-custody documentation from draw through laboratory receipt. Sponsor-required deviation reporting applies if any collection step cannot be completed per protocol. Some studies require the phlebotomist to sign protocol compliance attestations or chain-of-custody forms for each visit. Provide all required documentation templates before the visit so we can confirm what will be signed, witnessed, or attested at collection time. For multi-site trial phlebotomy coordination, see our clinical trial blood draw page for broader sponsor and CRO coordination workflows.
PBMC viability degrades rapidly at temperature extremes. Most PBMC protocols specify ambient temperature transport between 18 and 25 degrees Celsius and prohibit refrigeration or heat exposure. Transport should not exceed 4 to 6 hours from draw to processing in most protocols, though some validated windows extend to 24 hours with specific packaging conditions. Dry ice or refrigerants are contraindicated unless your protocol specifically validates those conditions. Thermal packaging, immediate handoff to the courier or processing facility, and avoidance of vehicle trunk storage in extreme weather are all logistics that must be planned before the visit. If your protocol requires immediate on-site centrifugation, confirm equipment availability at the collection site before scheduling.

For teams
Clinics, labs, research teams, and employers use Speedy Sticks to extend collection capacity without sacrificing protocol fidelity. API integration, bulk scheduling, and compliance documentation included.

PBMC blood collection is a specialized venipuncture workflow designed to yield peripheral blood mononuclear cells—lymphocytes and monocytes—for immunological research, clinical trials, and therapeutic programs. Collection requires specific tube types (such as CPT or SepMate tubes), precise fill volumes, gentle inversion, and rapid transport to the processing laboratory to maintain cell viability. Speedy Sticks provides mobile phlebotomy for PBMC collection aligned to IRB-approved study protocols when research participants cannot travel to a collection site.
