By reducing reliance on centralized hub processing, the new model simplifies logistics and eliminates multi-step routing. Previously, shipments often required routing through a central hub, which could add 7-14 days to transit times. Under the updated approach, domestic shipments can now be delivered in as little as 1-2 days, reducing transit times by approximately 70-85% while also lowering overall shipping costs through fewer shipment handoffs. The updated model is supported by enhanced training and operational alignment across iSpecimen's growing global supplier network.
