PAL-West Pacific Medical Laboratory in Chula Vista's Third Avenue Village processes clinical specimens from a walk-in phlebotomy station at 629 Third Avenue. Physician-ordered blood panels, including pre-operative metabolic screens and coagulation studies, are drawn and routed through the WestPac Labs network for surgical practices such as Synergy Orthopedics, Chula Vista-Eastlake. The Chula Vista draw site is part of West Pacific Medical Laboratory's multi-location system headquartered in Santa Fe Springs, with central-lab processing capacity spanning hematology, chemistry, urinalysis, and immunology panels. Phlebotomists at this Third Avenue station handle both insurance-covered and self-pay specimen collections, accepting walk-in patients alongside scheduled appointments. The lab's chemistry menu includes hemoglobin A1c and fasting-glucose assays frequently ordered by optometric providers at Eastlake Optometry when co-managing patients at risk for diabetic retinopathy. Automated hematology analyzers at the central processing facility perform five-part differential complete blood counts, reticulocyte analysis, and erythrocyte sedimentation rate testing with same-business-day turnaround on most standard panels.
