Founded in 1996 on El Camino Real, PrecisionMed in Carlsbad maintains the largest commercially available human cerebrospinal fluid biorepository on the planet. The facility supplies longitudinally collected CSF, matched blood, plasma, and serum samples to pharmaceutical and academic research institutions, processing specimens through the same analytical instrumentation ecosystem anchored by Beckman Coulter nearby on the El Camino Real corridor. Acquired by BioIVT in July 2023, the Carlsbad operation continues to specialize in neurology and oncology biospecimens, including Alzheimer's, Parkinson's, ALS, and cancer liquid biopsy collections with FFPE-matched samples. The predictive biobanking model keeps a robust inventory of annotated specimens ready to ship within one to three business days, a throughput supported by the regional scientific workforce that Marquee Staffing recruits across North County's biotech sector. The repository catalogs more than 35,000 healthy-control and 113,000 diseased-donor CSF samples with full clinical data and matching sera for comparative neurodegenerative disease studies.
