Qalitex Laboratories provides ISO 17025 accredited probiotic testing services to brands in Los Angeles and throughout the United States. Probiotic products require specialized testing to validate that the claimed strains are present, viable, and at the labeled potency at both manufacture and throughout shelf life. Qalitex Laboratories provides ISO 17025 accredited probiotic testing using culture-based and molecular methods to deliver accurate, defensible results. Our Los Angeles-area clients benefit from proximity to our Southern California labs, enabling faster sample delivery and turnaround times as quick as 48 hours.

Why Choose Qalitex for Probiotic Testing in Los Angeles

Qalitex Laboratories is one of the leading ISO 17025 accredited testing labs in Southern California, with facilities in both Irvine and San Diego. Our proximity to major Los Angeles shipping hubs means faster sample receipt and quicker results. We combine state-of-the-art instrumentation (HPLC, ICP-MS, GC-MS, LC-MS/MS) with experienced scientists to deliver accurate, regulatory-ready results.

Probiotic Enumeration

We perform total viable count (TVC) and species-specific enumeration for commonly used probiotic strains including Lactobacillus, Bifidobacterium, Streptococcus, and Saccharomyces. Results are reported in CFU/g or CFU per serving as required for label compliance.

Strain Identification

We use 16S rRNA sequencing and culture-based identification to confirm strain identity at the species level. Essential for brands making specific strain claims on labels (e.g., Lactobacillus acidophilus NCFM).

Probiotic Stability Testing

Probiotic viability decreases over time. Our stability studies test products at defined intervals to establish accurate expiration dating, ensuring your potency claim is valid at end of shelf life — as required by NPA, USP, and industry standards.
