Warning Letter to Kabe Follows Recent Safety Alert
FDA has issued a Warning Letter to Kabe Labortechnik, the North Rhine-Westphaia, Germany-based manufacturer of the RAM Scientific SAFE-T-FILL Capillary Collection System tubes distributed by ASP Global that are linked to a safety alert issued last month on reports of falsely elevated (false positive) results that have occurred when using the tubes with LeadCare Testing Systems. “These tests may overestimate blood lead levels and give inaccurate results when processing capillary blood samples collected in these ASP Global’s RAM Scientific SAFE-T-FILL tubes,” an agency notice says. Because the root cause is not yet known, FDA is recommending that the tubes not be used with the LeadCare Testing Systems while the issue is being investigated.
The Warning Letter says FDA inspected the firm earlier this year and documented GMP deficiencies. For example, the agency says the firm has not validated the manufacturing process the blood collection tubes. Kabe also failed to adequately ensure that all equipment used in the manufacturing process meets specified requirements and is appropriately designed, constructed, placed, and installed to facilitate maintenance, adjustment, and cleaning, the letter says. Additionally, the inspection found that written Medical Device Reporting procedures do not exist.
The letter noted that because of the serious nature of the violations, all devices manufactured by the firm will be refused entry into the U.S. until the violations are corrected.
