Vial containing 0.5 ml Bartonella henselae positive IgG human control serum with protein stabilizer and 0.005% thimerosal. Stable at 2-8°C until labeled expiration date.When used undiluted, as provided, specific fluorescent intensity of 3+ or greater should be seen. Optionally, the positive control can be titered to endpoint. If titered, the control should be serially diluted in PBS. When the control has been tested for the endpoint titer by MBL-Bion, an endpoint titer is printed on the positive control vial. Due to variations within each laboratory (fluorescent microscopy, etc.) each laboratory should establish its own mean titer for each lot of positive control (generally + one dilution from stated endpoint).
