NEW Blood Lead Procedure

FACT SHEET
Contox ZnP Controls

FACT SHEET
CONTOX ZnP Controls

1. The first human blood based Stable Control/Calbrator since 1984.
2. Its application and stability in monitoring the calibration of hematofluorometers was comprehensively field tested/evaluated simultaneously at over 50 Lead Screening Centers in New York City, New Jersey and South Carolina beginning January 1985 until December 1987, totaling over 250,000 determinations using both Aviv & ESA instruments.
3. It is stable for at least 90 days when stored refrigerated between 2-8 degrees Celcius.
4. Contox ZnP Control are shipped cold for minimal exposure to room temperature during transit.
5. Independent studies have proved it to have the most accurate assigned target values when compared with other commercially available products. (Clin. Chem. 1990)
6. It has unique calibration characteristics in having a slightly positive low-end and a insignificantly negative High-end ZnP value bais, when compared to FEP values on actual patient specimens, a preferred feature.
7. Using several lots of Contox – ZnP Controls as part of the Protofluor-Z Hematofluorometer evaluation in June 1987, a cutoff of approxiamately 70 with and 55 without the use of the Protofluor Reagent was recommended.
8. Primarily recommended as a Control to cross validate manufacturers calibration/standard material with a technology different preparation and thus comply with acceptable Quality Assurance Protocol.
9. May be used for ALL models of Hematofluorometers, Aviv, ESA and Helena instruments.
10. Available in Tri-level 1.2 ml/vial or even more economical 2.2 ml/vial formats.
