Are these reference materials representative of actual patient specimens?
Reference materials are prepared from human blood, urine or hair, thus the matrix is identical to that of patient specimens. This biological matrix, obtained from unexposed volunteers, is spiked with the appropriate analyte.
Actual concentration (assigned or target value)
Reference material is first used in one of our External Quality Assessment Schemes. The assigned value is usually determinated using the median of the data reported by participants, after removing outliers.
3. Can these biological materials transmit disease?
urine are collected from healthy donors. Each of the donors is screened in
order to exclude, if necessary, any specimens which may be infected by viruses
of the types Hepatitis B (HBV), Hepatitis C (HCV), or Human Immunodeficiency
Virus (HIV), the virus associated with AIDS.
However, each sample should be handled as if capable
of transmitting disease.
What sample volumes are provided for each of those reference materials?
Why is registration compulsory?
For all our blood and serum reference materials, the sample volume provided is approximately 6 mL except for PCB/OC where the volume is approximately 5 mL. For hair reference material, the quantity is approximately 125 mg.
5. What is the shelf life of those
All of our reference
materials are stable for a period of 5 years.
ensures that we have the necessary information to correctly handle you order.
We therefore ask you for a shipping and billing address. Once registered,

is used only for purposes of filling out your order. Since we will invoice
you subsequently, we reserve the right to verify you credit rating prior to
shipment of your order.
8. Minimum order
order a minimum of two samples (either two vials of the same material or two different
materials). You may of course order as many as you like.
9. How long will it take to receive my order?
are already registered, your order will be shipped within 48 hours (excluding
weekends and holidays). You will be sent an email confirmation. If you are
