To guarantee that the laboratory results are not influenced by external environmental factors, the following pre-analytical procedures should be followed:

Please only use our specially provided laboratory kits for testing. Unless otherwise requested, each kit contains the following:


2 x Serum tube (brown top)

1 x Heparin tube (blue top)

1 x EDTA tube (red top)

3 x CPDA tubes (yellow top)


Please collect the blood from Monday to Wednesday (not on Friday or before a public or Bank holiday). All material should be delivered to the BCA-lab for analysis from Monday to Friday or on Saturday morning.

After they have been filled with specimen, the cell-stabilising CPDA tubes allow a maximum shelf life of up to three days, so please post them as soon as possible.

On the Declaration of Consent laboratory order form (Cost Assumption Declaration), please tick the necessary examinations and ensure that the patient also signs it (if you are not the patient).

NB: The blood must be stored at room temperature and not be stored in a cool place, especially not in the fridge.

Furthermore, the blood should not be centrifuged, with the exception of blood being prepared for antibody tests such as ELISA or Immunoblot.

Note: Please use the enclosed packaging for transport, which is up-to-date with current mail regulations.

If you have any further enquiries, need assistance or want to request further test packages, please do not hesitate to contact us.

BCA-lab is open every day from Monday to Friday. Office hours are 8:00 a.m. to 5:00 p.m.
