3-5ml venous whole blood is required for the analysis. The blood should be drawn into an EDTA Monovette (purple top EDTA tube) and be spun lightly to avoid partial clotting. Label the Monovette with the patient’s full name, date of birth, and the date of the blood draw.

Please send the Monovette together with the order form and letter of referral by regular mail to our lab:

Paul-Ehrlich-Str. 23

Alternatively isolated DNA samples can also be sent for analysis. The DNA sample should have 5 µg genomic DNA (concentration of at least 50 ng/µl in water or puffer). Label the sample tube with the patient’s full name and date of birth.

Declaration of consent and further documents

Please fill in the order form completely and send it together with your samples to ensure a rapid handling of the case. Especially the signed declarations of consent of the patient (and the family members if necessary) and the signature of the physician on the order form are very important.

Patients with private insurance or orders from foreign countries need an agreement to cover costs or the information that they need a quotation before.

Please note that the handling will be delayed in case of order forms filled out incomplete, a missing signature of the physician, missing data of the patient or a missing letter of referral as well as unsolved assumption of costs.
