Frequently Asked Questions

You can download a pdf version here.

1. What does Unique Patient Code on the Laboratory Request Form (LRF) mean?

The Unique Patient Code (UPC) is an identifier for tracking the serum sample test, which ensures the patient’s identity/privacy, and is used for the result communication between physician and Viroclinics. Please clearly indicate the UPC on the serum sample tube. Please use one Laboratory Request Form per serum sample!

2. In case blood collection and pick-up are scheduled on the same day, how long can the serum sample remain at room temperature before the courier pickup?

The serum sample can be left at room temperature for up to 2 hours, after this time it should be stored temporarily in a refrigerator at max 4 ° C before it is picked up by the courier the same day.

3. How long can the serum sample be kept frozen before sending it to the Viroclinics laboratory in the Netherlands?

For quality and testing purposes it is vital that serum samples are stored between -20°C to -80°C degrees. In frozen condition the serum is preserved as needed for an unlimited period of time. 

4. What is the minimum volume of serum needed for testing?

Please isolate 0.5 ml serum per patient (an absolute minimum of 0.25 ml should be provided). 

5. How many serum tubes per patient do I need to send for testing?

Please send only one tube per patient together with one Laboratory Request Form. (1 sample = 1 patient = 1 LRF)

6. Which tube should be used for preparing the blood collection?

7. Which tube should be used for preparing the serum sample?

8. Can the serum sample be stored in a heparin tube?

No, please use a Sarstedt or Eppendorf tube (or similar polypropylene tube). It is not possible to test a serum sample stored in a heparin tube. 

9. Do I need to arrange the shipment box myself?

No, it is the courier’s responsibility to arrange a shipping box and dry ice. You only need to place the serum sample in a biohazard bag (provided by the courier), seal it, and place it in the shipping box. 

10. Does a temperature logger need to be added to the shipping box?

No, a temperature logger is not needed, as the serum sample will be shipped on dry ice. 

11. At what temperature should the AAV9 Antibody Screening kit be stored (used only in Europe, Middle East, and Africa countries)?

Please store the serum sample kit at room temperature.

12. If the courier is asking for a point of contact at the testing lab, how should I respond?

Please reach out to Viroclinics via email for assistance at AAV9-Screening@Viroclinics.com.

13. If I forgot to include the Laboratory Request Form in the shipping box, what should I do?

Please send the Laboratory Request Form by email to: AAV9-Screening@Viroclinics.com. 

13. If I forgot to include the Laboratory Request Form in the shipping box, what should I do?

Viroclinics-DDL is accredited for ISO 15189 by the Dutch Board of Accreditation (RVA). Viroclinics is specialized in the analysis of samples from both clinical trials and patient samples. With a strong track record and a specialty in respiratory viruses, focusing on vaccines, antibodies and antiviral compounds, they recently became highly proficient in the analysis of antibody and cell mediated responses. Viroclinics offer validated assays to detect antibodies against AAVs, vectors and target inserts.
