Please be informed weekly about changes in pre-analytical procedures, techniques, reagent shortages, nomenclature, and pricing of our tests, as well as the relocation steps of the various specialties of the laboratory to the new Frépillon site.

Dear Colleague,

Following the start of the new automated conveyor and sorting line, we encountered difficulties that were not evident during the testing phases. Consequently, some tests in the Biochemistry, Autoimmunity, Allergy, and Infectious Serology departments are randomly affected and may experience delays of more than a week. We are working with the different suppliers of the connected analyzers to resolve the identified issues.

Dear colleague,

Be informed every week of pre-analytical changes, technique, reagent disruption, nomenclature and pricing of our exams and the relocation steps of the different specialties of the laboratory to the new site in Frépillon.

DELAYS

Following the start-up of the new tube sorting line and the connected automates systems, we have encountered difficulties that were not apparent during the test phases. As a result, some tests on the Biochemistry, Autoimmunity, Allergology and Infectious Serology benches have been affected and may be delayed by more than a week.
The teams are currently working on both sites (Saint-Ouen l'Aumône and Frépillon) to get the situation back to normal as quickly as possible.

Aspergillus - Confirmation technique (IEP) : new temporary delay of 2 weeks following a break in the screening reagent

Citrates and oxalates
Automaton breakdowns impact our turnaround time of 2 and a half months. In order to return to normal, some files are subcontracted to the Biomnis laboratory when pre-analytical conditions are compatible.

Herpes serology - IgM
Following a break in the reagent supply and the introduction of the alternative technique. We hope to be back to normal next week.

REMOVALS IN PROGRESS

- ZINC : new temporary delay of 10 days

-TRYPTASES : back to normal by the end of this week

-VITAMIN B1 and B6 : new temporary delay of 2 weeks

-FLOW CYTOMETRY FOR THE DIAGNOSIS OF MALIGNANT HEMATOPATHIES : new temporary delay of 7 days
-In case of suspicion of acute hematopathies (acute leukemia, high-grade lymphoma), please notify the arrival of the sample at the address pole.hemato@lab-cerba.com in order to obtain a faster result turnaround.

-VITAMIN A AND E : new temporary delay of 2 weeks.
