Where do you keep the specimens that screened negative, how is it stored and for how long?
locked SAMSHA refrigerator in the Specimen Mgt Room, stored by date and SID order, for at least 7 days before being discarded
NN Specimens storage? How? How long?
NNSL are aliquoted for further testing in accessioning and transferred to Specimen Mgmt Room (segregated from negs) for short term storage, stored by SID and date of receipt, until confirmation/SVT is completed. Then stored in Long -term storage (>1yr) (Locked SAMSHA walk in freezer in the Specimen Mgmt Room
Where do you keep Records?
in Secured area -- accessioning, Data Entry, Cert ofc or in Specimen Mgmt Room. Only authorized persnnel have access to records.
What Records are being kept?
CCF, internal chain of custody, screening data, confirmation data, review documents
Where are specimens delivered?
In sort area of CRLs distribution center. Stover delivers in the accessioning dock
What constitutes an administrative error and who stamps it?
missing temp, date and collectors signature. Accessioning stamps and data entry puts it on A hold pending receipt of an MFR.
What constitutes a Problem? How is it dealt with?
Abn odor, A and B bottles different. Accessioner notes problem. aliquotes specimen, assigns a panel ID and placeholder panel and sends the SPECIMEN PROBLEM SHEET witht he CCF to Data Entry.
What is a Fatal Flaw?
Accessioner accessions specimen but does NOT aliquot. Completes a Specimen Rejection Sheet with the CCF to Data Entry and is stored/moved with other specimens in the batch.
How is specimen handling done?
Handle one CCF/specimen at a time, accessioner assigns matching, unique barcode labels to the CCF, specimen bottles, bottle lids and an aliquot tube. Enters SID and CCF# into system and verifies PSI of the bottle, aliquot tube, and the CCF.
What amount is poured by accessioner for screening?
Aliquoting Procedures
Whats the ratio of pos to negs with regards to our blind controls?
20% pos and 80% negs
Where do we get our neg blind controls?
Negs are from commercial source. Screened using FDA approved immunoassay technology. Urine should test negs.
Where do we get our positive blind controls?
From previously confirmed positive samples pooled togther or verified commercial blind specimens.
What is the usual concentration of our pos blind?
>/= 1.5x the screening cutoff concentration.
How do you introduce a blind in your batch?
c-2 accession the blind (do not place barcode on blind test tube) 2. place barcode assigned to Blind Log Sheed 3. write expected result in tul.blnd.scrn.---- 4. record the tube # for the blind. Singn, stamp/printnamde and date 5. send to Data Entryfor demographics. After pouring aliquot, put the blind specimen in the "Recycled Blinds" rack since this will be recycled 4-5 times.
How do we discard the specimes that screened negative.
Neg aliquots from screening are transferred to a rack. Documentation of discard of these aliquots is made on a Discard Log which is filed with the data in the certifiers' office at end of the day.
What is the ratio of a control in a screening batch?
Number of controls must be >/= 10% of specimens plus QC samples in a batch.
How do you accept a batch?
if all QC (and the blind) are acc4eptable for all drugs and SVT analytes
Acceptance criteria for each control: What if a control fails?
If failed drug is "too positive" - only positive specimens in the batch must be repeated with acceptable controls
If a failed drug is "too negative", all negative specimens in the batch must be repeated with acceptable controls.

When do you do IVD and reinjection?
For speciments with very high conc of drug(s) in an attemptto rel=solve ion ratio failure(s) and to improve peak symmetry

In the event of unresolved quantitative failure of a control:
only "true" negative specimens may be reported. All other specimens must be reprepped and reanalyzed.
In the event of unresolved Qualitative failure of a control:
