Lecture 9 - Processing Flashcards
BEFORE SPECIMEN PROCESSING - pre ana
Blood Collection
Positive patient ID
Labelling at the bedside
Getting the specimen to the lab
Barcoded Wristband
barcoded wristband when scanned, provides the patient’s information and ID number
Proper patient ID- Accreditation Canada Standards
Failure to properly identify patients can create adverse events such as blood transfusion errors, diagnostic testing errors, wrong person procedures, etc.
Accreditation Canada Standards : two client identifiers to ensure positive patient identification (PPID) and patient safety.
Two standards
The first is the verbal confirmation that you have the right person using two identifiers
Unique ID number+ full name or
full name + unique ID /DO
The second component is to use the same two identifiers to confirm that the service or procedure was intended for the specific patient –
checking ID against a source like the wristband, requisitions, and labels.
Barcode scanning
eliminates human errors in patient identification, it speed up treatments, lower costs, and guarantee patient safety.
Know what is on a barcode label very important
Specimen Transport Bags
Standard Precautions Specimen transported to the lab in plastic leak proof bags Biohazard signs Never place requisition inside bag with specimen. Place in the outer pouch
Unacceptable
Multiple patients with more than one type of requisition per bag.
Spilled sample
Requisition inside the bag
Specimen Receiving/ and Send out
Once the specimen is collected it is sent to the lab for testing
Specimen arrival time is tracked by the LIS
Technicians receiving the specimen is tracked by the LIS
Technicians doing the phlebotomy is tracked by LIS
After testing specimen storage, retrieval and send out is tracked
Logging and Reporting Process
Pre analytic function
Accurate logging and reporting process must be in place
User ID captured
LIS is interfaced with the analyzers
Functions of LIS
Preanalytic- Post analytic Proper ID of patient Test ordering or order entry Specimen labels Specimen accessioning Specimen receiving/ and tracking
Order Entry-Specimen Barcode or Manual Entry
Patient information Name of doctor, receiving the report Test request time, date Tests to be performed Collection time and collectors initial Name of person entering the test Test priority Any specimen comment NB * a paper requisition or test request form requires the same information as an electronic order The LIS will generate a work list with the collection information
Specimen Accessing- ID number
Number generated by the LIS for each patient specimen
Numbers represented in the bar coding
Process can be generated manually
Aerosol Prevention
To prevent aerosol when a stopper (cap) of a blood collection container is opened, cover top of disposable gauze
Hold tube away from the body
Tube caps are removed behind the shield or biosafety cabinet
Shields acts as a barrier and prevents aerosol entering eyes, nose and mouth.
Biosafety Cabinet
Sash no more than 12”
Keep clear so max air flow
centrifugation
Tubes should be kept capped
Centrifuge cover must be kept in place and left on until the centrifuge stops on its own
Keep on level counter
