Coordinator Responsibilities

Competency Reassessment• 6 month reassessment• Annual reassessment• Monthly QC• Internal PT (at monthly visits)• Direct observation (at monthly visits)• Written test

What is Quality Control?– Does a new reagent lot perform properly? Lot Validation – performed centrally– Chemical reagents deteriorate.

How do you assure yourself that procedures are working properly?

Check with known QC specimens regularly (weekly)– Do operators perform testing properly? Run QC at least once a month– Are transport and storage conditions satisfactory? Run QC every shipment, and if storage temperature is out of range– What happens if there is a problem? Records permit follow-up by lot and by patient

Responsibilities of the Counselors

Quality control• QC weekly (every Monday)• QC each shipment• QC by each person monthly (ie Rotate this

responsibility)• Control line and background color each test• If anonymous testing is being done

Coordinator Responsibilities

Quality Control– Check QC log weekly– Each operator must run QC at least once a month

What is Proficiency Testing?

• External audit of performance– External unknowns are received from CAP 3 times per year– Results graded to national norms– Reviewed by state for licensure

• Analyzed by testing personnel as they would a patient specimen• Unacceptable results require investigation and a written response• RWJMS Internal Proficiency Testing

– Part of monthly oversight visits– Part of operator recertification process

Responsibilities of the Counselors

• Specimens will be sent to you directly from the CAP during the weeks of:– Feb. 9, 2004 – THESE WILL BE YOUR PRE-LICENSURE RESULTS!!– May 3, 2004– Sept 20, 2004

• These specimens should be tested promptly• Sign the Attestation Statement• Fax results back to our office within 5 days (fax set to FINE or EXTRA FINE!!)• Dr. Cadoff will sign off on these centrally and we will relay them to CAP• Successfully participation in a PT event is part of the operator recertification

process and state licensure!

Coordinator Responsibilities

Proficiency Testing• Unacceptable results require investigation and a written response• RWJMS Internal Proficiency Testing

– Part of monthly oversight visits– Part of operator recertification process

Why Inventory Control?

• Standardization of reagents and supplies

• Validation of reagents

• Replacement of supplies and consumable

• Bulk purchasing (save $$)

Responsibilities of the Counselors

• Don’t buy your own stuff. Ask us for it.

• Use the order form and/or call Fran

• Fran will call you before your next scheduled visit

• Anticipate your needs

Coordinator Responsibilities

Inventory Control:

• Don’t buy your own stuff. Ask us for it.

• Use the order form and/or call Fran

• Fran will call you before your next scheduled visit

• Anticipate your needs

Why Temperature Control?

• Reagents deteriorate

• Manufacturer validated storage conditions (35-80oF)

• Corrective action if temperatures are out of range

Temperature Monitoring

Responsibilities of the Counselors

• Record storage temperatures daily– Refrigerator (controls) and Storage room

(OraQuicks)– Testing areas– Reset Min/Max thermometers

• If storage temperature out of range, perform QC

• If testing area out of range, TEST ELSEWHERE

Coordinator Responsibilities

Temperature Control:

• Review temperature logs weekly

• Send logs to Fran monthly

Why Testing Logs?

• Control inventory (Are we almost out? Are tests missing?)

• Reagent recall (Need lot numbers! Can we call clients back?)

• QC monitoring (Was it done yet today? Did I run my required QC this month?)

• PT monitoring (Competency assessment tool)• Problem logs (What happened?)• Logs will be reviewed centrally each month

Responsibilities of the counselors

• Check Expiration dates• Record QC, PT, client testing in the log• Record reagent and QC lot numbers• Check the temperature and testing logs before running

a test, to see if QC is needed• Document any problems on the back of the log, with a

note on the front• Site coordinators need to review them weekly, and send

them to Fran each month.• Sign legibly! (Name once per sheet, then initials, is OK)

Coordinator Responsibilities

Testing logs:• Review testing logs weekly• Review QC rotation before month-end• Send logs to Fran monthly

Why monitor Preliminary Positives?

• Check OraQuick’s performance

• Check appropriateness of confirmatory testing system (phlebotomy vs fingerstick)

• This is new to all of us

Responsibilities of the counselors

• Collect specimen for confirmation– Phlebotomy preferred– Fingerstick acceptable

• Fill out Prelim Positive form for all positives

• Fax the form to Fran• When confirmatory result is back, add it

to the form and send/fax it to Fran

Coordinator Responsibilities

Preliminary Positives:

• Make sure Prelim Positive forms are completed and faxed to Fran

• Phlebotomy services should be made available (counsellors? contract?)

LABORATORY TRAINING

General Concepts

Orasure Oraquick HIV

Details of Testing

Orasure OraQuick Qualitative HIV • Check Test and Temperature log to see if QC is needed• CHECK EXPIRATION DATES!!• Once opened, Orasure External QC reagents are only good for 21 days if

stored in the refrigerator! • Put on gloves.• Open both portions of the test pouch. Make sure that an absorbent packet

was packed with the test device. If not, discard the device and open a new pouch.

• Label both the Developer Solution Vial and the test Device with the subject’s name or ID.

– Be careful not to block or cover the two holes on the back of the test device.– You might want to position the tube so you can see through it without the paper

label in the way.• Remove the cap from the vial, making sure that you are wearing disposable

gloves.

ORAQUICK HIV

• POINTS TO REMEMBER– Label both the test device

AND the developer solution with an identifier

– Timing begins when you add the test device to the developer solution!

– Several specimens can be set up together by placing specimen loops into the labeled developer vials – Mix thoroughly, THEN

– Add labeled testing devices and begin timing.

Oraquick Qualitative HIV Antibody

• Clean the finger of the person being testing with an antiseptic wipe, and allow it to dry.

• Spring-load the lancet, and puncture the finger a little off-center of the fingertip.

• Take a clean, unused Specimen Collection Loop, and fill the loop completely with blood.

• Give the person gauze and have them squeeze to stop bleeding.

Oraquick Qualitative HIV Antibody

• Insert the blood-filled end of the loop into the solution in the vial and stir. If blood did not fully fill the loop, or if the solution is not pink, discard the test materials and start again.

• Insert the flat pad of the test device (labeled with the test subject’s ID) into the vial with the blood in the developer solution. Make sure that the pad touches the bottom of the vial, and that you can see the result window.

Oraquick Qualitative HIV Antibody

• Start timing the test. Record the start time on the test log sheet.

• Read the results after at least 20 minutes, but not more than 40 minutes have passed. If the test is not read within 40 minutes, discard the test materials and start again. The test is INVALID..

INTERPRETATIONS:– PRELIMINARY Positive – Lines at T and C– NEGATIVE – Line at C– INVALID – No line at C, too much pink background, extra lines, or

anything else odd – Do not report the result.– No other interpretations!

• Complete the testing log (whether or not the test was successful).• If Quality Control is not correct, consult procedure manual. Do not test

patients.

Test Validity

• A red control line must appear within the C triangle. – If it is absent, the test

is INVALID– If the line appears

outside the C triangle, the test is also INVALID

INVALID RESULTS

• Red background interferes with interpretation• No control line is visible• Control line is outside C triangle• What’s that at the top of the cassette?

A PRELIMINATRY POSITIVE RESULT

• Read between 20 and 40 minutes

• A line is present within the C triangle

• Another line is present within the T triangle

• NO MATTER HOW FAINT

• Intensity of the T line IS NOT related to antibody concentration!!

A Negative result

• A red control line appears within the C triangle.

• No other line, no matter how faint appears in the T triangle
