Reflection
What is our “shopping list?”
23
equipment use and care
What can we do to make sure our genotyping equipment is properly cared for?
24
Maintenance
Properly maintained equipment is needed for quality results
Maintenance: Routine and biannual or yearly scheduled maintenance – Reduces breakdowns – Reduces costs in the long run– Minimizes "down time"
25
Introducing New Equipment
Calibrate or verify specified performance upon installation– Pipettes– Centrifuge– Vortex– Etc.
Perform assay equivalence testing– Key components of the genotyping process
(sequencer, PCR machine)– 10-20 samples previously reported and verify
results within expected range of variability
26
Maintenance: Function Checks
Verify that equipment is working properly Performed routinely
– Daily, weekly, monthly– After adjustment or repair
Example:– Monitoring refrigerator temperatures– Verifying pipette accuracy– Checking centrifuge speed
27
Refrigerator and Freezer: Use and Care
Keep organized Periodically clean inside and outside Ensure door is completed sealed when
closing CAUTION! – DO NOT store food items or
beverages in laboratory refrigerator or freezer
28
Refrigerator & Freezer:Temperature Checks
Monitor daily– Refrigerator: 4°C (2°C
to 8°C) – Freezer: -20°C (+/- 5°C)
or -80°C (+/- 10°C) If possible install
electronic monitoring and alarm system
Avoid "frost-free" freezers for storage of critical reagents (enzymes, specimens, etc.)
29
Refrigerator & Freezer:Temperature Log
30
Keep a Log for All Maintenance Activities
31
Exercise: Create a Maintenance Activity List
Purpose:– Use what you have learned in this module and
create a maintenance checklist specific to your test site
Process:– Work in groups of 3-4 (or by test site) – Create a list of maintenance activities on a
daily, weekly, monthly, and yearly basis – You can use the handout as a starting point.– Activity time = 10 minutes
32
Discussion
What equipment and supplies do all labs need for HIVDR testing?
What equipment and supply decisions depend on the testing method?
What challenges do you face in your setting regarding equipment and inventory supply?
