LOAA(Lab on An Array) Real-Time PCR Instrument
6. Precautions in advance during work using LOAA Analyzer
6.1. Laboratory safety and biological risks
6.1.1. General precautions
LOAA Analyzer device do not have biological risks of their own, but according to the standard for non-clinical test control, it
is recommended that all wasted materials be treated as a substance with potential biological risk.
1) Follow all safety instructions printed or attached to the LOAA Analyzer devices.
2) Observe all general safety precautions applicable to electrical devices.
3) Never touch the switch or power cords with wet hands.
4) Do not open the LOAA Analyzer devices or cartridges.
Caution:
Be careful not to pinch your fingers when the device door is automatically closed.
6.1.2. Laboratory precautions
Treat all specimens and wasted materials as if they are infectious. Or refer to other appropriate biological safety procedures.
Comply with the safety guideline of the Occupationally Acquired Infections, Approved Guideline M29 Clinical and Laboratory
Standards Institute (CLSI) Protection of Laboratory Workers or other appropriate safety guidelines.
Wear personal protective equipment and disposable latex gloves while handling reagents or samples, and change gloves
frequently. Wash hands thoroughly after conducting the test.
Caution:
User should be careful in removing cartridge from the device. If the cartridge is broken or leaked, the device and
surrounding areas may be contaminated. Dispose of the cartridge in the waste container for biologically risky
materials.
6.1.3. General PCR precautions
One of the most important guidelines when performing PCR is to prevent contamination. here are some important rules.
1) Sample collection, sample loading to cartridge and LOAA Analyzer operation must be performed in separate
locations or work areas.
2) Do not leave the work area or return to the previous work area without completing the decontamination procedure
at first (cleaning the area and changing protective clothes and latex gloves).
6.2. Decontamination and cleaning procedures
The proposed decontamination and cleaning procedures are intended to limit the spread of contamination due to cartridge
breakage or leakage. Decontamination is necessary to prevent false positives in subsequent tests.
If cartridge leaks or is broken, replace gloves and other personal protective equipment that may be exposed to potential
risk of contamination. Replace disposable gloves frequently, especially during the first stage of decontamination and before
touching a clean surface, during the decontamination process. All disposable protective equipment must be disposed of
properly after decontamination.
Caution:
Contaminated substances of leaked or broken cartridges must be cleaned immediately. A broken cartridge after
PCR may contain a large amount of contaminants. Even if this material is not infectious, it can easily spread
