2.1.3 Factors Affecting Test Results
• Cariogenic bacteria
– Ascorbic acid may cause falsely high results.
– Results obtained at a temperature lower than 68ºF (20ºC) may not
be accurate.
• Acidity
– Ascorbic acid or calcium chloride may cause falsely high results.
• Buffer capacity
– Falsely high results may be obtained due to ascorbic acid or when
pH is 5.8 or below.
– Falsely low results may be obtained when pH is 7.1 or above.
• Blood
– Ascorbic acid may cause falsely low results.
• Ammonia
– Results obtained at a temperature lower than 68ºF (20ºC) may not
be accurate.
IMPORTANT:
• Only use the SillHa paper (test strip) for use with the instrument.
Do not use any other test strips.
• Carefully read the package insert that comes with the SillHa paper
before use.
• Do not use a test strip beyond the expiration date, or a test strip with a dis-
colored pad even if it is within the expiration date. This may cause inaccurate
results.
• Use the test strip within 10 minutes after removing it from the
foil wrapper. If you remove more than the required number of test strips and
leave them for a while, they may absorb moisture from air, or attract dust
resulting in inaccurate measurement results.
• Do not touch the pad of the test strip with unprotected hands as this may
leave skin oils on it, resulting in inaccurate measurement results.
• Use an oral rinse sample for measurement immediately after collection.
• All the consumables used for each test including the oral rinse solution (puri-
fied water), reagent test strips, and dropper are for single-use only.
Do NOT re-use.
NOTE:
• Do not dispose of the measurement sample until you have successfully
completed the measurement.
