XI. INTERPRETING RESULTS
All test results must be assessed by a qualified medical professional.
Depending on the analyte being assessed, high or low results may have
medical consequences.
If the result reads > (greater than) or < (less than) or results are not as
expected, always repeat the test correctly with a new unused test strip. If a
test result is displayed that is not expected, consult the following table.
MESSAGE or ISSUE
PROBABLE CAUSE
WHAT TO DO
A displayed result
reads < (less than) a
value.*
Result is below the measuring
range of the test.
Repeat the test. Run controls
and confirm that controls are
in range.
A displayed result
reads > (greater than) a
value.**
Result is above the measuring
range of the test.
Repeat the test. Run controls
and confirm that controls are
in range.
Display reads
”_ _
_
_” or N/A.
Result is not available due to
a missing value from a
calculation, or a value is
outside the measuring range.
Repeat the test. Run controls
and confirm that controls are
in range.
TRIGS TOO HIGH LDL
N/A
Lipid panel test triglycerides
result was 400 mg/dL (4.52
mmol/L) or greater.
No action needed. LDL will not
be calculated on samples with
triglycerides of 400 mg/dL
(4.52 mmol/L) or greater.
* For example, the lower measuring ranges for PTS Panels glucose is 20 mg/dL. For lipid panel, the lower limits
are: Chol 100 mg/dL, HDL 15 mg/dL, Trig 50 mg/dL.
** For example, the upper measuring ranges for PTS Panels glucose is 600 mg/dL. For lipid panel, the upper
limits are: Chol 400 mg/dL, HDL 100 mg/dL, Trig 500 mg/dL.
