lipoprotein - associated phospholipase A2
(LP-PLA2)

Sample type

Serum

Uses

1-Lp-PLA2 is considered a risk marker rather than a risk factor for cardiac heart disease.

2-In conjunction with hsCRP assay can reliably stratify low-, intermediate-, and high-risk populations.

• Increased Lp-PLA2 with low LDL-C increases risk of heart disease two times.

• Increased Lp-PLA2 with high CRP increases risk of heart disease three times.

Precautions

No special precaution required

Interferring factor

1-Smoking increases Lp-PLA2 measurements.

Pre analytical error

Smoking affect the result

Corrective action

Insure that patient does not smoke before the test .

Post-analytical errors

1-Writing a wrong result or wrong name in the report

2-report were sent to incorrect patient

The corrective actions

1- If the report is not delivered to the patient and this error is discovered the correct result or the correct name must be written, but if the report is delivered to the patient must communicate with him and tell him that an error has occurred and replace with the correct report.

2-Communicate with patient ,apologizing for the error, and providing him with the correct report.
