Lipoprotein (a) (Lp(a))

Test Background
Lp(a) is an independent risk factor for cardiovascular disease. Concentrations are genetically determined, with high concentrations being associated with the higher risk phenotype. Quantitation of Lp(a) is performed by an isoform insensitive immunoassay for improved accuracy

Clinical Indications
Measurement of Lp(a) should be considered in patients with a moderate or high risk of cardiovascular disease.

Reference Range

Cardiovascular Risk Stratification:

Low Risk:                     < 60 nmol/L ( < 300 mg/L)

Borderline Risk:            60 - 100 nmol/L (300 – 500 mg/L)

High Risk:                    > 100 nmol/L ( > 500 mg/L)

Sample Required
Serum preferred (red top), heparin (green top) and EDTA (lavender top) acceptable

Sample Volume
0.5 mL


Stable at 2-8oC for 72 hours. Please freeze pending dispatch for analysis.

Sample can be sent by first class post.

Turnaround Time
1 week
