Overview of the Apolipoprotein A1 Test
The Apolipoprotein A1 blood test measures Apolipoprotein A1, commonly abbreviated to ApoA1, the principal protein component of high-density lipoprotein particles.
The test assesses 1 cardiovascular marker: Apolipoprotein A1.
High-density lipoprotein, or HDL, participates in the transport of cholesterol away from peripheral tissues towards the liver.
This process is commonly described as reverse cholesterol transport.
ApoA1 is central to HDL particle structure and function.
Measuring ApoA1 therefore provides information related to the HDL-associated side of lipoprotein metabolism.
This is different from simply measuring HDL Cholesterol.
HDL Cholesterol measures the amount of cholesterol carried within HDL particles.
ApoA1 measures the concentration of the principal protein associated with those particles.
The two measurements are related but not identical.
ApoA1 is often interpreted together with Apolipoprotein B.
ApoB reflects the concentration of atherogenic lipoprotein particles, while ApoA1 represents the major HDL-associated apolipoprotein.
The ApoB:ApoA1 relationship can therefore provide additional cardiovascular-risk information.
Lower ApoA1 concentrations can be associated with a less favourable cardiovascular-risk profile.
However, no single apolipoprotein measurement should be used as a standalone prediction of heart attack or stroke.
Blood pressure, smoking, diabetes, kidney disease, family history, LDL Cholesterol, Non-HDL Cholesterol, Lipoprotein (a) and other factors remain important.
ApoA1 is particularly useful as part of a wider advanced lipid assessment.
What Does the Apolipoprotein A1 Test Check?
The test measures Apolipoprotein A1, the principal protein associated with HDL particles. This test measures 1 biomarker.
Apolipoprotein A1
Measures ApoA1, the main structural protein associated with HDL particles, providing additional information about HDL-related lipoprotein metabolism and cardiovascular risk.
Who May Benefit From the Apolipoprotein A1 Test?
ApoA1 testing can be useful for people who want a more detailed assessment of cardiovascular and lipoprotein health.
People undergoing advanced cholesterol assessment - ApoA1 provides information beyond a conventional HDL Cholesterol measurement.
People with a family history of premature cardiovascular disease - Advanced lipid markers can help characterise risk more fully.
People with diabetes or metabolic syndrome - Metabolic disease can alter lipoprotein patterns and cardiovascular risk.
People with low HDL Cholesterol - ApoA1 can provide an additional view of the HDL-associated lipoprotein system.
People with an abnormal Apolipoprotein B result - ApoA1 can be measured alongside ApoB to provide complementary information.
People monitoring cardiovascular lifestyle changes - Repeat advanced lipid testing can help track changes over time.
People taking lipid-modifying treatment - Apolipoprotein measurements can form part of a wider treatment assessment.
People seeking more detailed preventative cardiovascular screening - ApoA1 can complement ApoB, Lipoprotein (a), hsCRP and conventional cholesterol markers.
How to Prepare
Do not stop cardiovascular medication simply to alter the laboratory result.
Where ApoA1 is being monitored over time, similar testing conditions can make serial results easier to compare.
Symptoms and Reasons to Consider the Apolipoprotein A1 Test
Abnormal ApoA1 usually produces no direct symptoms. Testing is used for cardiovascular-risk assessment rather than symptom diagnosis.
Low HDL Cholesterol on previous testing - ApoA1 can provide additional information about the principal HDL-associated protein.
A family history of early cardiovascular disease - More detailed lipid assessment can be useful where inherited risk is suspected.
Diabetes or insulin resistance - Metabolic disease can alter HDL and broader lipoprotein metabolism.
Metabolic syndrome - ApoA1 can complement other cardiovascular and metabolic markers.
A previous low ApoA1 result - Repeat testing can help assess whether the finding persists.
An abnormal ApoB result - Measuring both proteins can provide a broader view of lipoprotein balance.
Ongoing cardiovascular prevention treatment - Advanced markers may sometimes be used to monitor overall risk-factor management.
Normal standard cholesterol despite ongoing concern - Additional apolipoprotein testing can provide information beyond the routine lipid profile.
ApoA1 is a cardiovascular-risk marker rather than a test for acute heart symptoms.
Chest pain, severe breathlessness, sudden weakness or symptoms suggesting a heart attack or stroke require urgent medical assessment.

When Will I Receive My Results?
The current live London Blood Tests page lists a turnaround of approximately 1–2 days after laboratory receipt for Apolipoprotein A1.
The sample undergoes laboratory apolipoprotein analysis, quality-control procedures and result authorisation.
Turnaround begins when the specimen reaches the laboratory rather than necessarily from the exact time the blood sample is collected.
Occasional repeat analysis or specimen issues can extend the expected reporting time.
Understanding Your Results
ApoA1 reflects the concentration of the principal structural protein associated with HDL particles.
A lower ApoA1 result can be associated with a less favourable cardiovascular-risk profile.
However, it should not be interpreted independently of other cardiovascular factors.
A higher ApoA1 result is generally associated with a more favourable HDL-related profile, although cardiovascular risk remains multifactorial.
ApoA1 is often particularly useful when interpreted with ApoB.
A higher ApoB concentration indicates a greater burden of atherogenic particles, while ApoA1 reflects the principal HDL-associated protein.
The resulting balance can provide additional information beyond either marker alone.
ApoA1 and HDL Cholesterol are also different measurements.
HDL Cholesterol measures the cholesterol content within HDL particles, while ApoA1 measures the major protein associated with them.
The laboratory's own reference interval should be used when interpreting the result.
