Overview of the LDL7 Subfractions Test
The LDL7 Subfractions test is a specialist lipid blood test assessing seven LDL subfractions within a grouped laboratory assay.
A standard lipid profile generally reports LDL Cholesterol as one overall measurement.
LDL particles, however, are not completely uniform.
Specialist subfraction analysis separates LDL into different fractions to provide more detailed information about the distribution of LDL particles within the sample.
This type of testing may be useful during more detailed cardiovascular or metabolic assessment where conventional Total Cholesterol, LDL Cholesterol, HDL Cholesterol and Triglycerides do not provide all the information required.
LDL subfraction results should not be interpreted in isolation.
Overall cardiovascular risk also depends on factors such as blood pressure, smoking, diabetes, family history, age and other lipid or inflammatory biomarkers.
The LDL7 Subfractions test costs £299.
What Does the LDL7 Subfractions Test Check?
The laboratory assay assesses seven LDL subfractions and reports them through the grouped LDL7 analysis. The assay reports seven LDL subfractions as a grouped specialist analysis.
LDL7 Subfractions
Specialist analysis separating LDL into seven subfractions to provide more detailed information about LDL particle distribution than a single standard LDL Cholesterol result.
Who May Benefit From the LDL7 Subfractions Test?
LDL7 Subfractions may be useful for people seeking more detailed lipid information than a conventional cholesterol profile alone can provide.
People with abnormal LDL Cholesterol - Subfraction analysis can provide additional information about LDL distribution.
People with cardiovascular risk factors - Specialist lipid information may complement conventional assessment.
People with a strong family history of cardiovascular disease - Additional lipid investigation may sometimes be appropriate.
People with metabolic risk factors - LDL particle characteristics can be considered alongside Glucose, Triglycerides and other metabolic markers.
People already undergoing specialist lipid assessment - LDL7 can complement ApoB, Lipoprotein(a) or other advanced cardiovascular biomarkers.
People monitoring lipid-lowering treatment - Specialist testing may sometimes provide additional information when clinically appropriate.
People whose clinician has specifically requested LDL subfraction analysis - The LDL7 assay provides the defined specialist investigation.
How to Prepare
Do not stop statins or other prescribed lipid-lowering medicines simply to obtain an untreated result unless your clinician specifically instructs you to.
The test is most useful when interpreted alongside conventional lipid measurements and the wider cardiovascular risk profile.
Symptoms and Reasons to Consider the LDL7 Subfractions Test
High cholesterol and adverse lipid patterns commonly cause no obvious symptoms, so testing is usually driven by risk factors or previous laboratory findings.
Previously raised LDL Cholesterol - More detailed LDL analysis may be useful in selected cases.
A strong family history of premature cardiovascular disease - Advanced lipid assessment may provide additional risk information.
Previously abnormal Triglycerides or other lipid results - LDL subfractions can complement conventional lipid testing.
Known metabolic syndrome or Insulin resistance - More detailed cardiovascular risk assessment may be appropriate.
Cardiovascular disease despite apparently acceptable standard cholesterol results - Specialist lipid testing may provide additional information.
Monitoring after significant lipid-lowering intervention - Repeat testing can sometimes be used where clinically indicated.
A clinician has requested advanced lipoprotein testing - LDL7 provides specialist information beyond standard LDL Cholesterol.
LDL7 Subfractions cannot diagnose coronary artery disease or show whether an artery is narrowed or blocked.
Cardiovascular symptoms such as acute chest pain, severe breathlessness or collapse require urgent medical assessment rather than routine lipid testing.

Your LDL7 laboratory report is returned securely once analysis is complete.
When Will I Receive My Results?
Results are generally expected within approximately 10 days.
This is a specialist lipid assay and therefore takes longer than a routine cholesterol profile.
Turnaround begins once the sample has been received and entered into laboratory processing.
Understanding Your Results
The laboratory report provides information about the distribution of the seven LDL subfractions assessed by the assay.
These findings should be interpreted alongside standard lipid measurements and other cardiovascular risk information.
An LDL subfraction result does not by itself determine whether cardiovascular disease is present.
Likewise, one favourable specialist lipid result does not remove cardiovascular risk associated with factors such as smoking, diabetes, high blood pressure or family history.
Where results are being used for treatment decisions, clinical interpretation is advisable.
Why Book With London Blood Tests?
London Blood Tests provides private access to specialist LDL subfraction testing for people seeking more detailed cardiovascular information.
Seven LDL subfractions - The assay provides a more detailed breakdown than one overall LDL Cholesterol measurement.
Specialist lipid testing - LDL7 extends beyond a standard lipid profile.
Useful alongside advanced cardiovascular markers - Results can complement ApoB, Lipoprotein(a) and other specialist tests.
Professional blood collection - The specimen is collected and prepared for specialist laboratory analysis.
Approximately 10-day turnaround - Results are generally expected within the stated specialist timeframe.
Clear interpretation boundaries - LDL7 is presented as one component of cardiovascular risk assessment rather than a diagnostic test for heart disease.
Clear pricing - The LDL7 Subfractions test costs £299.
