Test Code ADHP Familial Hypercholesterolemia/Autosomal Dominant Hypercholesterolemia Genetic Testing Reflex Panel

Reporting Name

FH/ADH Genetic Reflex Panel

Useful For

Aiding in the diagnosis of familial hypercholesterolemia defective apoB-100 in individuals with elevated, untreated low-density lipoprotein cholesterol concentrations


Distinguishing the diagnosis of autosomal dominant hypercholesterolemia from other causes of hyperlipidemia, such as familial combined hyperlipidemia


Genetic evaluation of hypercholesterolemia utilizing a cost-effective, reflex-testing approach

Profile Information

Test ID Reporting Name Available Separately Always Performed
ADHI FH/ADH Genetic Interpretation No Yes
APOBP APOB Genotype No Yes

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
LDLMP LDLR Large Del/Dup Yes, (order LDLM) No
LDLSP LDLR, Full Gene Sequence Yes, (order LDLRS) No

Testing Algorithm

If APOB genotype is negative, LDLSP / Familial Hypercholesterolemia, LDLR Full Gene Sequencing will be performed at an additional charge.


If LDLR full gene sequence is negative, LDLMP / Familial Hypercholesterolemia, LDLR Large Deletion/Duplication, Molecular Analysis will be performed at an additional charge.
