Genome Sequencing: A Vital Tool Used in Identifying and Tracking New COVID-19 Variants
Genome sequencing is reading or decoding the complete genetic information i.e. “Genome” of an organism that is encrypted in the form of a very long string called DNA made up of 4 letters, A, T, G, and C. The genome of an organism essentially determines their physical characteristics and ...
The Effect of Genetics on Individual Heart Health: Early Identification of FH Variations to Optimize Treatment

Test must be ordered by a Physician.

Familial hypercholesterolemia (FH) is a genetic disorder that is characterized by abnormally high blood levels of low-density lipoprotein (LDL) cholesterol, sometimes referred to as "bad cholesterol". This condition affects an estimated 1 in 250 people, and increases the likelihood of developing cardiovascular disease. In fact, FH is estimated to be the cause of 2-3% of heart attacks in individuals younger than age 60.
