Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is Glycogen Storage Disease Type VI?

It is a rare genetic disorder affecting the liver's ability to break down glycogen, leading to liver enlargement and low blood sugar.

• Why is fasting required before the test?

Fasting is necessary to evaluate the body's response and enzyme levels during a state of hunger for accurate diagnostics.

• What is the difference between genetic and biochemical tests?

Genetic testing looks for mutations in the PYGL gene, while biochemical testing measures phosphorylase enzyme activity directly.

• How long does it take for results to appear?

Results typically take between one to three weeks depending on the technique used (genetic or enzymatic).

• Can this test be performed at home?

Yes, home blood sample collection is available, though prior coordination regarding the specific analysis is required.
