Products and substrates are separated on an ion exchange column and activity is determined by scintillation counting. Liver specimens should be quick frozen immediately after obtaining the specimen. Do not add any liquid to the specimen prior to freezing. Store at -70 degrees C and ship the specimen on dry ice. Turnaround time is 4-7 days.
Prenatal diagnosis is available on cultured chorionic villus cells and amniocytes.
Please contact the laboratory for further details. Turn around time is dependent on cell growth and is usually 1-2 weeks.
