Program:Genetics and Genomics
Test Name:Galactokinase (G&G South ACH)
Test Code:GK
Performing Site: Alberta Children's Hospital
Performing Dept:Biochemical Genetics
Availability:Sample sent out on receipt
Preferred Tube/Container:EDTA (lavender)
Alternate:Sodium heparin (dark green - NOT PST)
Lithium heparin (dark green - NOT PST)
ACD A or ACD B (yellow)
Specimen Requirements:1. A separate specimen is required for this testing (i.e., cannot be combined with other
    test requests).
2. Collect 1 x 4.0 mL EDTA tube (or alternate tube type).
Min. Sample Required:4.0 mL whole blood
Specimen Processing:Do NOT centrifuge. Do NOT aliquot. Do NOT freeze.
Keep whole blood sample refrigerated.
Specimen Handling:This sample is stable for up to 10 days if refrigerated.
Keep sample refrigerated at all times following collection and during transport.
Additional Information:Samples will be rejected if:
  • Primary tube not refrigerated
  • Any aliquot is received.
  • Any sample other than whole blood is submitted
    Requisition/Form:Submit request using Biochemical Genetics Laboratory Requisition.
    Please ensure all required information, including patient's clinical history/indication, is provided on the requisition.
    Order Restrictions:This test is considered specialty testing; this test will be cancelled if sufficient clinical justification is not provided.
    Indications:This test is for the investigation of galactokinase deficiency in a patient, either suspected based on clinical presentation (e.g., congenital bilateral cataracts), or found to have excessive galactose in their urine by
    Sugar Chromatography (ACH). Classical galactosemia (i.e., galactose-1-phosphate uridyl transferase deficiency) should be ruled out by a normal Galactosemia Screen, Blood Spot (UAH) and/or Galactose-1-Phosphate Uridyltransferase (ACH) result prior to requesting this test or this test may be cancelled.
    Method Details:N/A
    Reference Interval:Provided on test report by referral lab.
    Comments:Contact ACH Biochemical Genetics Laboratory (403-955-7379) for priority turn-around.
