Sample Requirements for Testing in Urine

  1. For sulfatide extraction send at least 10 ml of well-mixed urine (provide any sediment from the sample).  Do not send a very dilute sample. Minimum volume is 5 ml. Urine may be collected and sent overnight Monday through Thursday at room temperature in an insulated container (e.g. styrofoam box). If urine can not be sent immediately, it may be frozen and sent on dry ice.
  2. For sialic acid content screening in urine send at least 2 ml of a random urine sample as detailed above for sulfatide extraction.
