Condition Description
Galactosemia is a condition that affects how the body processes a simple sugar called galactose. Galactose is present in many foods and is primarily a part of a larger sugar called lactose which is found in all diary products and many baby formulas. The symptoms of galactosemia result from the body's inability to use galactose to produce energy. (NIH, genetics home reference)
Test Methods and Limitations
Fluorometry is a spectroscopy method that measures the fluorescence of an analyte solution. The fluorometer uses a beam of light to excite the electrons of the analyte, and the level of fluorescence created is proportionate to the concentration of analyte, thereby making the concentration of the analyte measurable.
Detailed Sample Requirements
Dried Blood Spots
| Collection Container(s) | Dried blood spot card |
|---|---|
| Collection | Follow kit instructions. Briefly, allow blood to saturate the card until indicated areas are filled and blood has soaked through the card. Air dry the card at ambient temperature for at least 3 hours.
|
| Sample Condition | Follow the instructions provided with the collection set. Store the dried blood at ambient temperature for up to two days. If the specimen cannot be sent as soon as it is dry, the filter paper should be placed in a sealable plastic bag and stored in a refrigerator (≤ 8°C) or preferably in a freezer. |
| Shipping | Follow kit instructions. Double bag and ship overnight at ambient temperature. |
