Decreased activity of the glucose-6-phosphate dehydrogenase enzyme is associated with glucose-6-phosphate dehydrogenase deficiency.
Glucose-6-phosphate dehydrogenase deficiency is a genetic disorder that occurs almost exclusively in males. This condition affects red blood cells which carry oxygen from the lungs to tissues throughout the body. A defect in an enzyme called glucose-6-phosphate dehydrogenase causes red blood cells to break down prematurely (hemolysis) which can cause hemolytic anemia. It is estimated that 400 million people worldwide have glucose-6-phosphate dehydrogenase deficiency. (NIH, genetics home reference)
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.
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. |
