What should be done if a newborn has low C14?

Patient's question:

Hello, my newborn's physical examination results are C14/C30.03. The minimum value here is 0.04. Another C16/C3 is 0.32, and the minimum value here is 0.43. Another C18/C3 is 0.15, and the minimum value here is 0.17. What should I do?

Doctor's answer:

According to your description above, it is suggested that if this number is relatively low for the child's only blood collection, it cannot be ruled out that there may be a genetic metabolic system disease. Therefore, in this case, it is best to perform tandem mass spectrometry enzyme testing to check for any carbohydrate metabolism abnormalities or amino acid metabolism abnormalities. If this is the case, this can only be symptomatic treatment, and there is no other definitive treatment. Nutritional support should be strengthened. I recommend that you communicate in detail with your doctor to see.
