According to your description, one of the indicators in the test results is 14.5, while the normal range is between 2 to 10 mU/L. The TSH (thyroid-stimulating hormone) mentioned by the doctor is an important indicator in the screening for hypothyroidism, with a normal range of 2 to 10 mU/L. Additionally, serum phenylalanine (phe) is also significant in the screening for phenylketonuria, with a normal range of 73 to 212 micromoles/L. Please confirm which type of screening the indicator you mentioned belongs to so that we can further understand the meaning of the test results.
