Is endocrine function testing a routine blood test

Endocrine function testing is not a routine blood test, and the two belong to different testing items. Endocrine function testing mainly detects hormone levels through samples such as blood and urine, while blood routine mainly checks basic indicators such as red blood cells, white blood cells, and platelets in the blood.

Endocrine function testing usually involves specialized analysis of specific hormones. For example, thyroid function tests will detect indicators such as thyroid stimulating hormone and free thyroxine, while the six sex hormones include estradiol, testosterone, and other items. This type of testing requires fasting blood collection and may require sampling in conjunction with physiological cycles or specific time points. The blood routine is a basic screening item and does not require fasting. It evaluates general health conditions such as infection and anemia through whole blood cell count.

Blood routine includes more than 20 indicators such as hemoglobin and neutrophil ratio, reflecting the hematopoietic function and inflammatory status of the body. The combination of endocrine testing is selected according to clinical needs, such as blood glucose and insulin testing for diabetes screening, and cortisol testing for adrenal diseases. Some endocrine projects, such as growth hormone, also require dynamic testing, which differs significantly from the standardized process of blood routine.

It is recommended to choose the testing items according to the doctor's guidance. Patients with endocrine disorders need to regularly check their hormone levels, and blood routine tests can be performed simultaneously during physical examinations. Avoid vigorous exercise before blood collection, and long-term medication users should inform their doctors in advance to ensure the accuracy of the results.
