"What Precautions Should Be Taken When Undergoing Blood Biochemistry Tests?"

Precautions for Blood Biochemistry Examination

If you intend to undergo a blood biochemistry examination, it's not a casual matter. To ensure the accuracy of the test results, there are numerous considerations to bear in mind. You might be aware of some practices, but perhaps not as comprehensively. To this end, we conducted an online interview with Dr. Zhang Guoxiong, an associate chief physician from the University Town Hospital of Guangdong Provincial Hospital of Traditional Chinese Medicine, to elaborate on the crucial aspects of blood biochemistry examination and what steps should be taken prior to the test for enhanced accuracy.

Prior to the blood biochemistry examination, patients are advised to commence fasting after 8 pm the previous evening, abstain from breakfast the following morning, refrain from alcohol consumption, and avoid strenuous physical activities. Should the patient be on medication, they must discontinue taking it during the period of examination. However, Dr. Zhang emphasizes that these preparatory measures are not absolute and should be tailored to individual needs and circumstances.

Impact of Staying Up Late on Blood Biochemistry Examination

Staying up late can indeed exert an influence on blood biochemistry examination results, potentially leading to a mild elevation in liver function indicators. Furthermore, it can also affect the outcomes of electrocardiogram or other tests. From a traditional Chinese medicine perspective, staying up late depletes vitality. For patients with certain conditions such as colds or viral myocarditis, continuing to stay up late might even increase the risk of sudden death.

Effect of Menstruation on Blood Biochemistry Examination

Blood biochemistry examination during menstruation can have an impact on certain indicators. For instance, if a patient experiences heavy menstrual bleeding, the examination may reveal a decrease in red blood cells and hemoglobin levels, leading to a diagnosis of anemia. However, post-menstruation tests typically return to normal, indicating a physiological anemia with minimal impact on overall health.

Even in the absence of illness, it is advisable to undergo regular blood biochemistry examinations at the hospital. This can facilitate early detection and treatment of any potential diseases. Nevertheless, it's important to remember that tests are merely tools. To prevent illnesses, maintaining healthy habits such as avoiding late nights, ensuring adequate sleep, eating regularly with a balanced diet, and engaging in regular exercise to enhance immunity, are equally crucial.
