Can I obtain a health certificate if I have high blood sugar?

In general, a health certificate requires fasting, although it is not necessary if the individual only undergoes a physical examination. Typically, obtaining a health certificate involves a series of tests, such as routine blood test, liver and gallbladder ultrasound, fasting blood glucose, and blood pressure measurement. If food is consumed before these tests, it may be digested and absorbed by the body, potentially affecting the biochemical indicators in the blood.

In general, a chest X-ray examination for obtaining a health certificate is primarily used to screen for lung diseases. A chest X-ray is a non-invasive imaging test that uses X-rays to pass through the chest and capture images of the structure and tissues of the lungs. This examination helps in screening and evaluating lung conditions. Common lung diseases include tuberculosis, pneumonia, and emphysema.

In general, you must have an empty stomach when obtaining a health certificate. When applying for a health certificate, certain physical examinations are usually required, such as measuring height, weight, and blood pressure, along with biochemical tests such as blood glucose, cholesterol, and liver function. Therefore, to ensure the accuracy of test results, it is generally recommended not to eat for at least 8 hours prior to obtaining the health certificate.

Transaminases are an important indicator in liver function tests. They mainly exist in liver cells or other organ tissues and participate in substance exchange within cells of various organs. Under normal circumstances, the levels of transaminases in the blood are low. However, when liver cells or other organ tissues are damaged, transaminases are released into the bloodstream, causing elevated levels of transaminases in the blood.

If you are not working in positions involving food processing, catering services, early childhood education, or other roles with direct contact with food for consumption or infants, and if liver function indicators such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are normal, with no symptoms of hepatitis such as jaundice or fatigue, most regions allow you to obtain a health certificate. Although these individuals carry the virus, there is no significant liver damage, and the risk of transmission through daily contact is low.

Hepatitis B surface antibody is a protective antibody. A positive result usually indicates one of two situations: first, the person has previously received the hepatitis B vaccine, prompting the immune system to produce antibodies; second, the person had a past infection with the hepatitis B virus but has since recovered, developing immunological memory. Both situations indicate the absence of current hepatitis B virus infection and demonstrate resistance to the virus, fulfilling the basic requirements for obtaining a health certificate.

The medical examination for a health certificate primarily focuses on infectious diseases such as hepatitis and tuberculosis, aiming to ensure public health and safety. These examinations emphasize diseases that may be transmitted through daily work or life activities, while the transmission routes of AIDS fall outside this scope. Therefore, HIV testing is not included in the routine process of obtaining a health certificate.

Whether hepatitis B virus carriers can obtain a health certificate depends on their specific medical condition. Hepatitis B virus carriers should maintain good lifestyle habits in daily life, such as regular作息 (作息 should be translated as作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息 =作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息作息......
