Fever with bloodshot eyes refers to the symptom of elevated body temperature with bloodshot eyes due to disease. It is common in measles, epidemic hemorrhagic fever, typhus, etc., similar to the rabbit’s eye performance. There are many reasons for fever, both physiological and pathological, and patients should not abuse antibiotics and antipyretics in the mistaken belief that fever is caused by infection. Routine blood test: Blood test is to detect and analyze the quantity and quality of the three systems of formed components of blood, i.e. red blood cells, white blood cells and platelets. Urine: Urine analyzer is also known as dry chemical urine analyzer. The instrument is easy to operate, fast (the fastest 10s can complete the detection of 11 kinds of urine components). Urine routine in the clinic is not to be ignored a preliminary examination, many renal lesions can appear in the early stage of proteinuria or urine sediment in the formation of components. Hematocrit: Anticoagulated blood is placed in a hemocoagulation tube and left to stand vertically; red blood cells sink due to their greater density. The sedimentation rate of red blood cells is usually expressed in terms of the distance they have sunk by the end of the first hour, which is called the erythrocyte sedimentation rate, or hematocrit. Liver function: Liver function refers to the physiological functions of the liver, i.e., detoxification, metabolism, bile secretion, immune defense, etc.; on the other hand, it refers to the medical test items in the hospital’s laboratory, including bilirubin, albumin, globulin, transaminase, r-GTAlkalinePhosphosphosphate, r-GTAlkalinePhosphate, r-GTAlkalinePhosphate, r-GTAlkalinePhosphate, r-GTAlkalinePhosphate, r-GTAlkalinePhosphate, r-GTAlkalinePhosphate and r-GTAlkalinePhosphate. GTAlkalinePhosphatase), serum ammonia (Ammonia), prothrombin time and so on, different items of the examination, representing different clinical significance. Renal function: renal function (renalfunction) refers to the function of the kidneys to excrete metabolic wastes in the body, to maintain the stability of electrolytes such as sodium, potassium, calcium and acid-base balance of the body, renal function tests include blood creatinine, blood urea nitrogen, blood and urine β2 -microglobulin, urinary albumin, urinary immunoglobulin G, urinary secretory immunoglobulin A and so on. Cerebrospinal fluid routine, biochemistry and culture: Cerebrospinal fluid has the role of protecting and nourishing the brain and spinal cord. Normal cerebrospinal fluid has a certain chemical composition and pressure, which plays an important role in maintaining the relative stability of cranial pressure. A lumbar puncture to aspirate cerebrospinal fluid is often performed to assist in the diagnosis of central nervous system disorders. Excessive production of cerebrospinal fluid or obstruction of circulatory pathways can lead to increased intracranial pressure.
