Dealing with blood and body fluids every day, testing specimens, providing clinicians with accurate diagnosis and treatment basis, laboratory duties, various professional tips, operating procedures are well memorized - she is Zheng Xinshu, the chief technician rehired by the medical laboratory department of Chongqing 13th People's Hospital, and colleagues affectionately call her "Grandma Zheng".
▲Serious work of "Zheng Grandma"
One afternoon in January 2022, a male patient, Mr. Qin, went to the outpatient department for abdominal pain, and according to the blood routine examination prescribed by the doctor, "Grandma Zheng" found that Mr. Qin's eosinophils accounted for more than 40 percent, and had touched the re-examination rules and had to be re-examined manually. Subsequently, in the blood album found that although the patient's eosinophils are elevated, but the morphology is very normal, by carefully asking Mr. Qin about the working environment and daily diet, combined with years of work experience, Zheng Xinshu highly suspected that Mr. Qin was infected with parasites, and suggested that he take stool for further examination.
▲Hookworm eggs under the microscope
Mr. Qin was very reluctant and was reluctant to do further examinations on the grounds that he was living far away and was too troublesome. After "Grandma Zheng" patiently informed him of the necessity of examination, Mr. Qin finally sent a stool specimen for examination. The initial direct smear examination did not find the parasite. Subsequently, "Grandma Zheng" used the saturated brine floating aggregation method to produce the specimen, and the kung fu paid off, and finally found the hookworm eggs under the microscope.
Hookworm eggs are eggs laid by the parasite hookworm, hookworm is a parasite, a general term for the hook-mouth nematodes, usually parasitic in the human digestive tract, destroying the intestinal mucosa and sucking blood, hookworms will also secrete anticoagulants when sucking blood, aggravating the loss of blood. Hookworms are the most harmful, due to the parasitism of hookworms, which can cause long-term chronic blood loss in the human body, resulting in anemia and symptoms associated with anemia.
"As a laboratory doctor, only by doing your job conscientiously can you be a good clinician's eyes." Zheng Xinshu said this and did the same, engaged in clinical medical laboratory work for more than 40 years, in addition to practicing excellent testing skills, she also cultivated the spirit of craftsmanship of excellence.
The specimen of the laboratory department is only a small tube of blood, a small cup of urine or a small lump of feces, but the test work is not small, each specimen will indicate the patient's current physical condition, and each specimen carries the patient's hope. With her high sense of responsibility and rich experience in morphology, Zheng Xinshu meticulously treats each specimen for examination, which is affirmed by clinicians and praised by patients.
