Transport of clinical specimens (take blood samples as an example)

In clinical work, the analysis results of test specimens are an important basis for clinicians to diagnose diseases; formulate treatment plans; and the qualification of specimen collection and inspection work directly affects the authenticity of the test results; and then affects the diagnosis and treatment of diseases. In order to further improve the accuracy and reliability of the test results; in addition to requiring the laboratory to improve the quality of the test, it also requires the clinical medical staff to collect specimens correctly. In order to ensure the correct collection, transportation and storage of specimens, Laboratory Science has compiled operating procedures for the collection, transportation, and storage of clinical laboratory specimens, requiring medical staff to strictly follow the operating procedures for collection, transportation and preservation of specimens.

1. Sample collection:

All specimen collection; transportation and processing should be carried out under the principle of aseptic operation; prevention of contamination.

All collected specimens should be placed in leak-proof; transported in sealed sterile containers;

Collect enough specimens.

Each specimen should be marked with the name of the patient; the number to be examined; the source of the specimen; the specific location; the date; the time and relevant clinical information.

Whole blood

When whole blood is used as the specimen to be tested; attention must be paid to the choice of anticoagulant; EDTA-Na2 or sodium citrate is generally used; heparin cannot be used

If the whole blood sample is used for DNA extraction and testing; it can be stored at 4℃ for a short time, if it is used for RNA testing; it should be taken after the blood is taken; RNA should be extracted as soon as possible.

Serum/plasma

DNA determination; can follow the general procedures of serum specimen processing; has little effect on the determination of RNA determination; the way the specimen is obtained and stored has a decisive influence on the determination result. It is best to use EDTA anticoagulation (heparin is strictly prohibited) whole blood specimens; plasma is separated within 6 hours after anticoagulation; if serum specimens are used, serum must be separated as soon as possible (within 2 hours); short-term specimens (1-2 weeks) It can be stored at -20°C, and it should be stored at -70°C for a longer period of time.

2. Delivery of samples

Once the sample is collected, it should be sent to the testing laboratory as soon as possible

If appropriate stabilizer is added to the sample; such as EDTA anticoagulant used for DNA determination, etc.; it can be shipped or mailed at room temperature

Recommendation: Express delivery of whole blood samples or DNA samples in ice packs and foam boxes. Samples that need to extract RNA need to be pre-processed and shipped with 1ml Trizol at low temperature.

Second, the preservation of samples

Routine peripheral blood samples; routine blood samples after collection; within 24 hours at room temperature; can be stored for 1 week at 4°C; for hemoglobin electrophoresis at room temperature for 1 week; electrophoresis can be stored at 4°C for 15 days; DNA extraction samples can be stored at room temperature for 24 hours; 1 sample at 4°C Weeks; -20°C for 3 months; -70°C for half a year to 3 years; RNA extraction samples at room temperature for 6 hours; 4°C for 12 hours; -70°C for 3 months; Amniotic fluid can be stored at 12 hours by centrifugation as above.

China Hematopoietic Stem Cell Donor Database Management Center; unified management and standardized promotion of hematopoietic stem cell volunteer donors; organization; mobilization; HLA (human leukocyte antigen) typing; search for matched hematopoietic stem cell donors for patients with severe leukemia and Provide transplantation related services. Donors’ blood needs to be paired and tested before matching; because volunteers and patients are scattered all over the world; regional inconsistencies coupled with the particularity of blood storage and transportation; this has a greater impact on logistics providers that transport blood. High demands.

　　Our project implementation plan is as follows:

　　①Contact the person in charge of the bone marrow bank branch; confirm the time for volunteers to donate blood

　　②Contact the local agent; express the packaging materials needed in the transportation to the agent in advance

　　③The local agent went to the collection site to collect blood samples

　　④The local agent airlifted blood samples to Shenzhen; SPEED headquarters also couriered relevant documents to Shenzhen

　　⑤After receiving the blood sample, the Shenzhen agent will send it abroad via DHL

　　⑥Foreign customs clearance and delivery

　　⑦Customer signing

Up to now in 2017; Speed Global has successfully delivered more than 140 blood samples; the delivery area covers Europe; the Americas; Australia and Southeast Asia. From the transportation of routine blood samples to the transportation of blood samples with temperature requirements; both have solved the problem of time requirements for blood samples urgently needed to be tested at high speed; the successful delivery of bone marrow bank blood samples has given us a lot of enlightenment; it has made us in the cold chain transportation of the pharmaceutical supply chain We have entered a new level and created new business opportunities.
