Venous blood was collected by a standard venous blood collection program and injected into the EDTA anticoagulant tube. The whole blood sample should be tested as soon as possible. If it can not be operated immediay, the blood can be preserved at 2-30 C for 3 days. If the blood is frozen, balance it to room temperature (15-30 C) before testing, and mix it gently.

自备材料:
采血针、灭菌拭子或棉球、时钟、秒表或跑表
注:加样时,要使用能加样15μl体积的经过校准的加样器。
【储存条件及有效期】
试剂盒在2-37℃贮藏。
试剂有效期为自生产之日起24个月。
试剂在满足贮藏条件的情况下可稳定使用至效期(效期标注在外包装和试剂盒内)结束。
【样本要求】
EDTA抗凝的新鲜全血。手指血要立即测试,静脉血可于2-30℃保存3天,但测试前须平衡至室温(15-30℃),并彻底混匀。
【检验方法】
样本采集和处理:
用标准的静脉血采集程序采集静脉血,注入EDTA抗凝管中。全血样品采集后要尽快测试,如果不能马上进行操作,可将血液在2-30℃保存3天。如果血液被冷藏,测试前将之平衡至室温(15-30℃),并轻轻混匀。
手指穿刺留取毛细血管血时,用无菌拭子或纱巾将采血区擦净,风干,用采血针刺破皮肤,把血液直接收集在EDTA毛细管中,注满,立即使用。
检测前确保所有标本都平衡至室温。
检测步骤:
检测前从包装袋中取出检测板。打开包装,把它平放在工作台面上。
①如果使用毛细血管血,慢慢将微量毛细管中的血液加到检测板右侧的整个紫色样品垫上。加样时将毛细管垂直持放,在样品垫的几个部位加样,一旦样品垫达到饱和,就可将毛细管丢弃处理,本试验未必需要毛细管中收集的全部血液。到步骤2。
如果使用的是静脉血标本,用加样头在血液中吸排几次,然后慢慢加入15μl血液,打到紫色样品垫上。到步骤2。
重要提示:加样不正确可导致结果无效或结果无法解释。
②紧靠紫色样品垫的下边有一个白色垫,垂直加2滴A试剂到白色垫上,第2滴须在*滴被垫吸收后方可加入。不要把A试剂直接加在紫色垫上。
③让血标本流经整个检测条,但不要使血液溢出或低于检测条上部的吸收垫,因为这样会影响检测条的比较好的冲洗效果。

注意:如果1分钟后检测条上的血流阻断或流动不到条的1/2,可再加一滴A试剂到检测条下部的白垫上(位于加血的标本垫下方)。
④在血标本到达检测条上部的白色吸收垫底部前,慢慢向检测板左上方的冲洗垫中加入4滴A试剂,当前一滴吸收后,才能加下一滴。注意:第三滴和第四滴可能不能被完全吸收。
⑤当标本到达检测条上部白色吸收垫底部的时候,从检测板右边将粘附衬揭去,闭合检测板。这可使A试剂将血标本从检测条上冲去。为确保检测板闭合良好,试验流畅,用力按压结果窗口的右边缘。
⑥闭合检测板15分钟后从视窗中读取结果。不足15分钟或大于15分钟读取的结果可能不正确。
注:读结果时,如有必要可将检测板倾斜以减经结果窗口中耀眼的光线。
【参考值(参考范围)】
对恶性疟原虫的Z低检测限是1001-1500个寄生虫/微升。
对间日疟原虫的Z低检测限是5001-5500个寄生虫/微升。
【检验结果的解释】
有效试验结果
对照线(C)会出现在所有有效试验中,当存在对照线时,试验结果可如下解释。注:出现的任意检测线,即使颜色非常浅淡,也解释为阳性结果。
阳性:
Two red reaction lines, that is, in the detection area (T1) and the control area (C), each appeared a red reaction line, indicating the infection of Plasmodium falciparum.
Three red reaction lines, that is, in the detection area (T1, T2) and the control area (C), there is a red reaction line. It is suggested that the infection of Plasmodium falciparum, but do not exclude the joint infection of other Plasmodium.
Two red reaction lines, that is, each red reaction line appeared in the detection area (T2) and the control area (C), indicating the infection of malaria parasites in addition to malign abuse.
阴性:一条红色反应线,即仅在对照区(C)出现一条红色反应线
【注意事项】
1. 用于体外诊断。
2. 检测前将检测卡密封保存。
3. 不要使用超过有效期的试剂盒。
4. 不要将不同批号试剂混合使用。
5. 为了取得比较好的标本流量,优化试验过程,加标本和A试剂时要照试验步骤操作。向检测卡上加A试剂时要注意下列问题:
a. 将A试剂瓶垂直置于检测卡垫的上方1至2.5厘米处,慢速自由滴入试剂,以使加到冲洗垫和吸收垫上的试剂量合乎需要。
b. 在将A试剂加到紫色标本垫正下方的白色垫上时,需待*滴试剂完全被垫吸收后方可加第二滴,必要时可加入第三滴-见操作步骤3。
6. 如果用的是静脉血,要轻扣试管或小瓶将标本混匀。吸样前,将标本在加样头中来回吸排几次。
7. 如果用的是末梢血,要使用试剂盒中提供的微量毛细管加样。
8. 病人标本和检测卡要视为传染性物质,按血液传染源的预防措施处理,不要再次开封和使用检测卡。
9. 空气循环过度(即:空调、风扇等)可减慢标本的流速,建议不要在流速过大的环境中测试标本。
10. 解释结果时,使用明亮未过滤的光源。
11. 所有毛细管和吸头都是一次性的,不要多份标本合用。加样设备、容器或试剂的污染可导致结果不准确。
12. A试剂用叠氮钠做防腐剂,叠氮钠有毒,应小心处理,不要误吸或与皮肤接触。它可与铅或铜反应形成爆炸性的金属氮化物。接触后要用大量清水冲洗。

2, samples need low temperature cryopreservation agent? Which one to choose?
For sample preservation, cryogenic cryoprotection may help preserve the sample. Before comparing the composition of microorganisms in stored and fresh samples, a quick way to assess the effect of the protective agent is to test the amount of sample DNA. If the amount of DNA is not sufficient, the method you are using might not be Suitable for the preservation of this microorganism.
RNAlater was originally developed as an RNA preservative by manufacturers such as Qiagen and Thermo Fisher and can now also be used to conserve DNA.
RNAlater is a special sample storage solution, so long as fresh samples are immersed in this liquid reagent immediay after sampling, RNlater can rapidly penetrate into tissues or other biological samples, stabilizing and protecting RNA intact without degradation, ensuring downstream analytical data Real reaction sample expression information.
Curtis Huttenhower, a computational biologist at Harvard University and his colleagues, who participated in the Human Microbiome Project, found that this protective agent can be used if no refrigerator is available after sample collection.
However, some users also reported the RNAlater flaw. Although RNAlater can be used for sample transport, this protectant reduces the number of freshly isolated bacteria from Bacteroidetes and Ruminococcaceae. The other is that if you want to get a sample of high RNA yield, you have to remove it first. Ganz said, "RNAlater will hinder the normal formation of pellet precipitation samples, so RNAlater removed, it must also be washed with phosphate buffer."
In addition, Mak Saito, a marine biochemist at the Woods Hole Institute of Marine Research, points out that there is another problem with RNAlater, which is its high salt content, so in some experiments the cleaning of samples became a problem. Saito used this solution to preserve the protein composition in the marine microbiome.
For some types of samples, micro-organisms can be drastically altered by the addition of low-temperature cryoprotectant, which can not be reconciled, such as soil samples. For fecal samples, cryopreservation sometimes may not be appropriate, for example, samples used to treat C. difficile infections can be stored at room temperature for up to 6 hours without significant changes in the therapeutic efficacy.
Clostridium perfringens type C can produce both alpha and beta toxins and can cause enterotoxemia in newborn calves, foals, piglets and lambs, necrotic enteritis in poultry, acute enterotoxemia in adult sheep and Human necrotic enteritis and so on.
According to C-type Clostridium perfringens infected piglets after the course of the disease can be divided into: the most acute, acute, subacute and chronic four levels.
The most acute type: the symptoms are not easy to observe, occurred in piglets born 24 h, some sick piglets weak, stools were stained with blood loose stools, and soon entered a dying condition, a few do not show any symptoms on the sudden death.
