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.

自備材料:
采血針、滅菌拭子或棉球、時(shí)鐘、秒表或跑表
注:加樣時(shí),要使用能加樣15μl體積的經(jīng)過校準(zhǔn)的加樣器。
【儲存條件及有效期】
試劑盒在2-37℃貯藏。
試劑有效期為自生產(chǎn)之日起24個(gè)月。
試劑在滿足貯藏條件的情況下可穩(wěn)定使用至效期(效期標(biāo)注在外包裝和試劑盒內(nèi))結(jié)束。
【樣本要求】
EDTA抗凝的新鮮全血。手指血要立即測試,靜脈血可于2-30℃保存3天,但測試前須平衡至室溫(15-30℃),并*混勻。
【檢驗(yàn)方法】
樣本采集和處理:
用標(biāo)準(zhǔn)的靜脈血采集程序采集靜脈血,注入EDTA抗凝管中。全血樣品采集后要盡快測試,如果不能馬上進(jìn)行操作,可將血液在2-30℃保存3天。如果血液被冷藏,測試前將之平衡至室溫(15-30℃),并輕輕混勻。
手指穿刺留取毛細(xì)血管血時(shí),用無菌拭子或紗巾將采血區(qū)擦凈,風(fēng)干,用采血針刺破皮膚,把血液直接收集在EDTA毛細(xì)管中,注滿,立即使用。
檢測前確保所有標(biāo)本都平衡至室溫。
檢測步驟:
檢測前從包裝袋中取出檢測板。打開包裝,把它平放在工作臺面上。
①如果使用毛細(xì)血管血,慢慢將微量毛細(xì)管中的血液加到檢測板右側(cè)的整個(gè)紫色樣品墊上。加樣時(shí)將毛細(xì)管垂直持放,在樣品墊的幾個(gè)部位加樣,一旦樣品墊達(dá)到飽和,就可將毛細(xì)管丟棄處理,本試驗(yàn)未必需要毛細(xì)管中收集的全部血液。到步驟2。
如果使用的是靜脈血標(biāo)本,用加樣頭在血液中吸排幾次,然后慢慢加入15μl血液,打到紫色樣品墊上。到步驟2。
重要提示:加樣不正確可導(dǎo)致結(jié)果無效或結(jié)果無法解釋。
②緊靠紫色樣品墊的下邊有一個(gè)白色墊,垂直加2滴A試劑到白色墊上,第2滴須在*滴被墊吸收后方可加入。不要把A試劑直接加在紫色墊上。
③讓血標(biāo)本流經(jīng)整個(gè)檢測條,但不要使血液溢出或低于檢測條上部的吸收墊,因?yàn)檫@樣會影響檢測條的比較好的沖洗效果。

注意:如果1分鐘后檢測條上的血流阻斷或流動不到條的1/2,可再加一滴A試劑到檢測條下部的白墊上(位于加血的標(biāo)本墊下方)。
④在血標(biāo)本到達(dá)檢測條上部的白色吸收墊底部前,慢慢向檢測板左上方的沖洗墊中加入4滴A試劑,當(dāng)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*吸收。
⑤當(dāng)標(biāo)本到達(dá)檢測條上部白色吸收墊底部的時(shí)候,從檢測板右邊將粘附襯揭去,閉合檢測板。這可使A試劑將血標(biāo)本從檢測條上沖去。為確保檢測板閉合良好,試驗(yàn)流暢,用力按壓結(jié)果窗口的右邊緣。
⑥閉合檢測板15分鐘后從視窗中讀取結(jié)果。不足15分鐘或大于15分鐘讀取的結(jié)果可能不正確。
注:讀結(jié)果時(shí),如有必要可將檢測板傾斜以減經(jīng)結(jié)果窗口中耀眼的光線。
【參考值(參考范圍)】
對惡性瘧原蟲的zui低檢測限是1001-1500個(gè)寄生蟲/微升。
對間日瘧原蟲的zui低檢測限是5001-5500個(gè)寄生蟲/微升。
【檢驗(yàn)結(jié)果的解釋】
有效試驗(yàn)結(jié)果
對照線(C)會出現(xiàn)在所有有效試驗(yàn)中,當(dāng)存在對照線時(shí),試驗(yàn)結(jié)果可如下解釋。注:出現(xiàn)的任意檢測線,即使顏色非常淺淡,也解釋為陽性結(jié)果。
陽性:
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.
陰性:一條紅色反應(yīng)線,即僅在對照區(qū)(C)出現(xiàn)一條紅色反應(yīng)線
【注意事項(xiàng)】
1. 用于體外診斷。
2. 檢測前將檢測卡密封保存。
3. 不要使用超過有效期的試劑盒。
4. 不要將不同批號試劑混合使用。
5. 為了取得比較好的標(biāo)本流量,優(yōu)化試驗(yàn)過程,加標(biāo)本和A試劑時(shí)要照試驗(yàn)步驟操作。向檢測卡上加A試劑時(shí)要注意下列問題:
a. 將A試劑瓶垂直置于檢測卡墊的上方1至2.5厘米處,慢速自由滴入試劑,以使加到?jīng)_洗墊和吸收墊上的試劑量合乎需要。
b. 在將A試劑加到紫色標(biāo)本墊正下方的白色墊上時(shí),需待*滴試劑*被墊吸收后方可加第二滴,必要時(shí)可加入第三滴-見操作步驟3。
6. 如果用的是靜脈血,要輕扣試管或小瓶將標(biāo)本混勻。吸樣前,將標(biāo)本在加樣頭中來回吸排幾次。
7. 如果用的是末梢血,要使用試劑盒中提供的微量毛細(xì)管加樣。
8. 病人標(biāo)本和檢測卡要視為傳染性物質(zhì),按血液傳染源的預(yù)防措施處理,不要再次開封和使用檢測卡。
9. 空氣循環(huán)過度(即:空調(diào)、風(fēng)扇等)可減慢標(biāo)本的流速,建議不要在流速過大的環(huán)境中測試標(biāo)本。
10. 解釋結(jié)果時(shí),使用明亮未過濾的光源。
11. 所有毛細(xì)管和吸頭都是一次性的,不要多份標(biāo)本合用。加樣設(shè)備、容器或試劑的污染可導(dǎo)致結(jié)果不準(zhǔn)確。
12. A試劑用疊氮鈉做防腐劑,疊氮鈉有毒,應(yīng)小心處理,不要誤吸或與皮膚接觸。它可與鉛或銅反應(yīng)形成爆炸性的金屬氮化物。接觸后要用大量清水沖洗。

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.
