Na baada ya uchunguzi ikasemekana mashine ndio mbovuNdicho alichokigundua Magufuli "way back" kwamba lazima kutakua na tatizo la Quality assuarance na akatoa maagizo kwamba uchunguzi ufanyike kubaini tatizo lipo wapi.
Tatizo ninyi hamna akili, "Quality" ya maabara inahusu kuangalia "Chain" nzima kuanzia jinsi "sample" inavyochukuliwa, inavyohifadhiwa, inavyosafirishwa hadi inavyopimwa, tatizo linaweza kuwa ni vifaa au watu, au mfumo.
Tanzania tuligundua tatizo lilikua kwenye mashine. Hiyo "Quality assuarance " mnayoifanyia kazi leo, sisi tulikwisha liona hilo miezi miwili nyuma,. Ninyi ndio kwanza mnaliona Leo baada ya kupima watu zaidi ya 90K.
What can Magufuli see while sutting, Uhuru Kenyatta needs to be on top of mount Kenya to see it. Magufuli hoyeeee
Hopeless comment. Are you still locked down you kunyaland?Unaumwa, kutumia akili ni kuitangazia dunia kwamba mmepima mbuzi na mapapai mkitumia mashine mbovu? Au ni kufichua kwamba mlikosa wataalamu na kujiletea aibu kwa kuanika utepetevu na uvivu wenu hadharani? [emoji1] Kuna nini cha kuiga hapo? Tofauti na nyinyi ni kwamba Kenya tuna wataalamu wa kutosha, wazawa, na tunaendesha mambo yetu kitaaluma zaidi. Sio rais mzima na Phd yake ya kimagumashi anaanza kubweka bweka kwamba munahujumiwa na mabeberu, wakati mnajitafuna wenyewe. Majibu tayari unayo kwenye hiyo taarifa uliyoitupia humu, protokali za 'quality assuarance' lazima zitizamwe upya.
"They have assured that they are going to develop a protocol of quality assurance that will help in curbing the conflicting tests."
Endeleeni kupimaHata South Africa wametoa protocol ya ukipimwa mara mbili au zaidi na upatikane negative na kwengine positive, wamesema +ve case ina supersede negative... Hii ni baada ya kuonekana kote duniani kwamba kwavile badoc orona ni ugonjwa mpya, vipimo vyake bado si 100% kwahivyo sometimes kutapatikana false negative (ambayo ni hatari zaidi) au false positive ni jambo ambalo linatarajiwa....
Lakini watanzania, hamfai kuchukulia hii kama sababu ya kuchoma maabara na kutupilia mbali kesi zote za corona....
Hizo test kits za corona zinaambiwa ziko 90% accurate, na kuna test kits zengine hata ziko 70% accurate, hili ni jambo ambalo hata WHO wametangaza... Itachukua mda kiasi kabla hizi protocol za testing ziboreshwe ili test iwe 100% accurate anu angalau 99%... Lakini in the mean time, kupima ndio njia mwafaka manake hata ndani ya 90% accuracy ni bora kuliko kutopima watu kabisa!
TUKISEMA MWENYEZI MUNGU AMETUJALIA WATANZANIA KUPATA RAIS BORA ZAID KULIKO WOTE DUNIANI WATU WANABISHA HAPO SASA WASEME TENA WAKENYA . mMwenyezi Mungu tunakusihi kwa huruma yako umjalie maisha marefu mpendwa Rais wetu Dr. John Pombe Magufuli uliyetupatia wewe mwenyewe atuongoze Tanzania.Imenifanya nicheke sana yani wao ndiyo wanagundua leo [emoji23][emoji28][emoji1787][emoji6]
Mkuu huyo ni mwendawazima achana naye hajui lolote Duniani kote wanamuongolea na kushangaa maajabu ya Rais Magufuli halafu yeye ana post pumba achana naye atakuchefua bure ndugu yanguHopeless comment. Are you still locked down you kunyaland?
Endeleeni kuzikana kisiri siri usiku wa mananeEndeleeni kupima
Kwenye sayansi hakuna kitu kama hiki, ili dawa au kipimo chochote kiweze kukubalika kutumika na WHO lazima kifikie "" required standard", kama ni 98% accuracy, haijalishi ugonjwa ni mpya au ni wazamani, wacha kuzungumza mambo kwa kufuata utashi wako.Hata South Africa wametoa protocol ya ukipimwa mara mbili au zaidi na upatikane negative na kwengine positive, wamesema +ve case ina supersede negative...

Unaongea nini wakati hata hivi vitu vishapimwa na kudhihirishwa hata kumetokea standard formular ya kujulisha nchi husika kwamba ndani ya watu kadhaa unaopima, kuna wengine wana corona na watapatikana -ve , na kuna wengine hawana ila watapatikana -ve kwasababu ya hizi test kits zinazotumika kwa sasa haziko 100% accurate kwahivyo nchi zipime watu zikijua hivyo.Kwenye sayansi hakuna kitu kama hiki, ili dawa au kipimo chochote kiweze kukubalika kutumika na WHO lazima kifikie "" required standard", kama ni 98% accuracy, haijalishi ugonjwa ni mpya au ni wazamani, wacha kuzungumza mambo kwa kufuata utashi wako.
Kama vipimo vitatoa majibu tofauti yenyekupishana kwa mgonjwa mmoja, lazima itafutwe njia ya kuhakikisha muafaka unapatikana, wakati huo huyo mgonjwa akihudumiwa kwa tahadhari kubwa kama vile ni "Positive" ili asipoteze maisha au kuwaambukiza wengine.
Lakini ikitokea Mara nyingi kwamba vipimo vinaonyesha matokeo yenye kutofautiana, hivyo vipimo havitumiki tena kwasababu vitakua vimepoteza sifa yake ya "Reliability", huwezi kuendelea kuvitumia tena.
wewe si mkenya, acha usanii.Kwa taarifa yako sampuli zote za Corona, duniani kote, huwa zinapimwa mara zaidi ya moja, inaitwa 'confirmatory test'. Ndio maana tangu awali nilikuwa nawashangaa na usanii wenu wa maabara yenu moja tu jijini Dar. Maabara yenye mashine mbovu, 'wataalamu' wavivu ambao hawajakidhi vigezo vya kuitwa wataalamu, tena maabara yenye uwezo wa kupima sampuli 300 tu kwa masaa 24! Alafu nchini Kenya maabara mawili tu sasa hivi ndio yanaangaziwa kuhusu hayo matokeo yao. Hivi wiki hii Tz mmepima sampuli ngapi, na zilizopatikana +ve zilikuwa ngapi? Au hata kuhesabu tu sampuli pia ni kibarua kigumu?
Tutaambiwa hata dawa unatakiwa kunywa za makampuni tofautitofauti ili kuhakikisha unapona, da.Kwenye sayansi hakuna kitu kama hiki, ili dawa au kipimo chochote kiweze kukubalika kutumika na WHO lazima kifikie "" required standard", kama ni 98% accuracy, haijalishi ugonjwa ni mpya au ni wazamani, wacha kuzungumza mambo kwa kufuata utashi wako.

Hakuna ugonjwa hapo, ni usanii mtupu. Njoo Tz uone tunavyojiachia, maisha yamerudi nomo kabisa.Unaongea nini wakati hata hivi vitu vishapimwa na kudhihirishwa hata kumetokea standard formular ya kujulisha nchi husika kwamba ndani ya watu kadhaa unaopima, kuna wengine wana corona na watapatikana -ve , na kuna wengine hawana ila watapatikana -ve kwasababu ya hizi test kits zinazotumika kwa sasa haziko 100% accurate kwahivyo nchi zipime watu zikijua hivyo.
Kuna wakati flani hata W.H.O wenyewe waliamua kuongelea kuhusu hili,wakasema zile test kits zao zilidesigniwa ujerumani na zilifanyiwa quality control na kampuni tatu za kuaminika kwahivyo kulingana na wao, corona tests kua inaccurate inawezekana pia ikawa inasababishwa na incompetent medical personel wanaochukua samples vibaya au wanazi contaminate na pia reagents zinazonunuliwa na nchi zinaweza zikawa sub standard kusababisha vipimo kutoka tofauti........ Hayo yote tisa lakini kumi ni kwamba kwasasa bado dunia na madaktari hawajakua experts wa kupima huu ugonjwa, kwahivyo kuna kama 30% ya wanaopimwa wanapata matokeo ambayo siyo..
Utafiti unaonyesha under perfect laboratory quality controll test, hizo test kits zilizokua approved na WHO ni 100% accurate, lakini under real world condition, accuracy inashuka hadi between 66% to 80%! sasa hapo ongezea na uzembe wa madaktari Africa....

Researchers at the Foundation for Innovative New Diagnostics, a nonprofit research center in Geneva, tested five COVID-19 RT-PCR tests and found that all five achieved 100% sensitivity on positive samples, and at least 96% specificity on negative samples in a laboratory setting.
In the real world, testing conditions and process are far from perfect, and accuracy suffers. Researchers still don’t know what the real-world false positive rate is, but clinical sensitivity of RT-PCR tests ranges from 66% to 80%. That means nearly one in three infected people who are tested will receive false negative results.
Collecting good samples is not easy
Most experts believe that problems with sample collection are the main culprit behind inaccurate testing. False negative results are likely occurring because health care providers aren’t collecting samples with enough of the virus for the tests to detect.
This can happen because someone doesn’t insert a swab deep enough in the nose or doesn’t collect enough of the sample. False negatives could occur if a person is tested too early or too late during their infection and there isn’t a lot of virus in their cells. And finally, errors can happen if a sample sits too long before being tested, which allows the viral RNA to break down.
Coronavirus tests are pretty accurate, but far from perfect

Na hii habari ulioleta si mara ya kwanza hili kutokea Kenya,last month madereva 9 wa Kenya walipatikana positive Uganda, waliporgeshwa Kenya na kupimwa na KEMRI wakapatikana wote -Ve, lakini bado wote waliekwa quaranteen manake tunaelewa hilo jambo la accuracy na mbali na hilo tumekubaliana na Uganda kwamba tutaheshimu tests zakutoka kwa mwenzake.
Muda huo wa kuhakikisha kama kila kitu kinaenda sawa na hakuna udanganyifu autolee wapi huy Uhuru? Aache kunywa pombe na kuifisidi nchi ashughulike na afya zenu? Mapesa mlopewa kusaidia Corona hayaonekani yameenda wapi. Chai ya ofisi tu ni 4 million Kenyan Shilling, Bila shaka kuna wataalamu wa Chai na Wizara ya Lishe za maofisini ambao ndio wanaweza kutwambia zilitumikaje.Hilo swali litajibiwa na wataalamu, kuna scenario nyingi sana ambazo zinaweza zikaibua vitu kama hivyo. Hata kwenye vipimo vingine iwe typhoid, HIV au Malaria. Nchini Kenya hiyo ni fani wa wataalamu na watafiti na wizara ya afya. Hutamsikia rais Uhuru Kenyatta akiagiza mapapai yapimwe wala hutamsikia akianza kuimba wimbo wa kuhujumiwa na mabeberu.
ahahahaUnatumia nguvu kubwa kumuelewesha.
Achana naye huyo ila moyoni kashaelewa a nacho bwabwaja sasa hivi ni vile hataki kubali walishafeli kitambo na wanakimbilia kutangaza idadi ya watu wengi ila wapate mikopo na misaada
