PCR?is?the?abbreviation?of?polymerase?chain?reaction,?it?is?a?technology?of?amplifying?DNA?sequence?in?vitro,?it?can?be?widely?used?in?the?diagnosis?and?treatment?of?infectious?diseases?such?as?Mycobacterium?tuberculosis?and?hepatitis?virus.?It?is?a?rapid?detection?method?for?infectious?diseases,?and?has?a?high?level?of?sensitivity?and?specificity.?It?has?been?widely?used?in?the?identification?and?drug?resistance?testing?of?tuberculosis?in?China.

The?problems?of?tuberculosis?control?in?China?are:?large?group,?multi?drug?resistant?patients,?and?difficult?management.?Among?them,?the?low?positive?rate?of?diagnosis?is?also?a?prominent?problem.?The?overall?positive?rate?of?tuberculosis?diagnosis?in?China?is?less?than?50%,?far?lower?than?that?in?developed?countries.?In?order?to?promote?tuberculosis?control,?China?has?accelerated?the?popularization?of?molecular?diagnostic?techniques?in?recent?years,?among?which?GeneXpert?technology?and?isothermal?PCR?amplification?technology?are?more?prominent.

China's?tuberculosis?tuberculosis?control?and?prevention?Market?Research?Report?shows?that?China's?PCR?molecular?detection?equipment?is?mainly?distributed?in?three?city?designated?hospitals?in?large?cities,?and?there?are?less?distribution?in?the?county-level?city?and?two?level?hospitals?and?tuberculosis?prevention?institutions.?It?is?expected?that?in?the?future,?with?the?popularization?and?price?decline?of?PCR?equipment,?PCR?molecular?detection?equipment?will?gradually?popularize?and?sink.
