Infections in pregnant women - The role of diagnostic microbiology INFECTIONS pregnant women
Role of diagnostic microbiology
TVRAO Dr. MD
Department of Microbiology
Pregnancy is a dynamic state of health and illness, shared by the pregnant woman and her developing fetus, a concern to the doctor for prompt diagnosis and interventions. Infections with viral, bacterial, parasites and fungi that occur in any pregnant woman as other non-pregnant women of similar age. Most infections are not serious. But some infections are more severe in pregnant women than non-pregnant women because of the risk of vertical transmission to the fetus or infant. There is an awareness on HIV, HBV, CMV, rubella and toxoplasmosis, in rare cases of chickenpox and listeriosis can affect fetal growth. With advances in medical and laboratory technology, we are more concerned about the transmission of HIV, HBV, and we can still interfere with appropriate treatment. It is certain, every pregnant woman needs an effective screening for rubella IgG, the HBV surface antigen and antibodies to HIV outside of the existing protocol for screening of syphilis in all pregnant women VDRL / RPR.
Why a good clinical microbiology services are important
No laboratory test to diagnose a specific disease should be undertaken on an occasional basis test without knowing the consequences of a positive value of the test. Women are more willing to accept routinely offered testing, as in screening for syphilis with. Situations to screen for HIV antibodies turn to be quite different and requires a consent, each woman has the right to refuse any investigation or medical treatment.
Understanding the relationship MICROBIOLOGY their impact on the health of the fetus
There is a gap of understanding between unlimited lab reports and physician, who must always be reduced to improve our quality of services.
1. All requests for any particular molecular or serological testing should be based on clinical symptoms (may not need as HIV, HBV, CMV and syphilis, that are without symptoms at an early stage.)
2. Writing a good clinical history will certainly guide the clinical microbiologist to use the protocol in the right methods.eg laboratory. Toxoplasmosis, CMV, rubella to determine active infection.
INTERPRETATION OF RESULTS rubella, CMV, toxoplasmosis infection by this virus.
1. Clinicians should request IgG in all cases except that IgM is positive in recent infections.
2. The best serologic evidence of recent infections has IgG seroconversion (change from a negative test positive test) to understand all serological tests which prove to be negative on testing first, do not exclude a recent infection. The test must be repeated until three weeks after contact with the suspect, which can be extended up to 6 months in case of diagnosis of HIV infection to the appearance of antibodies.
3. When a specific IgM positive IgG without positive results must be interpreted with caution. If Ig services.
