Culturing for Strep and Rapid Tests(Lab)

In lab this following week we used throat swabs to culture bacteria onto Sheep Blood Agar.  Hopefully this flow chart will help the next time you suspect an infection with any of the Groups of Streptococcus. We also used a simple rapid test called Quick Vue Dipstick to test for Group A Streptococcal antigen.  This test is a lateral flow immunoassay.  A positive test Shows a pink/purple color on the test line and a blue control line which corresponds to a patient being positive for Group A streptococcal antigen.  A negative test is simply the presence of a blue control line only with no color in the test line.

  1. I am from USA. I was suffering from HEPATITIS B for over 3 years, i was hopeless until one of my friend directed me to a herbal DR. Dr Chike on youtube, she said the Dr has herbal medicine that treat HEPATITIS B also said the Dr has helped people with. HERPES, CANCER, DIABETES, HPV, HERPES, HSV 1 .2, Fever, Fibromyalgia, Fatigue and chronic pains. I never believed her but after a lot of talk. I decided to contact him, just few days ago i contacted him and he told me what to do which i did and he sent to me a herbal medicine via {DHL} with prescriptions on how i will take it for a period of days. After i finished taking the medicine for 2 weeks he told me to go for a test which i also did and when the result came out i was surprised to see that i am negative. I am proud to tell you that I am the happiest person on earth. Big thanks to Dr Chike herbs .. I pray you find a solution in him.
