Check the ingredient i.e. salt concentration and also check whether the blood cell get lysed as some of the microbes need lysed blood cell and some need intact so depends upon needs of bacteria check your case and also see if you have taken a culture which should not be too old.

What type of media is used for growing a culture from a throat specimen?
blood and chocolate agar plates as well as in universities laboratory Nutrient agar plates are also provided
What is alger plates?
Do you mean "agar plates"? Agar agar is a seaweed that, when boiled, makes a product similar to gelatin. This stuff is edible, so vegans who liked jello can have it. It's used by boiling it in water, adding things to it, pouring it into petri dishes and letting it harden to use in making bacteria cultures. Some of the things that are added to it are beef broth--"nutrient agar"--and blood--"blood agar."

How will you check the sterility of the media?
Agar is a medium, so you are checking the sterility of the agar. After preparation one usually places an agar plate at room temperature and another agar plate at 35 to 37 degrees C. After 24-48 hrs of incubation a visual check is made to see if there is any visible growth on the uninoculated plates. If you are adding blood, etc. to the agar, those components can be checked by subbing them to a blood agar plate to see if there is any growth--which would indicate non-sterile components.
How are Petri dishes sterilized?
To determine that an agar plate is sterlize you can keep it overnight in incubator without streaking and if there is any growth peresent in it then it is contaminated and if not then it is obveiously sterlize
Does pseudomonas aeruginosa grow on blood agar?
