Why edta blood not suitable for culture?
EDTA kills bacteria or renders it un-viable for growth. EDTA chelates metals that some bacteria need for growth.
What does a culture medium provide to a living thing?
Culture media in microbiology is a media where microorganisms like bacteria from a sample is grown into colony for the identification of particular organism.eg-simple media like blood agar,choclate agar
Definition of culture and sensitivity tests?
A collection of a urine sample, blood sample or other body fluid samples are cultured in medium and analysed with for sensitivity. A "C&S" is a diagnostic lab procedure used to identify the type of bacteria and to determine which antibiotics can successfully fight an infection. C&S is primarily used to find bacteria. The absence of bacteria does not mean there is no infection, since it could be a virus that will not grow in a specific culture medium.
What does a preliminary urine culture result mean?
Preliminary urine culture might just be a Urinalysis (UA), in which they check for white blood cells in sample. White blood cells are a sign of inflammation. No matter what the preliminary culture says, you should wait for the results of the Urine Culture (24-48 hours) as it can provide more information about the possible infection.
Blood culture?
DefinitionA blood culture is a laboratory test to check for bacteria or other microorganisms in a blood sample. Most cultures check for bacteria.A culture may be done using a sample of blood, tissue, stool, urine, or other fluid from the body. See also:Bronchoscopic cultureCSF cultureEndocervix cultureFecal cultureThroat swab cultureUrethral discharge cultureUrine cultureAlternative NamesCulture - bloodHow the test is performedA blood sample is needed. Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.It is very important that the blood sample does not become contaminated. The sample is sent to a laboratory, where it is placed in a special dish and watched to see if microorganisms grow. This is called a culture. Most cultures check for bacteria. If bacteria does grow, further tests will be done to identify the specific type.A gram stain may also be done. A gram stain is a method of identifying microorganisms (bacteria) using a special series of stains (colors). For example, see skin lesion gram stain.How to prepare for the testNo special preparation is needed for a blood culture. For information on preparing for a blood sample, see venipuncture.How the test will feelThere is no pain associated with a blood culture. For information on how giving a blood sample feels, see venipuncture.Why the test is performedYour doctor may order this test if you have symptoms of a blood infection such as bacteremia or septicemia, a serious, life-threatening infection that gets worse very quickly.The blood culture will help identify the type of bacteria causing the infection. This helps the doctor determine your best course of treatment.Normal ValuesA normal value means that no bacteria or other microorganisms grew in the laboratory dish.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAn abnormal (positive) result usually means that you have bacteria or other microorganisms in your blood. This is a sign of infection.However, contamination of the blood sample can lead to a false-positive result, which means you do not have a true infection. Your health care provider can help determine the difference.What the risks areThe blood culture is done in a lab. There are no risks to the patient. For information on risks related to giving a blood sample, see venipuncture.Special considerationsA bacterial blood infection sometimes comes and goes, so a series of three blood cultures may be done to confirm results.ReferencesShapiro NI, Zimmer GD, Barkin AZ.

How is acute lymphangitis diagnosed?
A sample of blood would be taken for culture to determine whether the bacteria have entered the bloodstream. A biopsy (removal of a piece of infected tissue) sample may be taken for culture to identify which type of bacteria is causing the infection.
What is blood culture?
A blood culture is a lab test done to see if there are any bacteria in the blood.
What is culture negative bacterial endocarditis?
Endocarditis is an inflammation of the endocardium (part of the heart), and if it is bacterial, the cause for it is bacteria. The part of the term culture negative, means that they tried to grow the bacteria in the lab after taking a blood sample, and were unable to get it to grow.
How do you collect the sample for blood culture?
go to a docter
Blood cultures are performed to diagnose what?
which bacteria are responsible for infections.
Reason for culture coming back negative on cellulitis?
Cultures look for bacterial growth. And thus in order for bacteria to grow in a given culture medium LIVE bacteria are needed. Depending on the mechanism for obtaining a sample, and the sample placed in the culture medium (i.e. swab, probe, biopsy, blood, etc.) the probability of obtaining live bacteria varies. Pus that usually accompanies an infection is composed of dead bacteria within white blood cells. And thus the swab of a skin wound full of pus is UNlikely to yield a positive (defined by bacterial growth in the culture medium) result. In short live bacteria is needed for a culture to be reported as positive. Not all samples taken for culture contain live bacteria, even in the presence of an infection (it is just the live bacteria are too deep to be accessed by the sampling technique used. I hope this answers your question. Sincerely, Matthew C. Lee, MD, RPh, MS
What to do when puppies poop blood?
I would suggest taking your puppy to your veterinarian, along with a sample of the bloody feces. In a puppy, I would suspect hookworms or roundworms, but your veterinarian will need to do a physical examination to see what is happening.
What is a blood sample?
A blood sample is a sample given for medical purposes as a blood test.
What test identifies the organism associated with a urinary tract infection?
A urinalysis, or urine sample, is examined for both the presence of bacteria and white blood cells. After this, a urine culture to determine what bacteria is causing the infection may be done.
What are QBC blood analyzers?
In terms of blood analysis, "QBC" stands for "qualitative buffy coat". The buffy coat of a centrifuged blood sample contains the white blood cells of the blood, so a qualitative (numerical) analysis of the buffy coat is analogous to a differential white blood cell count in an uncentrifuged blood sample. A QBC blood analyzer is simply a machine that automatically performs these counts and presents the results to the physician or veterinarian.
