What is a precipitin test used for?
A precipitin test is used to determine if someone has been exposed to a specific antigen by detecting the presence of antibodies in their blood. This test is commonly used to diagnose certain infections or to confirm exposure to allergens.
What is the biochemical test for methanogen?
One common biochemical test for methanogens involves measuring methane production in the presence of a substrate such as acetate, methanol, or hydrogen. Methanogens typically produce methane gas as a metabolic byproduct, which can be quantified using gas chromatography or other analytical techniques.
What is a methane burp?
Not sure if I'm on the right track but... Way back in the '70s when I did chemistry, the 'standard' test for methane was to collect a small sample in a test tube, hold the mouth of the tube near a naked flame, and wait for it to 'pop'. The thing is - that also worked for any other combustible gas - such as oxygen !... If I'm wrong - someone else is more than welcome to remove this and replace it with the right answer. <><><><> Actually, the term Methane Burp is a theory to account for massive global climate change. One theory is that a change is ocean temps (or levels) can trigger a large scale release of methane from compunds called methane clathrates on the sea beds. Methane (being a powerul greenhouse gas) would cause a rise in air temps. One theory is that a methane burp brought about the death of the dinosaurs.
What is the principle behind alkaloidal test?
The principle behind alkaloidal tests is based on the ability of alkaloids to form specific chemical reactions or complexes when exposed to certain reagents. These reactions can help in identifying the presence of alkaloids in a given sample by producing characteristic color changes or precipitation. Common alkaloidal tests include Dragendorff's test, Mayer's test, and Wagner's test.
Is the flame test lab a destructive or non-destructive test?
The flame test lab is a non-destructive test because it does not destroy the sample being tested. It involves observing the color of the flame produced when a sample is exposed to heat, which can help identify certain elements present in the sample.
How can I be tested for HPV?
A Pap smere from your gynocologist is the best way to find out if you have been exposed. You can visit your gynocologist to have this test done.
What is a negative test result for a TB test?
In people who have not been exposed to TB, there will be little or no swelling at the test site after 48-72 hours. This is a negative test result.
What do you do for a 2 year old dog that has been exposed to parvo?
Request a titre blood test at your vet to find out your dogs immunity level to Parvo and watch closely for symptoms.
If you had a weak positive antibody test to hepatitis C but are not infected with it nor been exposed ever can you then get a negative result in another test or will it always be confused?
no
How can one test for methane gas in water?
One can test for methane gas in water by using a methane gas detector or sensor specifically designed for water testing. These devices can detect the presence of methane gas in water samples, providing a reliable way to measure its concentration.
At what age can children receive the purified protein derivative test?
This is the test for tuberculosis. Definately ask your doctor. It all depends on risk. Do you think the child has been exposed to tb? Then you would need to know if he/she has been infected. Exposure is not one in the same with infection. If the child has been exposed, and is infected, the sooner the diagnosis can be made, then the sooner treatment can be started. I don't think there is a minimum age for this test in children. It just depends on risk, whether the child may have been exposed. Better safe than sorry. Oh, and the test for tb is with inactivated bacteria, so don't worry that the test would cause infection. Call your doctor! Hope this helps.
In what year was a blood test to detect HIV founded?
The first test licensed for HIV testing was the ELISA test in 1985. ELISA detects antobodies to the HIV virus, which indicates that the person has been exposed to the virus.
How can one effectively test for methane gas in a given environment?
To effectively test for methane gas in a given environment, use a portable methane gas detector or sensor. These devices can detect methane levels in the air and provide immediate readings. Make sure to follow safety guidelines and calibrate the detector regularly for accurate results.
Is it possible for a child hair strand test to test positive?
You have not said positive to what. If you mean drugs then yes, if the child has taken drugs, been breast fed by someone on drugs or been exposed to secondary drug smoke etc.
What is a mono blood test?
A mono blood test is a laboratory test to detect antibodies that are produced in response to the Epstein-Barr virus (EBV), which is the virus that causes infectious mononucleosis. This test helps diagnose mono by determining if a person has been exposed to the virus.
What is a precipitin test used for?
A precipitin test is used to determine if someone has been exposed to a specific antigen by detecting the presence of antibodies in their blood. This test is commonly used to diagnose certain infections or to confirm exposure to allergens.
What is 0.0277 as a fraction?
You know, looking up answers for a math test is brutal. Not only are you cheating, but you have just been exposed. Your teacher has just been notified about you cheating.
