Laboratory Testing

A gold-top tube is typically used for a Complete Metabolic Panel (CMP) test. This tube contains a gel separator and clot activator to help with separation of serum during centrifugation.

Yes, but many say that it has draw backs when you do it. You can test surfaces that a person has handled after they many have handled drugs. Or you can use hair testing. some labs refuse to do this one because of the possible invasion of privacy ideas.

The color fuschia is called to test once a week at jams in Michigan, as per the Jam Testing Frequency regulations.

Smear microscopy of sputum is often the first TB test to be used in countries with a high rate of TB infection. Sputum is a thick fluid that is produced in the lungs and the airways leading to the lungs. A sample of sputum is usually collected by the person coughing. This very rapid and inexpensive but it does have a high false positive rate.
In 2011 the World Health Organization issued a policy statement recommending that conventional fluorescence microscopy should be replaced by LED microscopy. It also recommended that in a phased way, that LED microscopy should replace conventional Ziehl-Neelsen light microscopy. This method is slower and more expensive and may not be use as often as it should be.

Methylene blue discolouration measures the rate at which a material (usually soil) can reduce methylene blue dye. It is used to assess the dehydrogenase activity of microorganisms present in the material, providing an indication of soil microbial activity and overall soil health.

Centrifuge the serum separator tube (SST) for approximately 10 minutes at a speed of 1300-2000 revolutions per minute (rpm) to separate serum from other components.

No, thalassemia is a genetic blood disorder that affects the production of hemoglobin in red blood cells. Blood group and Rh factor are determined by different genetic markers and are not directly linked to thalassemia.

yes -- the real concern is the rh fator of mother/father/fetus and that is for the fetus' protection.

A green or dark green tube is typically used for collecting blood samples for bilirubin testing. These tubes contain heparin as an anticoagulant.

A royal blue-top or red-top tube is typically used for phenytoin testing. It is important to follow the specific instructions provided by the laboratory where the test will be performed.

The lavender or purple-top tube is typically used to measure iron levels in phlebotomy. This tube contains EDTA (ethylenediaminetetraacetic acid) as an anticoagulant to prevent clotting.

The gray top tube for urine culture typically contains a preservative, such as boric acid, to prevent the growth of bacteria in the urine sample during transportation and storage. This helps maintain the integrity of the sample until it can be processed in the laboratory for culture and sensitivity testing.

Biuret is a mild irritant and a substance of low toxicity, so it may cause irritation to the skin upon contact. It is important to immediately rinse the area with water to remove the substance and prevent further irritation. If irritation persists or worsens, it is advisable to seek medical attention.

Examples of immunoglobulins include IgG, IgA, IgM, IgE, and IgD. Each type of immunoglobulin plays a different role in the immune system, such as neutralizing pathogens, promoting immune responses, or triggering allergic reactions.

BUN stands for blood urea nitrogen, and it is a common laboratory test included in the metabolic panel. It measures the amount of urea nitrogen in the bloodstream, which can indicate how well the kidneys are functioning. Elevated levels may suggest kidney dysfunction or dehydration, while low levels may be seen in liver disease or malnutrition.

Both top inner and test are terms associated with software testing. "Top inner" typically refers to testing the internal workings of a software application, while "test" is a more general term covering various types of tests that can be conducted on software to assess its functionality and performance. Both processes are vital in ensuring the quality and reliability of a software product.

A person's blood group cannot change from O Rh- to another blood group. Blood types are determined by specific antigens present on red blood cells and these antigens do not change over time.

No, nanoparticles may not settle down when centrifuged because their small size and high surface energy can prevent them from fully separating or sedimenting. The interactions between nanoparticles and the surrounding medium can keep them suspended or dispersed even during centrifugation.

Abnormally high concentrations of protein in the urine, known as proteinuria, can be a sign of kidney damage or dysfunction. It may indicate conditions such as chronic kidney disease, glomerulonephritis, or diabetes. Further evaluation by a healthcare professional is necessary to determine the underlying cause and appropriate treatment.

To calculate the 24-hour urine creatinine, the amount of creatinine excreted in the urine over a 24-hour period is determined by collecting all urine passed during this time. The creatinine concentration in this pooled urine sample is then measured. Finally, the creatinine concentration is multiplied by the volume of the urine collected to obtain the total amount of creatinine excreted in a 24-hour period.

It is generally recommended to avoid consuming anything except water for at least 8-12 hours before a fasting blood test to ensure accurate results. Carbonated beverages like bubbly water may affect blood test results, so it is best to stick to plain water during the fasting period.

Gray top tubes with sodium fluoride/potassium oxalate additive should not be spun in the centrifuge as it can alter test results by causing hemolysis. These tubes are usually used for glucose testing and need to be kept upright to prevent mixing with cells.

The Corvac tube is a type of blood collection tube used to prevent clotting by containing an anticoagulant additive, such as EDTA or citrate. It is commonly used for collecting blood samples for various laboratory tests that require whole blood or plasma.

A lavender or pink-top tube is typically used for human growth hormone (HGH) testing.
