Laboratory Testing

RH factor in blood types stands for "Rhesus Factor". Blood tests were performed on Rhesus monkeys and the Rh+ and Rh- factors were isolated. An antigen found in the red blood cells of most people: those who have Rh factor are said to be Rh positive (Rh+), while those who do not are Rh negative (Rh-). What about the meaning of RHD- Rh blood group, D antigen . The rhesus complex is not just one antigen, but several, when someone is told to be Rh+, it usually refers to the D antigen (one of the components of the Rh complex), because it's the most common, and the easiest to identify, however it's not the only one.

I would say no, since the medicine, depending on what it is for, might change your blood readings and it might not be the readings that you want.

I mean, you can, but just keep that in mind.

A blue or lavender tube is typically used for beta-2 microglobulin testing. Make sure to consult with your healthcare provider or testing facility for specific color coding protocols.

A creatinine test is a blood test that measures the level of creatinine in your blood. Creatinine is a waste product produced by the muscles, and the test is commonly used to assess kidney function. High levels of creatinine in the blood may indicate reduced kidney function.

To type blood according to abo, the lab detects the proteins of the cells to determine whether blood is a b or o. To further type blood into rh- and rh positive, the lab checks antibodies to specific proteins.

It is possible for a small amount of alcohol, such as one swallow, to be detected in an EtG urine test, especially if the test is conducted within 24-48 hours of consuming alcohol. The detection window can vary depending on individual factors such as metabolism and hydration levels.

A SST (serum separator tube) typically has a gold or tiger top color, which indicates that it contains a gel separator to separate serum from blood cells during centrifugation. This type of tube is commonly used for collecting blood samples for various laboratory tests.

Yes, each heme group within hemoglobin contains an iron atom that binds to a single oxygen molecule. Hemoglobin as a whole can carry up to four oxygen molecules at a time, with each of its four heme groups binding to one oxygen molecule.

A trace amount of protein in the urine on a urinalysis means that there is a very small amount of protein present, which is not typically concerning. However, it is important to follow up with your healthcare provider to rule out any underlying kidney issues or to monitor for changes in the future.

A homocysteine blood test measures the level of homocysteine in your blood. Homocysteine is an amino acid that plays a role in heart health, and high levels have been associated with an increased risk of cardiovascular disease. The test can help assess your risk for heart disease and may be recommended for certain individuals with a family history of heart problems.

The color tube for a serum iron blood test is typically a gold or red-speckled/gray-stopper tube, which is specifically designed for collecting blood for serum tests. It is important to confirm with the laboratory or healthcare provider regarding the specific tube color and collection instructions for the test.

The test for alkaline phosphatase isoenzyme is typically performed using a lavender or pink tube, which contains EDTA as an anticoagulant. The choice of tube color may vary depending on the laboratory and manufacturer, so it's best to confirm with the specific lab where the test will be conducted.

A high creatinine serum level typically indicates impaired kidney function. The kidneys remove creatinine from the blood, so elevated levels can be a sign of decreased kidney filtration or other kidney problems. It is important to consult a healthcare provider for further evaluation and treatment.

SST (Serum Separator Tube) and Red Top tubes generally require 30-60 minutes of clotting time before centrifugation. This allows the blood to coagulate and separate into serum. It is important to follow the specific protocol provided by the manufacturer or laboratory for accurate results.

A basic metabolic panel typically includes tests for glucose, electrolytes (such as sodium, potassium, and chloride), kidney function (such as blood urea nitrogen and creatinine), and sometimes includes tests for calcium and bicarbonate levels.

Yes, a child can be B negative if one parent is A negative and the other parent is AB negative. The child would inherit one negative Rh factor from each parent, resulting in a B negative blood type.

I think so......... I am not sure. So, I guess it's possible for it to happen. Yeah..... I'm pretty sure it is...... So........ Yeah, I guess they can.

The color of the tube used to draw a blood urea nitrogen (BUN) test is typically purple or green. The specific color can vary depending on the laboratory or healthcare facility's protocol.

A grey top tube is typically used for lactic acid testing as it contains sodium fluoride as a preservative.

It typically takes a few days to a week to receive A1c results. The test is usually sent to a laboratory for analysis, and the results are then sent back to the healthcare provider who ordered the test.

A urine culture typically takes 24-48 hours to show initial results, which may indicate the presence of bacteria. If bacteria are present, a sensitivity test to determine which antibiotics are effective against the specific bacteria can take an additional 24-72 hours. Overall, the process can take anywhere from 1 to 5 days.

Lactulose, a laxative commonly used to treat constipation, is unlikely to affect the results of an Ethyl Glucuronide (EtG) test, which is used to detect recent alcohol consumption. EtG is specific to alcohol and is not known to be influenced by medications like lactulose.

A centrifuge uses rotational force to separate materials of different densities. When the centrifuge spins rapidly, the denser materials move towards the outer edges due to centrifugal force, causing them to separate from lighter materials that remain closer to the center.

Yes, creatinine is freely filtered by the glomerulus and not reabsorbed by the proximal convoluted tubule (PCT). It is mostly excreted in the urine and its levels can be used as a marker of kidney function.
