Laboratory Testing

A lavender tube is typically used for a complete blood count (CBC), which includes hemoglobin and hematocrit measurements. These measurements are part of the "h and h" test.

the body will produce the anti D- antibodies which are going to attack the RH+ blood of the donor

usually the first time is not a threat since the formed antibodies are IgM class which has a very low conc.

the second time is very dangerous due to the formation of memory cells that are activated in the second blood transfusion leading to the production of IgG antibodies in very high conc. leading to the agglutination of the blood and severe anemia

Order to draw: Multiple tube collections - YELLOW --Blood cultures ...SPS (most sterile specimen) inversion is 8-10 times, LT BLUE --contains sodium citrate inversion is 3-4 times, RED/GOLD ...SST Gel Separator tube inversion 5 times, RED --No Additives, GREEN -- (this tube is only used in Hospital draws) Heparin (blood thinner) tube inversion 8-10 times, LAVENDER/PURPLE -- EDTA (anticoagulant) tube - inversion 8-10 times, GRAY -- Oxalate Fluoride (glucose) tube inversion 8-10 times.

A low CH (cholesterol) CM (micromolar) level in blood tests for children could indicate a potential concern with lipid metabolism, malnutrition, or liver disease. It is important to consult with a healthcare provider for a proper evaluation and further testing to determine the underlying cause.

The child could be either blood group A with Rh positive or blood group B with Rh negative. Both A and B are possibilities since the father has blood group O and can pass on either the A or B allele. The Rh factor (positive or negative) will depend on the mother’s AB- blood group.

The three major components of a routine urinalysis are physical examination (color, clarity, volume), chemical examination (pH, protein, glucose), and microscopic examination (red blood cells, white blood cells, bacteria).

A red-top tube is typically used to draw blood for a vancomycin trough level. However, it is important to follow the specific instructions provided by the healthcare provider or laboratory.

The tubes used for cardiac enzyme blood draws are typically red or tiger-topped tubes, which contain a clot activator and a gel separator. These tubes are used for testing cardiac enzymes like troponin, creatine kinase (CK), and CK-MB levels.

Alcohol does not actually stay in urine for very long. It should be completely gone in about 80 hours from consumption. There is no real way to rush it, as your liver has to metabolize it. There are cleanses and detoxes that claim to get rid of it sooner, but they do not actually work. All they do is make you pee a lot. Since it is your liver doing the work, not so much your kidneys, this really is not effective.

SST blood tube stands for serum separator tube. It contains a gel that separates the serum from other blood components after centrifugation, making it easier to collect and test the serum.

It's best to avoid taking laxatives while fasting for a blood test, as it can affect the accuracy of the results. Laxatives can alter electrolyte levels in the blood, which may impact the test results. If you have concerns about taking laxatives, it's important to consult with your healthcare provider for guidance.

Both a barium swallow and a barium meal test involve you swallowing a liquid suspension of barium sulphate before a series of X-rays are taken of your upper digestive tract. In a barium swallow test, X-ray images are taken of your pharynx (throat) and your oesophagus (the passageway that connects your throat to your stomach; sometimes called your gullet).

In a barium meal test, X-ray images are taken of your stomach and the beginning of your duodenum (the beginning of your small intestine, the passageway that takes food away from your stomach). A barium meal test is often performed straight after a barium swallow test.

Barium is a naturally occurring element that appears white on X-ray. In these tests, the barium is given as a cup of flavoured drink - like a milkshake. When swallowed, barium coats the walls of the digestive tract, which allows the shape of your upper digestive tract to be outlined on an X-ray. Without the barium your upper digestive tract would be barely visible on X-ray.

A comprehensive metabolic panel is typically collected in a green or tiger-top (serum separator) tube. It is important to follow the specific collection instructions provided by the laboratory or healthcare provider to ensure accurate results.

A leukocyte esterase result of 1+ indicates the presence of white blood cells (WBCs) in the urine, suggesting a possible urinary tract infection. A WBC count of 0-5 is within the normal range, but in combination with leukocyte esterase positivity, it may indicate an early infection or inflammation in the urinary tract. Further evaluation and follow-up may be needed to determine the cause.

Yes, it is possible for a mother with O blood type and a father with A blood type to have a baby with B blood type. This is because the A and B blood type alleles are dominant over the O blood type allele, allowing for the B blood type to be expressed in the offspring.

If a lavender tube is collected before a light green tube, there is a risk of contamination and carryover of additives present in the lavender tube into the sample collected in the light green tube. This can affect the accuracy of test results and potentially lead to erroneous findings. It is important to follow the correct order of draw to ensure the integrity of the samples.

"On the down low" means to keep something secret or to keep it quiet or discreet. It typically refers to not sharing information widely or keeping something confidential.

It is generally safe to take throat lozenges before a blood test, as they are not likely to interfere with the results. However, it is always a good idea to inform the healthcare provider performing the test of any medications or supplements you have taken beforehand.

I would need more information (like what blood types the child's grandparents are) to narrow it down. The child could be:

- A negative

- A positive

- AB negative

- AB positive

- B negative

- B positive

You would typically use a light blue-top tube containing sodium citrate for coagulation testing. This type of tube is used to prevent blood from clotting by binding calcium ions, which are essential for the coagulation process. It is important to fill the tube to the proper fill line to maintain the correct blood-to-anticoagulant ratio.

No, that's not true. If you are a Rh- mother then your immune system will become sensitized by an Rh + baby and if you were to have a second Rh+ baby without taking medication to control this then that baby would have a condition called fetal erythroblastosis.

A common hematology lab test used by the CDC is the complete blood count (CBC). This test provides information about the cells in the blood, including red blood cells, white blood cells, and platelets. It can help detect a variety of conditions such as infections, anemia, and blood disorders.

Step #1: First, you must tare the balance. That means setting the mass to zero when there is nothing on it. A digital scale will have a button marked "tare" and you just push it, but on a triple beam balance, you must do some find adjustments to get the indicator to float in the middle.

Step #2: Then weigh the mass of the container(empty) of the chemical sample. For a digital balance, just put the container on the balance and read the number on the display. For a triple you need to move the weights along the bars until the indicator is floating in the middle of the marks (just as you did to tare it). If not using a container, you should always use a dish or weighing paper, and you should weight that first also. Mark down this answer as you will need it later!

Step #3: Then add your sample to this container or the weighing paper. Repeat just as above and determine the total mass of your sample plus the container.

Step #4: Finally, simply subtract the weight you got in step #3 from the one in step #2. This will give you the weight of the sample alone without the container.

"1+ with your blood" means there is a small amount of blood in your urine sample. This could be due to many reasons, including urinary tract infections, kidney stones, or strenuous exercise. Further evaluation by a healthcare provider may be needed.

A lavender/purple top tube is typically used to draw blood for a hematocrit test. This tube contains the anticoagulant EDTA, which helps prevent the blood from clotting during testing.
