Laboratory Testing

A lavender or royal blue tube is typically used for collecting a TIBC (total iron-binding capacity) test.

The 'c' on a urine test typically refers to the concentration of the urine sample. This concentration is measured to assess the urine's specific gravity or how dilute or concentrated it is. It can indicate hydration levels or certain medical conditions.

A toxicology blood test, also known as a toxicology screen, is a test that analyzes blood samples to identify the presence of drugs or alcohol in the body. It is commonly used in emergency medicine, forensic investigations, and workplace drug testing to assess drug use or poisoning.

After collection, a EDTA tube should be inverted several times gently to ensure thorough mixing of the blood with the anticoagulant. This helps prevent clotting and ensures proper preservation of the sample for analysis.

The tube for CPK (creatine phosphokinase) isoenzymes is typically red or gold, depending on the laboratory.

If you have the correct testing strips you could test yourself for blood in your urine. If the test is positive you should see your medical care provider as soon as possible so she/he can do follow up tests do determine the cause of the bleeding.

Yes. It would be rare, however. In this case, the father has the antigen for either type A or B blood. The antigen is not however connected to the H antigen (this is the part that makes him express the O type). If it were connected to the H, he would be either A or B. Therefore, it is possible that his child could receive his antigen and the opposite from the mother in order to be AB type.

A urine creatinine level of 47 is considered low and may indicate kidney dysfunction or muscle loss. It is important to consult with a healthcare provider for further evaluation and any necessary follow-up testing.

Creatinine of 1.0 would be in the normal range. Creatinine levels in the blood range from 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females.

For measuring parathyroid hormone (PTH) levels, a lavender or royal blue top tube is usually used for blood collection. These tubes contain the necessary additives to preserve the sample for accurate testing.

A centrifuge spins things outward, causing particles in a mixture to separate based on their density. The high centrifugal force pulls denser particles to the outer edge of the rotating container while lighter particles move towards the center.

The normal range for the BUN to creatinine ratio is typically between 10:1 to 20:1. A ratio of 24.1 may indicate dehydration, a potential kidney issue, or other health conditions. It is important to consult a healthcare provider for a proper evaluation and interpretation of the results.

A creatinine level of 0.74 mg/dL is within normal range for adults. However, normal levels can vary depending on age, gender, and muscle mass. It's important to consult with a healthcare provider for proper interpretation of creatinine levels in context of overall health.

No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.

Fasting is typically not required for an electrolyte panel test. It is recommended to follow any specific instructions given by your healthcare provider, but in general, electrolyte levels are not significantly affected by food intake.

No, a higher MIC (minimum inhibitory concentration) on a urine culture indicates decreased susceptibility to the antibiotic being tested. Ideally, a lower MIC value indicates better susceptibility to the antibiotic.

Typically, a blood draw tube is filled with about 8-10 milliliters of blood. The amount can vary depending on the specific tests being performed and the size of the tube. The phlebotomist will usually fill the tube to the required volume indicated on the tube label.

O positive and O negative can only receive from the same type of O. O is considered to be a universal donor, while AB is considered to be a universal receiver. A however, is neither, which means that it can only receive from O and other A's.

Any A blood group has antigen b, while any O has antigen a and b. When a person with blood group A transfer the blood to O, antigen b from both sides meet and co-aggutation occurs (i.e the blood clotts within the receiver). this act can be fatal

The recommended tube for dilantin (phenytoin) is a red-topped tube, which indicates that it should be collected in a tube without anticoagulant. It is important to follow specific collection instructions as provided by the laboratory or manufacturer.

No, tiger top and red top are different types of blood collection tubes. Tiger tops have a serum separator gel and clot activator for biochemical testing, while red tops contain no additive and are used for various tests like cholesterol and blood glucose.

The recommended tube for collecting samples for H. pylori testing is a yellow-capped tube. This tube typically contains a preservative that helps maintain the integrity of the sample during transportation to the laboratory. It is important to follow the specific instructions provided by the laboratory for collecting and handling the sample to ensure accurate test results.

No, fasting is not necessary for a glycohemoglobin A1C test. This test measures your average blood sugar levels over the past 2-3 months, therefore it is not affected by short-term changes in diet or fasting.

Yes, a SST (serum separator tube) can be used for digoxin level testing. It's important to separate the serum from the cells promptly after collection to prevent interference with the assay. Following proper sample handling procedures will ensure accurate results for digoxin level measurement.

For iron panel tests, the test tube typically used is a lavender or purple-topped tube. These tubes contain an anticoagulant and are used for collecting whole blood samples for hematology tests including iron panels.

Methyl alcohol in Leishman's stain serves as a solvent to help dissolve the dyes and other components in the stain solution. It also functions as a fixative to help preserve the cellular structures of the sample being stained.
