Laboratory Testing

Creatinine is typically drawn in a lavender or green-top tube. The specific color may vary depending on the laboratory or facility. It is important to always follow the specific instructions provided by the facility where the blood test is being done.

The recommended tube color for collecting blood samples for AST or ALT tests is a plain red top tube without any additive. This allows for serum separation.

A lytes panel typically requires a green or lavender top tube as it needs to be collected in a tube with an anticoagulant. This is to prevent the blood from clotting and altering the electrolyte concentrations being measured in the sample.

The preferred tube for collecting blood for an A1C test is a lavender/purple top tube, which contains the anticoagulant EDTA. This tube is used to prevent blood from clotting during testing.

Blood group O is caused by a recessive gene (symbol: i). The mother must therefore be homozygous (ii). The offspring must, like Mum, have two copies of the recessive gene, and one of these must have come from Dad. So the father's possible genotypes are IAi (blood group A), IBi (group B), and ii (group O), all of which include a recessive gene that could be passed on to the offspring.

The color tube for bilirubin direct is usually a green or dark green tube.

Yes, it is possible for an A positive mother and a B positive father to have an O negative child. This can happen if both parents are carriers of the O negative blood type, which can be inherited from ancestors. In this case, the child would inherit one O gene from each parent, resulting in an O negative blood type.

A grey tube typically contains blood samples that are collected for laboratory testing. The grey top tube contains an additive called sodium fluoride and potassium oxalate, which are used to preserve glucose levels in the blood sample.

Lavender top (EDTA) tube is typically used for drawing blood for a reticulocyte count. This tube is commonly used for hematology tests because it contains an anticoagulant (EDTA) which helps preserve the blood sample.

An A1 person is an A person. A people are primarily A1 (about 80%) and A2 (20%). There are quantitative and qualitative differences between A1 and A2, but for almost all intents and purposes, these people are blood type A and would receive A red blood cells.

(p.s. the negative just means Rh (D) negative)

The patient is instructed to fast for 12 hours before the blood test to get an accurate measurement of the glucose level. Eating or drinking before the test can affect the results and lead to inaccuracies. Following the fasting instructions helps ensure the test provides valuable information about the patient's glucose levels.

A lab test that may not be typically conducted if a patient has suspected plaque would be a blood test. Plaque is mainly assessed through physical examination of teeth and gums, dental X-rays, and periodontal probing. A blood test is more commonly used to detect systemic conditions related to oral health, such as diabetes or vitamin deficiencies.

A PSA test is typically collected in a lavender-top tube, which contains the anticoagulant EDTA.

A lavender-top tube should be used to collect a fasting prolactin level sample.

CXR stands for "chest X-ray," which is a type of imaging test to visualize the organs and structures within the chest cavity, including the lungs, heart, and bones. It is commonly used to diagnose conditions such as pneumonia, tuberculosis, and lung cancer. It does not stand for a blood test.

KC stands for "potassium citrate," which is a compound used as an anticoagulant in blood tests to prevent the blood sample from clotting.

A creatinine level of 88 is within the normal range for adults, which typically falls between 0.6 to 1.2 mg/dL. However, it's important to consider other factors such as age, gender, muscle mass, and underlying health conditions when interpreting creatinine levels. If you have concerns about your creatinine level, it's best to consult with a healthcare provider for further evaluation.

Yes, it is recommended to fast for 8-12 hours before having a blood test to check depakote level, unless otherwise instructed by your healthcare provider. Fasting helps ensure accurate results by preventing any interference from food or beverages. Be sure to follow any specific instructions provided by your healthcare provider.

A sample of vomitus is typically collected when there is suspicion of poisoning or infection causing nausea or vomiting. Serum creatinine levels are checked to assess kidney function, especially in patients with known kidney disease, high blood pressure, or diabetes.

This is something you should cover with your doctor before the test.

According to both Healthline and MedlinePlus, you should not eat or drink within the 8 hours before the test. That's why many people schedule such tests for first thing in the morning.

If you are taking medication, ask your doctor if you should discontinue them prior to the test.

Platelet function studies are typically collected in a blue-top tube (sodium citrate) to prevent clotting and maintain the function of platelets for analysis.

A centrifuge flings things outward. The centrifugal force causes particles to move away from the center of rotation and settle at the periphery, separating substances based on density or size.

A basic metabolic panel (BMP) typically uses a green-top tube for blood collection. This tube contains a lithium heparin additive to prevent clotting and is suitable for most chemistry tests included in a BMP.

The fourth color Vacutainer tube in the order of blood draw is typically the green-top tube, which contains lithium heparin as an anticoagulant. It is usually used for chemistry tests that require plasma.
