Laboratory Testing

It's generally recommended to avoid taking any medication before a fasting blood test, including angina medication, unless specifically instructed by your healthcare provider. This is to ensure accurate test results and avoid potential interference with the medication. It's best to consult with your healthcare provider for personalized guidance.

Usually a heparinized syringe is used for collecting venous blood gases. The blood can then be transferred into a light green tube (sodium heparin) or dark green tube (lithium heparin) for transport to the laboratory.

A red-top tube is typically used to test for herpes antibodies through a blood test. The blood sample is collected into the red-top tube, which does not contain any preservatives or anticoagulants. It is important to check with the specific laboratory or healthcare provider for their preferred collection tube.

The blood tube for prealbumin testing is typically lavender or purple. These tubes contain the anticoagulant EDTA, which helps preserve the sample for testing.

"PIT" on a blood test typically refers to "Platelet Immune Test," which is used to assess the presence of antibodies that may be causing low platelet levels or platelet dysfunction. It helps diagnose conditions such as immune thrombocytopenia.

High creatinine levels in the blood can be a sign of decreased kidney function or other health issues. It can indicate problems like kidney disease, dehydration, muscle breakdown, or certain medications. Monitoring creatinine levels regularly and addressing the underlying cause is important for managing kidney health.

A person who is B positive will have B antigens on their red blood cells and anti-A antibodies in their plasma. This blood type is compatible for transfusion with B positive, B negative, O positive, and O negative blood types.

The body maintains a balance called "acid-base balance", measured by blood pH. The average balanced pH is about 7.4 which is healthy for humans. The body does alot of things to keep this balanced, mostly using the lungs to get rid of acidic carbon dioxide and using chemicals from the kidneys (bicarbonate) to buffer or balance the pH.

Alkaline is the "base" or "basic" side of things. An alkaline pH would be anything over 7.45 such as 7.7, and at a certain point this becomes unhealthy. So alkalinity is what keeps the body from getting too acidic.

Having acidic conditions over long periods of one's life can raise the risk of cancers forming. Many manufacturers of health products and supplements claim that their veggie drinks or alkaline water/drinks can change blood pH. Eating lots of bitter leafy greens and vegetables and a balanced diet in general may give the body what it needs to do its job. Eating acidic foods which are way too common and prevalent in the modern diet can definitely make it harder to stay out of the acidic range- coffee, soft drinks, vinegar and cured or processed products have all been implicated. Sometimes food is intentionally made more acidic to keep bacteria from growing in the food.

But small amounts of supplementation over short periods are not likely to change serum pH significantly. But these are not as powerful as exercise, which promotes blood flow to the kidneys and causes accelerated elimination of carbon dioxide.

Now keep reading if you want to know about the nursing/medical knowledge behind this: ... the body can enter 4 types of imbalance: metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis. Metabolic conditions usually involve the body and the kidneys (CO2 will be normal here but other markers like bicarbonate will be high or low), and respiratory conditions involve the lungs and breathing (C02 will be high in acidosis or low in acidosis). Any of the above can be "compensated" (buffered by the kidneys that work to try and balance pH) or "uncompensated" (pH is unchanged because the kidneys aren't handling the situation).

Respiratory rates can change to hyperventilation or slow deep breathing which will change the the amounts of oxygen and carbon dioxide. All of this stuff is measured by a set of tests called "Arterial Blood Gases (ABGs)" which tell us everything we need to know to find out which of the above are going on. Sometimes something as simple as relaxation and deep breathing can bring a person back to balance, other times it's more complicated.

A creatinine level of 1.14 mg/dL is within the normal range for adults. However, normal ranges can vary slightly depending on the laboratory and individual factors, so it is best to consult with a healthcare provider for interpretation and any concerns.

A gray tube or plain red-top tube can be used for amylase testing. It is important to follow the specific specimen collection requirements of the laboratory where the testing will be performed.

A lavender or purple tube top is typically used for the Sedimentation Rate (sed rate) test as it contains the anticoagulant EDTA needed for the test.

An EtG test typically involves collecting a urine sample in a cup or tube. The sample is then sent to a laboratory for analysis. After the test is completed, results are usually reported as either positive or negative for the presence of ethyl glucuronide (EtG), a metabolite of alcohol.

A green-top vacutainer tube (or sometimes a pink-top tube) is typically used for collecting blood samples for lithium level testing. The green tube usually contains lithium heparin as an anticoagulant for plasma testing, while the pink tube may contain EDTA if plasma separation is not required. The specific tube color may vary depending on the lab's protocols, so it's best to confirm with the lab where the test will be performed.

Elevated levels of ALT and AST in a blood test suggest possible liver damage. ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes released when the liver is injured. Further evaluation by a healthcare provider is necessary to determine the underlying cause.

Anyone can marry anyone else if allowed by the person joining the couple together. The only problem that occurs is during pregnancy if the child inherits the positive blood from his father. This increases the risk of miscarriage and the mother will have to receive a shot. This is fairly common and in no way should affect whether or not a couple gets married.

The diameter of a creatinine molecule is approximately 0.7 nanometers.

It is generally recommended to fast for at least 8-12 hours before a fasting blood test to obtain accurate results. However, if your doctor specifically instructed you to fast for 16 hours, then you should follow their recommendation for the most accurate results.

The blood proteins A and B are antigens found on the surface of red blood cells that determine blood type. Individuals with blood type A have A antigens, while individuals with blood type B have B antigens. Blood type AB individuals have both A and B antigens.

Green top tube is used for GFR (glomerular filtration rate) testing, as it contains heparin as an anticoagulant and does not interfere with the test.

The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.

A light blue-top tube should be inverted 5-8 times after collection to ensure proper mixing of the blood with the anticoagulant. This helps prevent clotting and ensures accurate test results.

High Mean Corpuscular Volume (MCV) can be indicative of conditions such as vitamin B12 or folate deficiency, hypothyroidism, liver disease, or aplastic anemia. Treatment involves addressing the underlying cause, such as vitamin supplementation for deficiencies, hormone therapy for hypothyroidism, or managing liver disease. It is important to work with a healthcare provider to determine the specific cause and appropriate treatment plan.

The Direct Combs RH test typically requires a lavender/purple top tube, which contains EDTA anticoagulant to prevent blood coagulation. This type of tube is used for collecting blood samples for hematology tests, including the Direct Coombs test.

Enterobacter aerogenes is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium that is generally found in the human gastrointestinal tract. It is amylase negative.
