Cholelithiasis is usually diagnosed through imaging tests like ultrasound or CT scan. However, laboratory blood tests can show elevated levels of liver enzymes (such as alanine transaminase and aspartate transaminase) and bilirubin, indicating possible inflammation or obstruction in the bile ducts due to gallstones. These tests help in assessing the extent of liver involvement and determining the need for further diagnostic imaging.

On average, it takes about 3-5 days for alcohol to clear from your system and not be detected in an EtG test. However, this can vary based on factors such as the amount of alcohol consumed, individual metabolism, and overall health. Drinking plenty of water and staying hydrated can help expedite the clearance process.

A urinalysis typically involves three main tests: physical examination (color, odor, clarity), chemical analysis (pH, protein, glucose, ketones), and microscopic examination (white blood cells, red blood cells, bacteria, crystals). Additional tests may be included depending on the specific reason for the urinalysis.

A lipemic sample can interfere with the measurement of serum electrolytes by causing a falsely elevated potassium level due to the turbidity of the sample. Lipemia can also interfere with the accurate measurement of sodium, chloride, and bicarbonate levels in the serum. It is important to properly clear the sample of lipids before analyzing electrolytes to ensure accurate results.

Gray top tube is typically used for fasting blood glucose (FBG) testing.

Elevated mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) levels can indicate conditions such as vitamin deficiencies, liver disease, or anemia. It is important to consult a healthcare provider to determine the underlying cause and appropriate treatment.

The normal range for creatinine in human blood is approximately 0.6 to 1.2 milligrams per deciliter (mg/dL) for adult males and 0.5 to 1.1 mg/dL for adult females. Levels outside of this range may indicate kidney dysfunction.

It is important to follow the instructions given by your healthcare provider on whether or not you can take medication before a blood test. Some medications can interfere with the results of the blood test, so it's best to check with your healthcare provider first.

Yes, it is possible for two O Positive parents to have an RH Negative child if both parents are carriers of the Rh negative allele. This would result in the genetic combination needed for their child to be RH negative.

Hematology is the study of blood and blood-forming tissues, while lymph is a type of white blood cell that plays a role in the immune system. Lymphocytes are important in recognizing and fighting off infections and diseases. Hematology often involves analyzing the levels and types of lymphocytes in the blood to monitor a person's immune system health.

A red-top or gold-top tube is typically used for a Basic Metabolic Panel (BMP) test. It may vary depending on the laboratory or specific requirements, so it's always best to check with the specific facility where the test is being performed.

It is typically advised to avoid consuming coffee or tea when fasting before blood work, as they can affect certain blood test results (e.g., glucose levels). It's best to stick to plain water during the fasting period to ensure accurate test results.

A urine sample for kidney testing can typically be kept in a plastic container at room temperature for up to 24 hours. It should be securely sealed and stored in a cool, dark place to prevent contamination or deterioration of the sample. If the sample cannot be tested within 24 hours, it is recommended to refrigerate it or use a preservative to maintain its integrity.

The creatinine clearance test measures how well the kidneys are filtering waste products from the blood. It involves collecting urine samples over a period of time to determine the amount of creatinine excreted. This test is used to assess kidney function and detect any abnormalities.

LDL cholesterol, also known as low-density lipoprotein cholesterol, is a type of cholesterol that is often measured in a laboratory test to assess a person's risk of cardiovascular disease. Elevated levels of LDL cholesterol can lead to a buildup of plaque in the arteries, increasing the risk of heart disease and stroke. Lowering LDL cholesterol levels through lifestyle changes or medication can help reduce this risk.

The father could have blood types A, B, or AB as long as he is positive for the Rh factor. This is because the A blood type is dominant over O, so the offspring inherited the A allele from the father. The positive Rh factor could come from either parent.

Gray top tube (GTT) is typically used for glucose tolerance test.

The red top tube generally contains serum, which is the liquid portion of blood without clotting factors. Plasma, on the other hand, is obtained from blood collected in tubes with anticoagulants.

Yes, Fastin diet pills may contain ingredients that could potentially lead to a false positive result for amphetamines on a drug test. It is important to disclose any supplements or medications you are taking to the tester to avoid any confusion in the results.

Urine is typically sterile when it leaves the body, but it can become contaminated with bacteria if not handled properly. It is considered a waste product that the body eliminates to get rid of excess water and chemicals. Additionally, urine can be a source of germs and should be disposed of properly to avoid contamination.

The Coulter counter is based on the principle of detecting and counting particles suspended in a conductive liquid as they pass through a small aperture. As each particle passes through the aperture, it disrupts the flow of current, creating a detectable pulse that is used to count and size the particles.

The typical ratio of K2 EDTA to blood is around 1:9, meaning 1 part of K2 EDTA is used to collect 9 parts of blood. This anticoagulant helps preserve the blood sample by chelating calcium ions to prevent coagulation.

No, O positive and AB positive blood types are different. O positive is type O blood with the Rh factor, while AB positive is type AB blood with the Rh factor. Blood type is determined by the presence or absence of antigens on the surface of red blood cells, which is not interchangeable between O and AB types.

An AST (aspartate aminotransferase) value lower than the minimum range in a blood test may indicate a potential deficiency or an underlying health condition impacting the liver or heart function. Further evaluation by a healthcare provider is recommended to determine the cause and appropriate treatment.

Blood clumping, or agglutination, occurs when blood cells clump together due to the presence of antibodies that react with antigens on the surface of the cells. This can happen during incompatible blood transfusions or in certain autoimmune diseases where the immune system mistakenly targets its own blood cells.
