Laboratory Testing

nah man.

anyway you shouldn't be smoking.

Actually you can, if you are worried about it showing up in your bloodstream. Nicotine doesn't show up on a typical blood test, if at all. If you are worried about it, I think it may be time to quite. Good luck!

It would all depend on the Dominant and Recessive blood type genes in the mother and father it is near improbable to tell unless you take a blood sample to test the blood type. == A rhesus negative mother and positive father can produce either a rhesus negative or positive child. A type A and type O parental combination will only produce either type A or type O children. So an A- mother and O+ father will normally produce offspring having the possible blood groups of A+ or A- or O+ or O-. See the link for a full explanation.

It is not typically necessary to fast before a B12 test. B12 levels are not affected by food intake, so you can usually have the test done at any time. However, it's always best to follow any specific instructions given by your healthcare provider or the lab conducting the test.

A red-top tube is typically used for crossmatching blood. This tube contains no anticoagulant and is used for collecting blood samples for serology testing, including crossmatching.

A CPC (complete blood count) test provides information about the number and types of blood cells in your body, including red blood cells, white blood cells, and platelets. It can help diagnose conditions such as anemia, infections, and leukemia, and monitor the effects of certain medications or treatments on blood cell counts.

Bacterial smears are fixed before staining to adhere the bacteria to the slide and kill the bacteria, which helps to prevent them from washing away during the staining process. Additionally, fixing the bacteria helps to preserve their cellular structures and prevent distortion during staining.

The total iron binding capacity (TIBC) test typically uses a lavender or royal blue top tube, as it requires an EDTA anticoagulant to prevent clotting and preserve the sample for analysis.

A PT of 30.1 and an INR of 3.1 suggest the blood is taking longer to clot than normal, indicating a risk of bleeding. This is considered moderately elevated, and medical intervention or adjustment of anticoagulant therapy may be needed to prevent bleeding complications. It is important to consult a healthcare provider for further evaluation and management.

A lavender top tube is typically used to collect blood samples for homocysteine level analysis.

For a microhematocrit test, capillary blood, usually obtained from a finger or heel stick, is used. The blood sample is placed into a special capillary tube and spun in a centrifuge to separate the components, allowing for measurement of the packed cell volume (hematocrit).

The sticks contain enzymes (glucose oxidase and peroxidase) which react in the presense of glucose. The glucose oxidase changes glucose into gluconic acid and hydrogen peroxide and the peroxidase reacts with that hydrogen peroxide to change a pigment in the stick from neutral color to positive color.

An arterial blood gas (ABG) sample is typically drawn in a heparinized syringe, not a tube. The heparin coating prevents the blood from clotting, allowing for accurate analysis of blood gases.

A pH of 5.5 would be considered slightly acidic. Pure water has a neutral pH of 7, so a pH of 5.5 indicates that the solution is more acidic than neutral.

Antibiotics can lead to changes in the normal bacteria balance in the urinary tract, resulting in the presence of pus cells or white blood cells in the urine. This is a sign of inflammation or infection in the urinary tract, and it is important to follow up with a healthcare provider for further evaluation and treatment.

A gold or tiger-top tube is typically used for a gamma-glutamyl transferase (GGT) test. This type of tube contains a gel separator and clot activator, which helps with serum separation.

FBS (Fetal Bovine Serum) typically comes in amber-colored tubes to protect it from light degradation and maintain its quality. The amber color helps to block out harmful wavelengths that may affect the serum's stability and potency.

There are two reasons for this first is for safety. If the patient pulls the arm back when the needle is inserted the needle may recoil as it comes out of the arm, springing back into your finger. Also there is the possibility of contamination of the site that you just cleaned.

Neutrophils are a type of white blood cell that fight infection and kill microorganisms. Some causes of a low supply of neutrophils are congenital diseases related to the bone marrow, leukemia, radiation and chemotherapy.

For a PSA blood test, it's generally recommended to fast for a few hours beforehand to ensure accurate results. It's best to follow your healthcare provider's guidelines for fasting before the test.

Creatinine levels can decrease due to various reasons such as decreased muscle mass, reduced protein intake, or certain medications affecting kidney function. It's important to consult a healthcare provider to determine the specific cause and manage any underlying conditions.

Fasting is generally not required before a B12 blood test. However, it is always best to follow your healthcare provider's specific instructions when preparing for any type of blood test.

Generally, a serum electrolyte test does not require fasting. However, some healthcare providers may request fasting if additional tests are being performed along with the electrolyte test. It is best to follow the fasting instructions provided by your healthcare provider.

The father can have either A, B, or O blood types, but not AB. There are two alleles in the genotype that determine a persons blood type, and A and B are co-dominate with O as recessive. For example, you have 'B' type blood. In order to have that your genotype can either be BB or BO, but because you son is a type 'O', then you have must have BO blood. When the chromosomes in your sex cells split, one got only the 'B' allele, while the other only received the 'O', your son specifically received the 'O'. The same is the case for the father, the specific sperm that fertilized the egg had an 'O' allele from the father. So the father does not have AA BB or AB blood, but he may have AO BO or OO. For reference an example of an allele would be A, or B or O, and example of a genotype would be AA or AO or BB or OO and so on.

EDTA test tube (Lavender top) for CBC etc.

Heparinized test tube (Green top) for CD4 and absolute lymphocyte count

Sodium floride(Grey top) for sugar test.

It's generally best to stick to water only before fasting blood tests to ensure accurate results. Certain teas, especially those with caffeine or additives, could potentially affect blood sugar or lipid levels, influencing test results. Be sure to follow your healthcare provider's specific fasting instructions for the most accurate results.
