Laboratory Testing

Inverting a tube of blood will not prevent it clotting. Only an anticoagulant will do this, the different coloured tops on blood samples refer to the different anticoagulants or lack thereof inside the tubes. Inverting the tube is done to mix blood samples that have settled gently inverting the tube 6-10 times is enough to mix the blood. Inverting the tube more than this or doing it too violently could trigger clotting even in a sample containing an anticoagulant.

Blood is collected in a plain tube to obtain a serum sample. The absence of additives in a plain tube allows blood to clot naturally, separating the liquid serum from the solid components of the blood. This serum can then be used for various diagnostic tests.

A loop is sterilized by inserting it into a Bunsen burner flame until it is red hot.

1) This will incinerate any contaminating organisms that may be present.

2) This will ensure that viable cells are transferred.

The 10 tests routinely done during a urinalysis include physical examination (color, clarity), chemical examination (pH, protein, glucose, ketones, nitrites, leukocyte esterase), microscopic examination (urine sediment), specific gravity, and urine culture.

The "d-component" in urine may refer to various compounds derived from metabolized foods, drugs, or metabolic processes in the body. These components are filtered by the kidneys and excreted in urine as waste products. The specific d-components in urine can vary depending on an individual's diet, hydration status, and overall health.

Yes, it is usually recommended to fast for 8-12 hours before a full blood chemistry test to get accurate results, as eating can affect certain levels in the blood, such as glucose and triglycerides. Be sure to follow any specific instructions provided by your healthcare provider.

The color tube used for FDP (Fibrin Degradation Products) testing is typically a light blue top tube, which contains sodium citrate as an anticoagulant. This tube is used for coagulation studies to prevent blood from clotting.

The tube tops can vary depending on supplier, but red top is normally with no anticoagulant so it is used for any tests requiring serum not plasma, so most virology and biochem tests. Not usually used for Haematology tests.

Misplaced themometer, put the head of the thermometer too high (above the still head) the reading will be low, too low and the reading will be high. Badly greased joints, you could lose vapor. Not using cool water in the condensor and the vapor won't condense, and again you could lose vapor of the more volitile compound.

HGB in a hematology analysis report stands for hemoglobin. It is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. The HGB level is used to diagnose and monitor different types of anemia and other blood disorders.

A burette is a long, graduated glass tube used in analytical chemistry for delivering variable and precise amounts of liquid. It is commonly used in titration experiments to accurately measure the volume of liquid added to reach the endpoint of a reaction.

The free light chains test is typically done using a lavender-top tube. This tube contains EDTA as an anticoagulant and is suitable for plasma collection.

The Eos most likely mean you may be allergic to something - Mine are the same as yours and I am allergic to my two cats.

Eosinophils are white blood cells active in allergic diseases, parasitic infections, and other disorders. An eosinophil count may be ordered if the blood differential is abnormal, or if there is suspicion of specific diseases.

The eosinophil count may help your doctor:

* Detect an allergic reaction and assess its severity

* Detect a parasitic infection

* Evaluate Hodgkin's disease

* Assess sensitivity to drugs (particularly some anticoagulants)

* Confirm acute hypereosinophilic syndrome (rare but sometimes fatal leukemia-like condition)re...

what color tube is throat culture and what media plate

It is best to consult with your healthcare provider before taking any medication, including pain pills, before fasting blood work. Certain medications may affect blood test results, so it is important to follow your healthcare provider's instructions.

A lavender-top tube containing EDTA is typically used for ferritin testing. This anticoagulant is used to prevent clotting of the blood sample.

Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.

A gold or red/gray tiger top tube (serum separator tube) is typically used to collect a blood sample for a lipid panel test.

Yes. If the father is AO instead of AA (both of which are 'A' bloodtypes) and the mother is BO instead of BB (again, both simply called B), they can produce a child with type O blood.

Triglycerides are stored in adipose tissue, which is the body's main fat storage depot. Excess calories from food are converted into triglycerides and stored in adipose tissue for later energy use.

The types of urine specimens commonly used for testing include random urine, first-morning urine, clean-catch midstream urine, and 24-hour urine collection. Each type provides different information based on the timing and collection method.

A lavender/purple top tube is typically used for a full blood count (FBC) as it contains the anticoagulant EDTA, which prevents blood clotting and preserves the blood sample for accurate analysis.

A lavender-top tube is typically used for collecting samples for C-reactive protein (CRP) testing.

Yes, Levaquin (levofloxacin) is effective against a wide range of gram-positive cocci, including Staphylococcus aureus and Streptococcus pneumoniae. It is commonly used to treat infections caused by these bacteria.

The molecular formula for monosaccharides is CnH2nOn, where n is the number of carbon atoms in the molecule. Monosaccharides are simple sugars, such as glucose, fructose, and galactose, that cannot be hydrolyzed into simpler sugars.
