Question:

What are the conditions required from the patient when we are measuring D-dimer and what are the uses and basic recommendations of this test?

Answer:

The orient should be fasting for at least 8 hours due to probable interference with the result, giving either False Negatives or False Postives. D-dimer is commonly used to diagnose Pulmonary embolism, that is why it’s adviced that this test should be required only when there’s is a suspicion of Thrombosis or Intravasculation Coagulation, given the many false positives and negatives.

Answer:

If you remember, Gram Negative Bacteria will be present, when dyed (Gram Tecnique), will present the color Red and Gram Positive the color Purple. This is due to the composition of the cell walls. Imagine you have two sandwiches one thicker than the other! The slimmer on is composed only of bread, mayonnaise, cheese and ham. The second one has the same ingredients but added tomatoes, lettuce and avocado! Now the lettuce, compared to the bacteria, would be what we know as Peptoglycan. What This does is creates a complex along side Iodine, that is stains the cell wall of the Gram positive bacteria but not the Gram Negative Bacteria since this last one has a very thin layers of peptoglycan.
