The first thing you should do after you put whole blood into a LTT.

What is invert 10 times?

100

These are the numbers of drops of whole blood and conjugate when preparing a SNAP test.

What is 3 drops of blood and 4 drops of conjugate?

100

This sample interference occurs when RBCs rupture.

What is hemolysis?

100

This test is specific to cardiac disease - specifically stretch and strain on the heart muscle.

What is proBNP (NT-proBNP)

200

The slide load order into the sample drawer for Chem18, TT4, and LYTE4?

What is LYTE4, then Chem18, then TT4?

200

This anticoagulant is commonly used in LTTs.

What is EDTA?

200

This is the minimum amount of time that a refrigerated SNAP test and conjugate should come to room temperature prior to using.

What is 30 minutes?

200

This sample interference appears milky/cloudy.

What is lipemia?

200

This test is proven to identify early kidney disease and imparied GFR and is also known as symmetric dimethylarginine. 

What is SDMA?

300

The minimum clot time for a serum separator tube.

What is 20 minutes?

300

These are the 3 parts of a CBC.

What is RBCs, WBCs, and PLTs?

300

The maximum amount of time that a SNAP test can be used once the pouch has been opened.

What is two hours?

300

This specific interference leads to low PLT counts and PLT aggregates.

What is clumping?

300

This diagnostic test is for monitoring diabetic control over the previous several weeks.

What is Fructosamine?

400

This is how long an opened LYTE4 clip is good for.

What is two minutes?

400

These are the three parts to a complete hematology evaluation.

What is numerical results, Dot Plots, and blood morphology?

400

SNAP tests are designed to detect the presence of these two proteins to create either a negative or positive result, using ELISA (enzyme-linked immunosorbent assay) technology.

What are antigens (proteins from the virus/parasite) and antibodies (proteins from the patient's immune system in response to an infection)?

400
This is the traditional fill order for a LTT, GTT, and RTT/SST.

What is RTT/SST, then GTT, then LTT?

400

This Reference Lab test may help identify infectious organisms by detecting their DNA or RNA rather than antibodies.

What is PCR?

500

This type of technology is used to make our Chemistry slides.

What is dry-slide technology?

500

This indicator on your in-house ProCyte result is letting you know that it did it's best to provide a numerical result, but you need to doublecheck the value with either blood morphology or Dot Plot review.

What is an *?

500

How you obtain a sample for a SNAP Parvo or SNAP Giardia test.

What is rolling fecal matter evenly onto the swab from either a provided stool sample, fecal loop, or unlubed gloved finger.

*NOT DIRECTLY FROM THE PATIENT*

500

This debris can sometimes can occur on a SNAP test if the SNAP Pro has not been cleaned recently.
