Answers to common questions
Use these resources to answer your questions about the SediVue Dx
What species are supported on the SediVue Dx Urine Sediment Analyzer?
The SediVue Dx software algorithms have been developed and validated using canine and feline urine samples. Other species and/or sample types may be loaded into the SediVue V70i Cartridge, but the results will only include the digital images captured during the run.
How many and what elements can the SediVue Dx analyzer identify?
The SediVue Dx analyzer has the ability to identify 13 of the commonly found formed elements:
- Red blood cells (RBCs)
- White blood cells (WBCs)
- Squamous epithelial cells
- Nonsquamous epithelial cells
- Hyaline casts
- Nonhyaline casts
- Struvite crystals
- Calcium oxylate dihydrate crystals
- Ammonium biurate crystals
- Bilirubin crystals
- Unclassified crystals (all other)
How long does it take to run a sample?
The run time varies based on the types and concentrations of formed elements in the sample. The vast majority of samples will be done in less than 3 minutes.
Will the results and images transfer to VetConnect PLUS?
Yes, the results will be available in tabular form along with the first 3 or up to 6 images and combined with the urine chemistry and physical evaluation results. Use results in conjunction with previous reference laboratory results for a complete patient history. Trend graphs are not available because of the role collection method and specific gravity play in determining the relative and acceptable concentrations of each formed element. Prioritized images will appear in VetConnect PLUS (up to 6 total).
How fast and for how long does the centrifuge spin?
The centrifuge spins at 2,000 RPM for 30 seconds (10 seconds for quality control [QC] runs) or 260 g.
How can you get good results with just 165 µL?
The efficacy of traditional methods is acceptable but confirmed suspicious that there are undesired destruction and inconsistent concentration of many important formed elements.1 The gentle centrifugation and highly standardized processes cause much less damage and a more uniform distribution of formed elements. Once prepared, the SediVue Dx analyzer scans more than 45 high-power fields of view to ensure a sufficient sample volume is analyzed.
How much sample does the SediVue Dx analyzer need to run an analysis?
165 µL (0.165 mL)
How soon after collection does the sample need to be run?
Samples should be run within 30 minutes of collection. If this is not possible, urine should be stored in a clean, sealed container and refrigerated immediately (up to 12 hours). Samples should be brought to room temperature before analysis.
Do sample interferants have an effect on results (blood, lipids, icterus, debris, etc.)?
The SediVue Dx analyzer requires a minimum number of valid images (54) in order to provide accurate results. If images are too overcrowded (by RBCs, debris, etc.) or out of focus due to lipids, the SediVue Dx analyzer will flag the run, and dilution may be recommended. Learn more about automated sample messages. Watch how to prepare a dilution.
Can I dilute the sample?
Yes, dilutions are recommended in order to separate the formed elements from each other in a very crowded sample. Dilutions can be performed with normal saline (0.9%) up to 1:10 based on the severity of the crowding. Preanalytic dilutions may be performed when the sample visually appears hematuric or turbid. Postanalytic dilutions may also be performed and appended to the patient record for a before and after review. The SediVue Dx software will automatically recalculate the results based on the dilution factor. You will only be charged for the first patient run for the same patient ID in a 24-hour period. Watch how to prepare a dilution.
Can I run other sample types on the SediVue Dx analyzer (thoracic fluid, semen, etc.)?
The SediVue Dx analyzer is validated for canine and feline urine. However, it can be used to capture digital images of many different samples types or species, but numerical results will be suppressed and only images will appear. It is also important to understand that this technology many not be suitable for all species or sample types (for example, a whole blood sample will have too many red blood cells (RBCs) and white blood cells (WBCs) and, therefore, will overcrowd the image). As a general rule, fluids that have lower concentrations of microscopy elements work better. Image quality is also better if the microscopic elements have a higher density than the sample liquid so they properly settle to the floor of the cartridge.
Is there any special sample preparation required?
Not particularly, however, we strongly recommend using the premeasured SediVue Pipette with a SediVue Pipette Tip to eliminate overfilling and leaking. Or you could use a 3 cc syringe with a SediVue Syringe Tip. In either case, it is critical to mix the sample 8–10 times prior to aspirating from the bottom third of the sample to ensure a homogenous sample as crystals can settle to the bottom in just a few seconds.
Results and images
How many images does the SediVue Dx analyzer take?
70 high-resolution images. Each image is equivalent to two-thirds of a high-power field. There are 45 fields of view in total.
How many images should I review?
A minimum of 3 images should be reviewed with every sample run to confirm the quantitative results reported. It's best practice to review 12 images. All 70 images can be reviewed at any time on the IDEXX VetLab Station. Get guidance for reviewing images.
How many images are saved in the IDEXX VetLab Station?
The IDEXX VetLab Station will retain all 70 images for every sample run for 30 days. After 30 days, only the images marked as priority by the SediVue Dx analyzer or by the user (a minimum of 3 and up to 6) are retained.
How many images are saved in the VetConnect PLUS?
Only the images marked as priority by the SediVue Dx analyzer or by the user are sent to VetConnect PLUS (up to 6). These images are retained indefinitely.
How does the SediVue Dx Analyzer select and prioritize which images to show?
Each of the 70 SediVue Dx images is scanned by the convolutional neural network (a complex pattern-recognition software algorithm) to identify, classify, and count the formed elements. Each image is given a score based on the absence or presence of formed elements and the clinical significance for each element found. The images are then sorted, with the highest-scoring images displayed first and the lowest-scoring images displayed last.
Will images print out on the patient report?
The middle section of the first priority image will be printed on the patient report by default. To conserve printer ink, this is optional and can be turned 'Off' on the SediVue Setting screen.
Can the customer deselect the images the SediVue Dx analyzer chose as top priority (3 images) and choose their own images themselves?
No, there is no way to deselect the images that the SediVue Dx analyzer has chosen as top priority. However, the customer has the option to select 3 additional images to also save to the patient record for a total of 6 images (3 analyzer-selected images and 3 customer-selected images).
Why are the image tags not available?
There are several reasons why tags may not appear on your images:
- No tags for quality control when viewed on the IDEXX VetLab Station
- No tags for bacteria
- No tags for any elements when the results include the image review/dilute flag (crowded sample, results suppressed)
- No tags with unsupported species or unsupported sample type
Can images be printed with tags?
Yes, images can be printed with tags from the IDEXX VetLab Station. However, they cannot be included from VetConnect PLUS.

What is the average expiration of a SediVue V70i Cartridge/sleeve of cartridges?
Shelf life is 3 years.
How do I order more SediVue V70i Cartridges?
Two sleeves of cartridges will come for initial installation day. After that, based on your usage, two sleeves will be shipped automatically as needed. More SediVue Pipette Tips will also arrive when cartridges arrive. The SediVue Quality Control will also be shipped automatically. SediVue Syringe Tips and cleaning supplies need to be ordered online at idexx.com/order. Learn about worry-free inventory management.
How do I change the cartridge sleeve?
The bar code that is scanned when installing a new cartridge sleeve can be found on the inside of the cartridge sleeve box attached to the cartridge sleeve. Watch a snippit to learn how to change the cartridge sleeve.
How do I store my cartridge sleeves?
SediVue V70i Cartridges can be stored at room temperature for up to 3 years. If you accidentally put the cartridges in the freezer, please allow the cartridges to come back to room temperature to reduce any fog/condensation that might have occurred because of the temperature change.
Why is there a discrepancy between the number of cartridges left in the sleeve and the number listed on the IDEXX VetLab Station?
Causes of cartridge sleeve discrepancies can include the following:
- Last sleeve was not scanned in.
- Different bar code was used than the one on the package.
- Cartridges fell out of sleeve during installation or troubleshooting. Watch how to change the cartridge sleeve.
- Incorrect number of cartridges were installed in sleeve in factory (rare).
SediVue Bacteria Confirmation Kit
When should I use the SediVue Bacteria Confirmation Kit?
You should use the kit if:
- You receive a bacteria result of “Suspect presence” and the corresponding images do not provide conclusive evidence of the absence or presence of bacteria.
- You receive a bacteria result that does not align with the corresponding images and/or your expectations.
How does the SediVue Bacteria Confirmation Kit help to clarify my bacteria results?
The reagents in the kit dissolve crystalline and cellular material, allowing better visibility to the absence or presence of bacteria.
How do I interpret my results obtained after using the SediVue Bacteria Confirmation Kit?
Your results will report rods and cocci as either “None detected” or “Present.” As always, be sure to use the corresponding images along with results to make the most informed decision.
I received a message stating the SediVue Bacteria Confirmation Kit didn’t dissolve enough nonbacterial sediment. What do I do?
This message indicates that the images are not clear enough to confidently identify the absence or presence of bacteria. To resolve, review the images to determine if further action is needed and/or do one of the following:
- Rerun the bacteria confirmation kit using 165 µL from the original sample mixed with 2 drops of each reagent.
- Perform an air-dried cytological preparation (“dry prep”).
- Perform a urine culture.
Will I be charged for running the SediVue Bacteria Confirmation Kit?
You will not be invoiced for running the bacteria confirmation kit as long as it’s run as part of a complete urine sediment analysis.
How do I order another SediVue Bacteria Confirmation Kit?
A new kit will be shipped to you, via autoreplenishment, based on your usage and the kit expiration date. Should you need to order beforehand, call your IDEXX Inside Sales Representative.
