HemataStat II™

A hematocrit centrifuge delivering quantitative readings for up to six blood samples from a single 60 second spin.

Separation Technology Inc.EKF Diagnostics’ HemataSTAT II™ is  a micro hematocrit centrifuge that provides a quantitative hematocrit reading for up to six blood samples from one 60 second spin.

Hematocrit is the volume percentage (%) of red blood cells in blood. The measurement is taken as the amount of red blood cells in relation to the amount of plasma from a spun sample.

HemataSTAT is ideal for point-of care and laboratory use in clinics and hospitals. Its compact size and the optional battery pack makes it well suited for outreach programs and also for veterinary settings.

HemataSTAT is a hematocrit centrifuge used in 100% of the plasma collection centers in the USA as it allows a simple hematocrit measurement and further on analysis of the plasma fraction for proteins.

 The multi-lingual display provides easy to follow instructions to ensure accurate results every time.

HemataStat II combines easy maintenance with a high degree of user safety, for example, heparinized ClearCrit™ tubes are used to collect the blood sample and are available in plastic, glass or Mylar® coated glass, designed for maximum user safety.

Two different diameters of tube are available for low and regular sample volumes.

Additional safety features includes the high quality HemataSEAL tube sealant. HemataSEAL eliminates leakages and blow-outs and ensures accurate and reliable results time after time.

HemataChek™ is a whole blood micro hematocrit reference control ideal for use with HemataStat II and other micro hematocrit centrifuges.  It requires no refrigeration, has a 2-year shelf life from date of manufacture, and a 31-day open vial stability.  It is packaged in low, normal and high levels or combinations

Frequently asked questions

HemataSTAT II is accurate +/- 1% if the hematocrit is displayed in whole numbers, +/- 0.5% if the hematocrit is displayed with the decimal.  When compared to the NCCLS method, the correlation coefficient is 0.9978.

HemataSTAT has been tested to be accurate from 16% to 60%. This does not necessarily mean that it will not read or that it is not accurate outside of that range. We have simply not done the testing. Customers’ independent tests have found HemataSTAT to measure extremely low hematocrits accurately.

No. The design and technologies utilized in HemataSTAT centrifuges eliminate the need for a maximum packing time test.

Yes. Ensure that the sample is well mixed first.

HemataSTAT results are not affected by air bubbles in the sample.

Most facilities use 1.1mm I.D. tubes. 0.5mm I.D. are generally used for pediatrics because of the smaller sample required.

The CPT code for spun hematocrits is 85013.

1. Fill the capillary tube ½ to ¾ full.

2. Let the specimen flow down the tube until it is near the dry end. Then place your finger over the wet end of the tube to stop the flow. (Stop the specimen before it goes into the area where the sealant will go – that area must remain dry.)

3. With the sealant on a flat surface, insert the dry end of the tube into the sealant, pushing it to the bottom of the tray. Twist the tube when removing it from the sealant to prevent the sealing plug from being extracted. Repeat.

4. Gently tap the sealed end of the tube on a flat surface.

  • Use HemataSEAL® tube sealant only.
  • Store HemataSEAL® at room temperature. Excessive heat will render the compound not suitable for positive sealing.
  • Do not smooth out the used sealant in order to extend its use. This may result in leakage or blowouts.

The blood should make contact with the self-sealing plug for at least 30 seconds before spinning.

A fully charged nickel metal hydride battery pack should provide greater than 75 spin cycles assuming that the time to read the tube is less than one minute and that the centrifuge is turned off when not in use

It is practical and relevant to use a control at the level in the same range as your most common patient result.  Follow your local quality control regulations.
