Liver Disease Screening

A Slovak partner recently cooperated with the Slovak Hepatology Society on a liver disease screening campaign. Haiim was used to collect whole blood samples from over 1,000 people for complete liver and lipid panels. Testing was brought to patients using POCT technology, and the entire screening process occurred on-site.

Rural and Remote Healthcare

Our partner Labpoc is a Brazilian company collaborating with the government to provide healthcare testing services to remote areas. Using Haiim with POCT devices, over 50 patients in rural areas were screened daily and over 15,000 tests were successfully completed. The portability of Haiim and other devices allowed for the delivery of diagnostic screening to underserved populations.

Your Questions Answered


Under normal circumstances, blood samples collected using Haiim can be used to conduct:

  • Kidney, lipid, liver function, and endocrine panels
  • Prostate cancer, drug, COVID-19, and diabetes mellitus (glucose) tests
  • Nutrition panels

Further assays can be conducted if the blood volume is sufficient. In many cases, a second blood draw can be performed on the same puncture site.

Haiim is currently available for professional use only as a microsampling solution for remote healthcare, mobile clinics, and other decentralized settings. 

We plan to design Haiim for at-home use in the near future.

We cannot guarantee that Haiim will function properly with every microtube. For optimal performance, please use one of the following microtubes:

  • BD Microtainer® Blood Collection Tubes
  • ​Greiner MiniCollect® Tubes
  • ​KANGJIAN Micro Blood Collection Tube
  • ​SARSTEDT Multivette® 600
  • Xinle Capillary Tube-A

Haiim has many advantages over fingertip squeezing methods, including a higher volume of blood, lower hemolysis, less pain, and better recovery.
