That means that if you had such a count, it wouldn’t necessarily reflect an underlying condition. But a 2016 study found that NRBC counts of 1.5/100 WBC (1.5%) or lower were usually not clinically significant. Anything higher might cause a doctor to perform further tests. It’s either written as a value per 100 WBCs or as a percentage.Īn ideal result would be 0.3/100 WBC (0.3%) or less. You may also see your NRBC count expressed as a value compared with your number of white blood cells (WBCs). A similar 2017 study found that the risk of death increased as NRBC count increased.

But some studies have an even lower threshold, ranging from 0.003 x 10 9/L (or 3/μL) to 0.01 x 10 9/L (10/μL).Ī 2021 study of emergency department cases found that any count higher than zero ( 0/μL) could increase your risk of death. It’s usually listed as billions of NRBCs per liter (x 10 9/L) or NRBCs per microliter (/μL).Ī doctor may consider your NRBC level to be elevated if it is higher than 0.02 x 10 9/L (20/μL). This value reflects how many NRBCs are in a certain amount of blood. You may see either of the following: Absolute value Labs can use different systems to measure the number of NRBCs in your blood. A positive result means that NRBCs have been found in the blood. Since NRBCs should not be present in adults’ blood, your doctor may want to investigate any positive result.
