Problem description:

Female, 44 years old. In the blood test report I just made, the ESR equation K is 7.53 (reference range 13-93), the blood yield stress is 2.59 (reference range 6.84- 15.07), and the erythrocyte electrophoresis time is 13.69 (reference range17).

Analysis:

K value of erythrocyte sedimentation rate equation

The erythrocyte sedimentation rate is closely related to the change of blood composition, and the change of blood composition is directly related to the number of red blood cells (HCT). Erythrocyte sedimentation rate depends on HCT to a great extent, and HCT becomes the main factor affecting erythrocyte sedimentation rate. If HCT is high, ESR will slow down. On the contrary, ESR will increase and HCT will decrease. There is a certain mathematical relationship between ESR and HCT Through the calculation of K value of erythrocyte sedimentation rate equation, erythrocyte sedimentation rate is transformed into an index independent of HCT, so that K value of erythrocyte sedimentation rate equation can reflect the change of erythrocyte aggregation more objectively than erythrocyte sedimentation rate.

Normal reference value: 14-94

Clinical significance: the ESR equation k value exceeds the normal reference value, that is, the erythrocyte aggregation increases and the erythrocyte sedimentation rate accelerates at >: 94: 00. Relationship between erythrocyte sedimentation rate and equation k value;

1) The erythrocyte sedimentation rate rises rapidly, and the K value is large, indicating that the erythrocyte aggregation is high and the erythrocyte sedimentation rate is definitely fast.

2) The erythrocyte sedimentation rate is normal, but the K value is high, indicating that HCT is increased and erythrocyte aggregation is not high, indicating that the erythrocyte sedimentation rate is still fast.

3) The erythrocyte sedimentation rate is fast, but the K value is normal, indicating that HCT is reduced, but the erythrocyte aggregation is not high, and the actual erythrocyte sedimentation rate is not fast.

4) The erythrocyte sedimentation rate is normal, the K value is normal, and the erythrocyte sedimentation rate must be normal, indicating that the erythrocyte aggregation is not high.

ESR equation K value: In order to reflect erythrocyte aggregation more accurately, it is necessary to eliminate the influence of hematocrit, which makes ESR equation K value, that is, the ESR correction value after removing the influence of hematocrit, can correct the "false" growth rate of ESR caused by anemia or hemodilution, so only when ESR equation K value increases can erythrocyte aggregation be judged by the above six or seven indicators:

K value of erythrocyte sedimentation rate of erythrocyte aggregation

High and high.

High normal normal

Normal height

Normal, normal, normal.

The purpose of calculating the k value of ESR equation is to eliminate the influence of hematocrit interference and objectively reflect the aggregation of red blood cells. N2 of t | k value "

The formula is as follows: k = ESR/-[1-h+ina] s.

Wherein: ESR is ESR; H is hematocrit, which can be converted Into decimals (for example, when H is 40%, it can be converted into 0.40): 1-H is the ratio of plasma: in, which refers to the natural logarithm based on E (i.e. Ig2.7 1828).

A low ESR K indicates that your ESR may be anemia.

I suggest you go to the relevant departments of the hospital for further examination. Good luck!
