Why do blood samples need to be centrifuged?</h3>
The effect of heparinized blood sample centrifugation time on clinical chemistry and immunology results has rarely been studied. The WHO recommended a 15-minute centrifugation time without citing any scientific publications. The time spent centrifuging has a significant impact on the turnaround time.
On a Roche Cobas 6000 system, we examined 74 parameters in samples from 44 patients to see if there was a statistically significant difference in test results between specimens centrifuged at 2180 g for 15 minutes, 2180 g for 10 minutes, or 1870 g for 7 minutes. For each centrifugation condition, two tubes with different plasma separators (both Greiner Bio-One) were used. Deming fit was used to make statistical comparisons.

A structure found on the femur is the intercondylar fossa.
Explanation:
The intercondylar fossa is the notch or groove like structure like a depression present between the lateral and the medial femoral condyles.
The lower posterior end or surface of the femur bone constituted by the articular surfaces aids in articulation with the tibial surfaces and these surfaces are separated by the intercondylar notch.
It helps to align the thigh bone with the knee joint and maintains the knee joint stability.
Cartilaginous knee ligaments like the anterior cruciate ligament runs through this fossa.
Activation of pepsinogen starts when hydrocholoric acid (HCl), which is secreted by the parietal cells partially activates pepsinogen (pepsinogen* in figure). This partially active enzyme then cleaves the peptide from other pepsinogen molecules to form active pepsin.
