Baraka -
You should get the DVDs from the 2009 Austin conference, and look at the images that Dr. Wymore captured, including black specks.
My understanding from the explanations offered is that what you are observing is "cracks" that occur when the blood dries, much as what happens when mud dries.
Bearing this in mind, the reason these lines do not form in the live blood analysis is because the drop of blood is trapped between two pieces of sterile glass and does not dry. The blood is "alive" for awhile because it is not exposed to air.
Dry Layer Oxidative Stress Test 
The image on the left is a dried layer of blood of a healthy individual. Notice how it is inter-connected with black connecting lines. The black interconnecting lines is a fibrin network. This is fibrinogen, one of the protein constituents of the blood. The red in-between the black lines are the red blood cells. The image to the right is of an individual who has cancer. Notice how the blood fails to coagulate completely and has many white areas. These are the polymerized protein puddles and they reflect oxidative stress. They represent the degradation of the body's extra cellular matrix from free radical activity. Since free radical activity has been implicated in nearly all disease processes, this test can be used as a quick reference to gauge the severity and extent of one's health problems. And here: The HLB Blood Test Robert W.Bradford.Dsc. & Herry W.Allen The detection of disseminated intravascular coagulation (DIC) by means of the HLB Blood Test is a natural consequence of the nature of the test itself. A small amount of blood expressed from a fingertip is contacted with a clean microscope slide in a series of drops which are allowed to dry in a normal manner. During this process, blood is allowed to clot/dry under microscopic observation. The pattern seen in healthy persons is essentially the same, a dense mat of red areas interconnected by black, irregular lines(fibrin net), completely filling the area of the drop. The HLB Blood Test - Darkfield microscope In other words, these lines ARE normal. I am NOT saying that there aren't things in the blood of Morgies that may be different, but (I am guessing here), very high power resolution would be necessary to see them, like 1000 X or more. Lastly, I didn't say my blood was "normal and healthy". There were many findings, but all were readily recognized by the technician and marked on a sheet of paper that each person gets who has this done. Recommendations for correcting these abnormalities are made. I will bring all these to the next meeting for you to look at, if you want. We need a trained microbiologist with the right equipment to work on this. I don't trust the CDC to "find" anything. SS
