No, the virus test would not, because the virus test tests for the virus. But the antibody test would at least show if you had the thing to begin with! (That does not mean that you are totally immune to a mutation of it, JUST LIKE THE DAMNED FLU, but it gives you peace of mind.)
Testing Front Line NHS next week, they'd of all had it, then they can stop going on about PPE and messing around like it's the damn plague.
It'll show if you've already had it with or without symptoms and therefore immune and you can't stop worrying about getting it. 99% sure I've had it, Loads of friends with it currently 30% area, be 80% then slow right down soon.
Based on 33% per day of growth ( wish my account did that ) after 84days, 100% would have, although it'll slow down at some stage 80% area I'd guess as lack of hosts to find. 0 10.00 1 13.30 2 17.69 3 23.53 4 31.29 5 41.62 6 55.35 7 73.61 8 97.91 9 130.22 10 173.19 11 230.34 12 306.35 13 407.45 14 541.90 15 720.73 16 958.58 17 1,274.91 18 1,695.62 19 2,255.18 20 2,999.39 21 3,989.19 22 5,305.62 23 7,056.47 24 9,385.11 25 12,482.20 26 16,601.32 27 22,079.76 28 29,366.08 29 39,056.88 30 51,945.66 31 69,087.72 32 91,886.67 33 122,209.27 34 162,538.33 35 216,175.98 36 287,514.05 37 382,393.69 38 508,583.61 39 676,416.20 40 899,633.54 41 1,196,512.61 42 1,591,361.77 43 2,116,511.15 44 2,814,959.84 45 3,743,896.58 46 4,979,382.45 47 6,622,578.66 48 8,808,029.62 49 11,714,679.39 50 15,580,523.59 51 20,722,096.38 52 27,560,388.19 53 36,655,316.29 54 48,751,570.66 55 64,839,588.98 56 86,236,653.35 57 114,694,748.95 58 152,544,016.10 59 202,883,541.42 60 269,835,110.08 61 358,880,696.41 62 477,311,326.23 63 634,824,063.88 64 844,316,004.96 65 1,122,940,286.60 66 1,493,510,581.18 67 1,986,369,072.97 68 2,641,870,867.05 69 3,513,688,253.17 70 4,673,205,376.72 71 6,215,363,151.04 72 8,266,432,990.88 73 10,994,355,877.87 74 14,622,493,317.57 75 19,447,916,112.37 76 25,865,728,429.45 77 34,401,418,811.17 78 45,753,887,018.86 79 60,852,669,735.08 80 80,934,050,747.66 81 107,642,287,494.39 82 143,164,242,367.54 83 190,408,442,348.82 84 253,243,228,323.93 might need 85, but you get the point.

The model reminds me of a financial bubble, like the bitcoin price chart, an exponential rise, then a collapse and then a second wave? Never mind, just my imagination.
